Time to Retire the 20% Bull/Bear Market Rule

September 1, 2015 Leave a comment

Officially, Crude Oil has had the worst bull market ever.

According to a headline on Bloomberg on Monday, Crude is in a bull market. The headline screamed “WTI CRUDE CLOSES UP 29% FROM AUG 24 LOW, ENTERS BULL MARKET”! On Tuesday, after a 7.7% fall from Monday’s close (-100%, annualized), the bull market doesn’t seem so…well, ebullient.

Okay, sure, this is a pet peave of mine. I don’t know whose idea it was to call a 20% advance from the prior low a bull market, and a 20% decline from the prior high a bear market, but I am pretty sure that they didn’t intend for that 20% to be applied to all markets, at all times. So a 5-year Treasury Note is not in a bear market until it falls 20 points (or…is that 20% of the current yield? I guess it depends who writes the headlines!), but energy futures which can move 20% in a couple of days, or corn futures which can double literally overnight if there is a drought, can be in bull and bear markets a couple of times per month. Does this make sense?

Add to this the obvious absurdity of the idea that we can know in advance whether an asset is in a bull or bear market. If you are telling me that Crude rallying 20% off the lows means that it is in a bull market, and that means I can be long Crude comfortably, knowing it is likely to rally from here – then you need to quit telling me anything and go make a fortune trading.

We can only know a bull market or a bear market in hindsight. That is, even if 20% is the magic number (and I can’t think of why that would be so), the best we can say is that Crude was in a bull market on Thursday, Friday, and Monday when it rallied about 27%. Does that help us, going into Tuesday?

Evidently not!

Commodities Beat-Down Continues

July 27, 2015 7 comments

The recent commodities sell-off has been breathtaking. This is especially true since the most-recent downturn occurred from a level where the expected future returns from commodity index investment were reasonably good – and, as a spread above expected equity or bond returns, probably around the best levels ever.

But investors have a strong tendency to use the current level, rather than some esoteric measure of value, as the level from which expected market moves are evaluated. What I mean by that is this: in theory, if some event happens in the capital markets, the reaction in the market should depend on whether that event has already been “discounted” in the current price. That is, if we are all expecting Microsoft to raise its dividend, then the price of Microsoft should reflect that change already, and when it subsequently actually happens it should have no effect on price. Indeed, if the market has overestimated the change in fundamental value, then the price of Microsoft should retrace somewhat when the news is actually announced. From that, we get the old saw that one should “buy the rumor, sell the news.”

The fact that this isn’t really what happens is not exactly news. In the early 1980s, Bob Shiller demonstrated that the volatility in the equity marketplace was much greater than the changes in the real underlying values should support.

In practice, investors don’t behave rationally. The same event can be discounted over, and over, and over again. Each investor, it seems, hears news and assumes the current price does not incorporate that news, no matter what has happened previously to the price. Based on my own unscientific observation, I think this is more true now that there are more retail investors, and news outlets that benefit from making everything sound like new information. If my supposition is true, one implication is that markets can deviate further and further from fundamental values. In other words, we get more bubbles and inverse bubbles than we would otherwise.

As a great current example, we might consider commodities. The slowdown in China’s economic activity is discounted anew almost every day, as more information comes out from that country that its economic engine is (at least) sputtering. One would think that China was the only consumer of industrial metals and energy, and that its consumption is going to zero, based on the behavior of these markets. And with every tick higher in the dollar, every commodity seems offered. It’s risk-off, then risk-off again, then risk-off again, ad infinitum.


Now, there is no doubt that commodities in 2008 were overvalued, and arguably in 2011 they were also expensive. But the four-year beat-down of commodities – pretty much the only asset class that has declined in value over that time period – is breathtaking in its depth and, as it turns out, its breadth. I was curious about whether the recent break of major commodities indices to new lows – below the lows of 2008, when it felt like the world was ending (see chart above, source Bloomberg) – was broader, in that it seemed like every commodity was participating. So I put together a chart that shows the proportion of commodities (considering only the 27 major traded commodities that are in the Bloomberg Commodity Index) that were above their 200-day moving averages. The chart is below (Source: Enduring Investments).

commodiffusIt isn’t quite as bad as I had thought. The recent slide has taken the proportion back to 18% (meaning 82% are below their 200-day moving averages), but commodity prices have been sliding for so long that the 200-day averages are now generally declining pretty smartly. Notice in general the post-2011 average, compared to the pre-2008 average. Even without seeing the price chart, you can tell the 2011-2015 bear market from the 2002-2008 bull market!

One other observation about commodities, to be fair. The chart I showed, above, of the Bloomberg Commodity Index, incorporates carry in commodities. That is, it adds the futures roll, and collateral return, to the movement in spot commodities. Over the last few years, the collateral return hasn’t been very good and the roll return has actually been substantially negative, so that the return of spot commodities has in fact been better than the return to commodity indices. The chart below (source: Bloomberg) shows the Bloomberg Spot Commodity Index; you can see that we are still above the 2008 lows.

commodspotBeing “above the 2008 lows” doesn’t strike me as a strong performance. Stocks are also above the 2008-09 lows, by 200% or so. LQD, the investment-grade bond ETF, is about 45% higher. HYG, the high-yield ETF, is 41% higher. Heck, M2 money supply is around 50% higher than it was in early 2009.

And yet, every time we hear more news about China, investors behave as if it is new information, and sell commodities off some more. As I said above, these moves can last longer these days than they did in the past – but this is unsustainable. With commodities, an added complexity is that investors don’t know how to evaluate expected return (since there are no cash flows), and so it is hard for them to compare “value” to other asset classes. But the value is there.

Money, Commodities, Balls, and How Much Deflation is Enough?

January 22, 2015 2 comments

Money: How Much Deflation is Enough?

Once again, we see that the cure for all of the world’s ills is quantitative easing. Since there is apparently no downside to QE, it is a shame that we didn’t figure this out earlier. The S&P could have been at 200,000, rather than just 2,000, if only governments and central banks had figured out a century ago that running large deficits, combined with having a central bank purchase large amounts of that debt in the open market, was the key to rallying assets without limit.

That paragraph is obviously tongue-in-cheek, but on a narrow time-scale it really looks like it is true. The Fed pursued quantitative easing with no yet-obvious downside, and stocks blasted off to heights rarely seen before; the Bank of Japan’s QE has added 94% to the Nikkei in the slightly more than two years since Abe was elected; and today’s announcement by the ECB of a full-scale QE program boosted share values by 1-2% from Europe to the United States.

The ECB’s program, to be sure, was above expectations. Rather than the €50bln per month that had been mooted over the last couple of days with little currency-market reaction, the ECB pledged €60bln. And they promised to continue until September 2016, making the total value of QE around €1.1 trillion. (That’s about $1.3 trillion at today’s exchange rate, but of course if it works then it will be much less than $1.3 trillion at the September 2016 exchange rate). To be sure, a central bank always has the prerogative to change its mind, but on the risks of a sudden change in policy please see “Swiss National Bank”. It really is remarkable that Draghi was able to drag the Bundesbank kicking and screaming into this policy choice, and it is certain to end the threat of primary deflation in Europe just as it did in the U.S. and in Japan. It will likely also have similar effects on growth, which is to say “next to nothing.” But in Europe, deflation risks stemming from slow money growth had been a risk (see chart, source Bloomberg).


Interestingly, y/y money growth had already been accelerating as of late last year – the ECB releases M2 with a very long lag – but this puts the dot on the exclamation point. The ECB has said “enough!” There will be no core deflation in Europe.

Commodities: How Much Deflation is Enough?

Last week, in “Commodities Re-Thunk” and “Little Update on Commodities Re-Thunk”, I presented the results of using a generalization of the Erb & Harvey approach to forecast expected long-term real returns for commodities. It occurred to me that, since I have previously played with long-term real equity returns, and we have the real yield on 10-year TIPS as well, that it would be interesting to see if using these figures might produce a useful strategy for switching between assets (which doesn’t change the fact that I am a long-term investor; this is still based on long-term values. We merely want to put our assets in whatever offers the best long term value at the moment so as to maximize our expected long-term return).

The answer is yes. Now, I did a more-elegant version of what I am about to show, but the chart below shows the results of switching 100% of your assets between stocks, commodities, and TIPS based on which asset class had the highest expected real yield at a given month-end. Each line is an asset class, except for the blue line which shows the strategy result.


The labels at the top show the asset class that dominated for a long period of time. In 2005 there were a couple of quick crossovers that had little impact, but by and large there were three main periods: from 1999-2005, commodities offered excellent expected real returns; from mid-2005 through early-2008 the strategy would have been primarily in TIPS, and subsequent to that the strategy would have been primarily in equities. Fascinating to me is that the overall strategy does so well even though it would have been invested in equities throughout the crash in 2008. The crash in commodities was worse.

Now what is really interesting is that there is a vertical line at the far right-hand side of the chart. That is because at the end of December, the expected real return to commodities finally exceeded that of equities for the first time in a very long time. For this “selling out” strategy, that means you should be entirely out of stocks and TIPS and entirely in commodities.

As I said, that is the coarse version of this approach. My more-elegant version optimized the portfolio to have a constant expected risk in real terms. It was much less risky as a result (10.5% annualized monthly standard deviation compared to 15.5% for the strategy shown above), had lower turnover, but still sported returns over this period of 9.5% compounded compared to 11.2% for the strategy above. I am not, in other words, suggesting that investors put 100% of their assets in commodities. But this method (along with lots of other signals) is now suggesting that it is time to put more into commodities.

Balls: How Much Deflation is Enough?

Being a football fan, I can’t keep from weighing in on one mystery about deflate-gate (incidentally, why do we need to put ‘gate’ on the end of every scandal? It wasn’t Water-gate, it was the Watergate Hotel that proved Nixon’s undoing. “Gate” is not a modifier). Really, this part isn’t such a mystery but I have seen much commentary on this point: “How did the balls get deflated during the game since they were approved before the game?”

The answer is really simple in the real world: the official picked up one of the balls, said “fine”, and put them back in the bag. He has a million things to do before the championship game and in years of refereeing he has probably never found even one ball out of spec. This sort of error happens everywhere there are low reject rates, and it’s why good quality control is very difficult. (Now, if you fired the ref every time a bad ball got through, you damn betcha those balls would be measured with NASA-like precision – which is perhaps a bad metaphor, since similar issues contributed to the Challenger disaster). The real mystery to me is: if the Patriots truly think they are the better team, why would they cheat, even a little? As with the CHF/EUR cross that we discussed yesterday, the downside is far worse than the gain on the upside.

Or, is it? The NFL will have a chance to establish the cost of recidivism in cheating. Maybe the Patriots were simply betting that the downside “tail” to their risky behavior was fairly short. If the NFL wants to put a stop to nickel-and-dime cheats, it can do that by dropping the hammer here.

Little Update on Commodity Re-Thunk

January 13, 2015 4 comments

Reading some of the comments people have posted in various places, I thought it would make sense to spend the time to re-create the projected-index chart in the prior article, but using something approximating GSCI weights. The GSCI is production-weighted, which means it is very heavily energy-linked (I used 2008 weights just because they were the first ones I found: 78% energy, 10% agriculture, 6% industrial metals, 3% meats, 3% precious metals), yet I was comparing its 10-year real return to an equal-weighted “prediction.” How much does this change the picture?

As it happens, quite a bit. Here is the new chart (sourced: Enduring Investments).


Commodities Re-Thunk

January 13, 2015 12 comments

I want to talk about commodities today.

To be sure, I have talked a lot about commodities over the last year. Below I reprise one of the charts I have run in the past (source: Bloomberg), which shows that commodities are incredibly cheap compared to the GDP-adjusted quantity of money. It was a great deal, near all-time lows this last summer…until it started creating new lows.


Such an analysis makes sense. The relative prices of two items are at least somewhat related to their relative scarcities. We will trade a lot of sand for one diamond, because there’s a lot of sand and very few diamonds. But if diamonds suddenly rained down from the sky for some reason, the price of diamonds relative to sand would plummet. We would see this as a decline in the dollar price of diamonds relative to the dollar price of sand, which would presumably be stable, but the dollar in such a case plays only the role of a “unit of account” to compare these two assets. The price of diamonds falls, in dollars, because there are lots more diamonds and no change in the amount of dollars. But if the positions were reversed, and there were lots more dollars, then the price of dollars should fall relative to the price of diamonds. We call that inflation. And that’s the reasoning behind this chart: over a long period of time, nominal commodities prices should grow with as the number of dollars increases.

Obviously, this has sent a poor signal for a while, and I have been looking for some other reasonable way to compute the expected return on commodities.[1] Some time ago, I ran across an article by Erb and Harvey called The Golden Dilemma (I first mentioned it in this article). In it was a terrific chart (their Exhibit 5) which showed that the current real price of gold – simply, gold divided by the CPI price index – is a terrific predictor of the subsequent 10-year real return to gold. That chart is approximately reproduced, albeit updated, below. The data in my case spans 1975-present.


The vertical line indicates the current price of gold (I’ve normalized the whole series so that the x-axis is in 2015 dollars). And the chart indicates that over the next ten years, you can expect something like a -6% annualized real return to a long-only position in gold. Now, that might happen as a result of heavy inflation that gold doesn’t keep up with, so that the nominal return to gold might still beat other asset classes. But it would seem to indicate that it isn’t a great time to buy gold for the long-term.

This chart was so magnificent and made so much sense – essentially, this is a way to think about the “P/E ratio” for a commodity” that I wondered if it generalized to other commodities. The answer is that it does quite well, although in the case of many commodities we don’t have enough history to fill out a clean curve. No commodities work as well as does gold; I attribute this to the role that gold has historically played in investors’ minds as an inflation hedge. But for example, look at Wheat (I am using data 1970-present).


There is lots of data on agricultural commodities, because we’ve been trading them lots longer. By contrast, Comex Copper only goes back to 1988 or so:


Copper arguably is still somewhat expensive, although over the next ten years we will probably see the lower-right portion of this chart fill in (since we have traded higher prices, but only within the last ten years so we can’t plot the subsequent return).

Now the one I know you’re waiting for: Crude oil. It’s much sloppier (this is 1983-present, by the way), but encouraging in that it suggests from these prices crude oil ought to at least keep up with inflation over the next decade. But do you know anyone who is playing oil for the next decade?


For the sake of space, here is a table of 27 tradable commodities and the best-fit projection for their next 10 years of real returns. Note that most of these fit a logarithmic curve pretty reasonably; Gold is rather the exception in that the historical record is more convex (better expectation from these levels than a pure fit would indicate; see above).


I thought it was worth looking at in aggregate, so the chart below shows the average projected returns (calculated using only the data available at each point) versus the actual subsequent real returns of the S&P GSCI Excess Return index which measures only the return of the front futures contract.


The fit is probably better in reality, because the actual returns are the actual returns of the commodities which were in the index at the time, which kept changing. At the beginning of our series, for example, I am projecting returns for 20 commodities but the 10-year return compares an index that has 20 commodities in 1998 to one that has 26 in 2008. Also, I simply equal-weighted the index while the S&P GSCI is production-weighted. And so on. But the salient point is that investing in spot commodities has been basically not pretty for a while, with negative expected real returns for the spot commodities (again, note that investing in commodity indices adds a collateral return plus an estimate 3-4% rebalancing return over time to these spot returns).

Commodities are, no surprise, cheaper than they have been in a long while. But what is somewhat surprising is that, compared to the first chart in this article, commodities don’t look nearly as cheap. What does that mean?

The first chart in this article compares commodities to the quantity of money; the subsequent charts compare commodities to the price level. In short, the quantity of money is much higher than has historically been consistent with this price level. This makes commodities divided by M2 look much better than commodities divided by the price level. But it merely circles back to what we already knew – that monetary velocity is very low. If money velocity were to return to historical norms, then both of these sets of charts would show a similar story with respect to valuation. The price level would be higher, making the real price of commodities even lower unless they adjusted upwards as well. (This is, in fact, what I expect will eventually happen).

So which method would I tend to favor, to consider relative value in commodities? Probably the one I have detailed here. There is one less step involved. If it turns out that velocity reverts higher, then it is likely that commodities real returns will be better than projected by this method; but this approach ignores that question.

Even so, a projected real return now of -2% to spot commodities, plus a collateral return equal to about 1.9% (the 10-year note rate) and a rebalancing return of 3-4% produces an expected real return of 2.9%-3.9% over the next decade. This is low, and lower than I have been using as my assumption for a while, but it is far higher than the expected real returns available in equities of around 1.2% annualized, and it has upside risk if money velocity does in fact mean-revert.

I will add one final point. This column is never meant to be a “timing” column. I am a value guy, which means I am always seen to be wrong at the time (and often reviled, which goes with the territory of being a contrarian). This says absolutely nothing about what the returns to commodities will be over the next month and very little about returns over the next year. But this analysis is useful for comparing other asset classes on similar long-term horizons, and for using useful projections of expected real returns in asset allocation exercises.

[1] In what follows, I will focus on the expected return to individual spot commodities. But remember that an important part of the expected return to commodity indices is in rebalancing and collateral return. Physical commodities should have a zero (or less) real return over time, but commodity indices still have a significantly positive return.

Winter is Coming … But Not Here, Not Yet

January 12, 2015 5 comments

We began 2014 with the perspective that the economy was limping along, barely surviving. A recession looked possible simply because the expansion was long in the tooth, but there weren’t any signs of it yet. Equity markets were priced for robust growth, which was clearly not likely to happen, but commodities and fixed-income markets were priced for disaster which was also not likely to happen. The investing risks were clearly tilted against stocks and bonds, given starting valuations, but although the economic landscape appeared weak it was not horrible.

Beginning 2015, the economic news is much better – at least, domestically. Unemployment is back to near levels associated with mid-cycle expansions, although there are still far too many people not in the workforce and a still-disturbing number of people who say they “want a job now” and would take one if offered (see chart, source Bloomberg).


More encouraging still, commercial bank credit growth is back to near 8% y/y, which is consistent with the booms of the past 30 years (see chart, source FRB). And this number excludes peer-to-peer lending and other sorts of credit growth that occur outside of the commercial bank framework, which is likely additive on a multi-year time frame.


The dollar is up and commodities are down, both of which are good for the US economy generally although bad for some groups of course (notably the oil patch). But the US is a net consumer of commodities, so commodity bear markets are good for US growth.

Outside of the US, though, things are looking decidedly worse. Although European core inflation recently surprised on the high side, it is still only at 0.8% and with GrExit a real possibility it is very hard to get bullish economically on the continent. China’s growth is softening. Emerging markets are not behaving well, especially the dollarized economies.

This recent development of the US as an island of relative tranquility in a sea of disquiet is interesting to me. Why are interest rates in the US so low, given that our economy is growing? 30-year interest rates at 2.5% and 10-year rates at 1.90%, with core inflation at 1.7% (and median inflation, as I like to point out because it isn’t influenced by outliers, at 2.3%) seems dissonant as the economy grows at 2.5%-3% and inflation in the US seems reasonably floored in the long run at 1.5%-2.0% as long as the Fed is credible.

This isn’t a new phenomenon, but I think the causes are new. Over the last five years, nominal interest rates were lower than they ought otherwise have been because the Fed was buying trillions of Treasuries and squeezing investors who needed to own fixed income. But the Fed is no longer buying and the Treasury is still issuing them. So I believe the causes of low interest rates now are different than the causes were over the last half-decade. Specifically, the causes of low interest rates in the last five years were sluggish global growth and extensive central bank QE; the causes currently are flight-to-quality related.

It seems weird to talk about a “flight to quality” in US bonds without stocks also plunging. But we have an analog for this period. Here is where I depart totally into intuition, which is in this case driven by experience. This period of interest rates declining while growth rises, as the economy continues a rebound after a long recession, with commodities declining and stocks rising, feels to me like late 1997. It feels like “Asian Contagion.”

Back in 1997, there was a lot of concern about how the Asian financial crisis would spill into US markets. Rates dropped (100bps in the 10y between July 1, 1997 and January 12, 1998), commodities dropped (the index now known as the Bloomberg Commodity Index fell 25% between October 1997 and June 1998), the S&P rallied (+23% from November 1997-April 1998), and GDP growth printed 5.2%, 3.1%, 4.0%, and 3.9% from 1997Q3 to 1998Q3. Meanwhile, Asian markets and economies were all but collapsing.

There was much fear at the time about the impact that the Asian Contagion would have on the US, but this country never caught a cold partly because (a) interest rates were depressed by the flight-to-quality and (b) declining commodities, especially energy, are bullish for US growth overall. We did not, of course, escape unscathed – later in 1998, a certain large hedge fund (which was small compared to some hedge funds today) threatened to cause large losses at some money center banks, and the Fed stepped in to save the day. That was a painful period in the equity market, but the effect from the Asian crisis was indirect rather than direct.

The parallels aren’t perfect; for one thing, bond yields are much lower and equity multiples much higher than their equivalents of the time, and commodities had already fallen very far before the recent slide. I would be reluctant to expect another hundred basis point rally in bonds and another large rally in stocks from these levels, although 1997-1999 saw these things. But history doesn’t repeat – it rhymes. I seem to hear this rhyme today.

Why does it matter? I think it matters because if I am right it means we are witnessing the end of long-term crisis-related markets, but they are masked by the arrival of short-term crisis-related markets. This means the unwind that we would have expected from the Fed’s ending of the purchase program – a slow return to normalcy – might instead end up looking like the unwind that we can get from short-term flight-to-quality crisis flows, which can be much more rapid. Again, this is all speculation and intuition, and I present no proof that I am right. I am merely proposing this speculation for my readers’ consumption and consideration.

Seasonal Allergies

Come get your commodities and inflation swaps here! Big discount on inflation protection! Come get them while you can! These deals won’t last long!

Like the guy hawking hangover cures at a frat party, sometimes I feel like I am in the right place, but just a bit early. That entrepreneur knows that hangover cures are often needed after a party, and the people at the party also know that they’ll need hangover cures on the morrow, but sales of hangover cures are just not popular at frat parties.

The ‘disinflation party’ is in full swing, and it is being expressed in all the normal ways: beat-down of energy commodities, which today collectively lost 3.2% as front WTI Crude futures dropped to a 2-year low (see chart, source Bloomberg),


…10-year breakevens dropped to a 3-year low (see chart, source Bloomberg),


…and 1-year inflation swaps made their more-or-less annual foray into sub-1% territory.


So it helps to remember that none of the recent thrashing is particularly new or different.

What is remarkable is that this sort of thing happens just about every year, with fair regularity. Take a look at the chart of 10-year breakevens again. See the spike down in late 2010, late 2011, and roughly mid-2013. It might help to compare it to the chart of front Crude, which has a similar pattern. What happens is that oil prices follow a regular seasonal pattern, and as a result inflation expectations follow the same pattern. What is incredible is that this pattern happens with 10-year breakevens, even though the effect of spot oil prices on 10-year inflation expectations ought to be approximately nil.

What I can tell you is that in 12 of the last 15 years, 10-year TIPS yields have fallen in the 30 days after October 15th, and in 11 of the past 15 years, 10-year breakevens were higher in the subsequent 30 days.

Now, a lot of that is simply a carry dynamic. If you own TIPS right now, inflation accretion is poor because of the low prints that are normal for this time of year. Over time, as new buyers have to endure less of that poor carry, TIPS prices rise naturally. But what happens in heading into the poor-carry period is that lots of investors dump TIPS because of the impending poor inflation accretion. And the poor accretion is due largely to the seasonal movement in energy prices. The following chart (source: Enduring Investments) shows the BLS assumed seasonality in correcting the CPI tendencies, and the actual realized seasonal pattern over the last decade. The tendency is pronounced, and it leads directly to the seasonality in real yields and breakevens.


This year, as you can tell from some of the charts, the disinflation party is rocking harder than it has for a few years. Part of this is the weakening of inflation dynamics in Europe, part is the fear that some investors have that the end of QE will instantly collapse money supply growth and lead to deflation, and part of it this year is the weird (and frustrating) tendency for breakevens to have a high correlation with stocks when equities decline but a low correlation when they rally.

But in any event, it is a good time to stock up on the “cure” you know you will need later. According to our proprietary measure, 10-year real yields are about 47bps too high relative to nominal yields (and we feel that you express this trade through breakevens rather than outright TIPS ownership, although actual trade construction can be more nuanced). They haven’t been significantly more mispriced than that since the crisis, and besides the 2008 example they haven’t been cheaper since the early days (pre-2003) when TIPS were not yet widely owned in institutional portfolios. Absent a catastrophe, they will not get much cheaper. (Importantly, our valuation metric has generally “beaten the forwards” in that the snap-back when it happens is much faster than the carry dynamic fades).

So don’t get all excited about “declining inflation expectations.” There is not much going on here that is at all unusual for this time of year.
