uncharted territory?

One of the fallacies about the recent financial turbulence is that the markets are in “uncharted territory” and that there are no historical precedents for the volatility, panic, or economic uncertainty that we've observed. To make statements like this is to admit that one has not examined historical evidence prior to the 1990's. The fact is that we've observed similar panics throughout market history. This decline has been deeper and more rapid than most, but that is largely a reflection of the rich valuation and overbought condition that characterized the market in 2007.

If we seriously deem it necessary to talk about the Great Depression, fine. Even the Great Depression can be adequately used as a precedent for current conditions provided that one recognizes that the market's valuation during the Depression didn't fall to the levels we currently observe until 1931 when the rate of unemployment was already 15%. Sure, if U.S. unemployment is headed to 25%, as it did in the Great Depression, then stock prices might fall in half even from here, as they did by 1932. But this is important – even if stock prices were to fall further, it would not be because of earnings losses that would permanently impair the fundamental value of U.S. companies. Rather, if further losses emerge, it will be because of increases in risk premiums that will be associated with extremely high subsequent returns. Indeed, even though unemployment shot to 25% in 1932, the S&P 500 more than doubled in the year following the 1932 Depression low, and tripled off of that low within less than three years.

The handful of historical instances when stocks fell to 7 times prior record earnings were also points that were accompanied by 15-25% unemployment, 12% yields on commercial paper (as at the 1974 lows), or 15% Treasury yields (as at the 1982 lows). Similar data is unlikely in this instance – and even if conditions deteriorate to that point, it will involve months and months of ebb and flow in the economic reports. We can be virtually certain that stocks would experience enormous rallies, not simply continuous decline, while the evidence accumulates. Meanwhile, it is notable that data that measure investor panic, such as risk-premiums and intra-day market volatility, already match historical extremes (1932, 1974, 1982, and 2002) – points where stock prices were not far from their lows even though negative economic news persisted for a longer period.

That's not to say that I believe stocks have “hit their lows.” We always have to allow for the market to move significantly and unexpectedly, and there is plausible downside risk from here. Our activity as investors is not to try to identify tops and bottoms – it is to constantly align our exposure to risk in proportion to the return that we can expect from that risk, given prevailing evidence.

Investors can get a good understanding of market history by examining a great deal of data, or by living through a lot of market cycles and learning something along the way. Only investors who have done neither believe that current conditions are “uncharted territory.” Veterans like Warren Buffett and Jeremy Grantham have a good handle on both historical data, and on the concept that stocks are a claim to a very long-term stream of future cash flows. They recognize that even wiping out a year or two of earnings does no major damage to the intrinsic value of companies with good balance sheets and strong competitive positions. Most importantly, these guys never changed their standards of value even when other investors were bubbling and gurgling about a new era of productivity where knowledge-based companies would make the business cycle obsolete, and where profit margins would never mean-revert. They knew to ignore the reckless optimism then, because they understood that stocks were claims on a very long-term stream of cash flows. They know to ignore the paralyzing fear now, because they still understand that stocks are a claim on a very long-term stream of cash flows.

If we seriously need to talk about the Great Depression (I personally believe that it is an outrageously dire comparison), we should recognize that even during that prolonged decline, it rarely made sense to sell into a major break of a previous low, because investors invariably had a chance to sell on a later recovery to the prior level of support. Below is a chart of the Dow Jones Industrial Average during the Depression. Even if one hung on after the enormous rally of nearly 50% that followed the initial 1929 low, the market's initial break of that low (the first horizontal bar) was followed several months later by a rebound to that prior level of support. The break of the second intermediate low of early 1931 (the second horizontal bar) was followed by a rebound later in the year to that same level. Third break, same story.

It is a typical market dynamic to have massive rallies toward prior levels of support, even within ongoing market declines. Once valuations are favorable, that tendency is even stronger, even in a weakening economy. Only the final panic decline of a bear market offers investors virtually no chance to get out on rebounds, but it is precisely that final decline that is recovered almost immediately in the subsequent bull market.

Even if the U.S. economy experiences a much deeper recession, I believe that the 1000-1100 level on the S&P represents a reasonable estimate of “fair value” for the S&P 500. That estimate is somewhat conservative since I am adjusting for the fact that earnings in recent years have been based on very wide profit margins, but could be too conservative given that long-term interest rates are very low. Long-duration instruments like stocks should not be priced off of short-duration instruments like 10-year Treasury bonds, or even 30-year Treasuries, so low interest rates shouldn't make investors recklessly optimistic about their valuation estimates. In any event, I do believe that current levels represent value from the standpoint of long-term investment prospects.

As for extreme and less likely benchmarks, the 780 level on the S&P 500 would represent a 50% loss from the market's peak, and would put the market in the lowest 20% of all historical valuations. I would expect heavy demand from value-conscious investors about that level if the market were to decline further, and a decline below that level could be expected to reverse back toward 780 fairly quickly. Further down, but very unlikely at this point from my perspective, the 700 level on the S&P 500 would represent the lowest 10% of historical valuations, 625 would put the market in the lowest 5% of valuations, and anywhere at 600 or below would put the market in the lowest 1% of historical valuations. I don't expect to see such a level, but there it is. Note that these estimates are unaffected by how low earnings might go next quarter or next year. Stocks are not a claim on next quarter's or next year's earnings – they are a claim on an indefinite stream of future cash flows.

Recent market conditions seem like they have no precedent only because so many investment professionals know only the data they've lived through. If one actually examines market data from the Great Depression, 1907, and other less extreme panics, one realizes how much the recent decline has already discounted potential economic negatives. At this point, further declines in stock prices simply increase the long-term returns that investors can expect over time. We can't rule out the possibility that investors could get more frightened, or that they might abandon their stocks at prices that would offer extremely high long-term returns to the buyers. It is important to establish exposure slowly, but long-term investors who ignore attractive valuations are not investors at all.
