One of the few bright economists, Robert Schiller has proposed that in terms of long term valuations I.e. P/E's based on 10 year trailing as reported earnings' average, is a trustworthy indicators of future market trends. I happen to agree with this methodology.
The theory suggests that markets will revert to means once they extend beyond a certain range (irrational exuberance). Historically, this range has been between multiples of 10 and 22, with an average approximately at 13 to 14. Obviously, as market psychology will certainly play a large role, undershooting and overshooting are inevitable based on the sentiments of market participants.
Using a close current price of 700 on the S&P 500, a P/E of 13.21 is inducted based from 10 year smoothed earnings. This suggests the market is rather fairly valued. However, as referenced above, the psychology of the market can prevail in moving the indexes to extremes in either direction for a period of time. Considering the extreme pessimism and more importantly, uncertainty, this is nearly assured as a highly probable outcome in the present and future.
Using a multiple of 10 as a realistic 10 year average P/E at some point in the future, we can induct that the S&P 500 can reasonably drop in value to a level of 530 without any adjustments to earnings. That is a 32% drop from current index levels. Even more alarming is that the 10 year average as reported earning level will most likely continue to decrease as each quarter passes throughout 2009. And yet still more alarming is that investor psychology can move the market lower than a multiple of 10.
While the scenario in my previous paragraph doesn't necessarily have to unfold as outlined, there is a probability it may. However, given the vast amount of uncertainty in the markets, a scenario of consolidation from this point on may only move markets slightly lower,leaving for a range bound market for several years, possibly a decade or more (it has happened in the past) until the 10 year P/E is undervalued and investor optimism returns.
The variations of how the future may unfold are infinite. However, the probability that a still sharp fall in the S&P 500 is indeed not to be ignored, and neither should the second scenario. In either case, with no real boom like productive capacity in our economy and massive government intervention, I suggest a very high probability that despite a sharp fall in the S&P 500 could still unfold, there is no reason to expect a sharp reversal in trend to the upside for a sustained period of years, that is a secular bull market. Instead, I deduce a long term consolidation period of misleading ranges will be the likely outcome for some years to come. A buy and hold strategy will lose you money in the next decade.
