Much better than Shiller's new book, April 20, 2000
Smithers and Wright have written a very compelling indictment of today's stock prices. They argue that prices are way too high by historical standards, and exhort us to SELL. This is the same conclusion reached by Yale Professor Robert Shiller in his new book "Irrational Exuberance"; however, Smithers and Wright are much more convincing.Smithers and Wright use as a measure of valuation for stocks a statistic called "q" (or Tobin's q, named after Nobel laureate and Shiller colleague James Tobin). q represents the value of equities divided by the cost of replacing the underlying capital stock. So you might expect the stock market to be worth somewhere near q=1, where companies are worth what it cost to build them; historically, the average value of q is near 1. Smithers and Wright show that changes in q and equity prices are almost identical, since the cost of replacing the capital stock changes so little. They also show that high values of q are associated with terrible subsequent returns. They show how a simple strategy of selling when q rises to 1.5 and buying again when q falls below 1 * trounces * a buy-and-hold strategy. And they top it all off by showing that today's level of q, around 2.5, is unprecedented. So SELL! The reason the book is so much better than Shiller's is that Smithers and Wright give a coherent, fact- and theory-based argument for why q should be used to value stocks, not just P/E, stock earnings yield compared to bond earnings yield, or other popular measures. Shiller just used P/E and told us to sell due to today's high P/E; he did not even consider, not to mention try to debunk, other theories of valuation. Smithers and Wright point out, for example, that in the early '30s, P/E was very high due to the depressed depression-era profits of companies, but that q was very low, providing the buy signal of a lifetime that would have been missed by looking at P/E alone. The only negatives of this otherwise excellent book are: (1) Like most finance books, this one would gain from adding computations of after-tax returns, which shift us away from fancy trading strategies and towards buy-and-hold in taxable accounts. (2) They should admit that there are significant differences between today's economy and economies of the past. For example, in an economy such as ours where intellectual property is paramount and provides barriers to entry, firms' values may stay above the cost of replacing capital.

A valiant effort to rationalize a poor metric....., August 10, 2000
Smithers and Wright tell us they have undertaken a statistical study of the relationship between the market value of US equities and the net worth of the underlying firms (as expressed by the ratio known as "Tobins q") and that their analysis reveals a strong tendency for this ratio to revert to its long-run mean of .65. As Tobins q is currently measuring in the area of 1.5, the authors conclude that the US stock market is overvalued and likely to decline by more than 50%. Based on about 100 years of data, the authors provide an estimate (using confidence intervals) of how soon this mean reversion is likely to occur.The best service Smithers and Wright have provided in VWS is in demonstrating that contrary to popular wisdom (and books by other authors), a "buy and hold" approach to investing in the stock market has not necessarily provided a sure path to riches (or even a comfortable retirement). How well an investor has done depends crucially on, 1) what year he/she began investing in stocks, 2) the duration over which he/she invested, and 3) the year in which he/she retired. Over many periods, investors would have earned a much higher risk-adjusted return by holding bonds or cash instead of stocks. Thus, the authors conclude that with stocks set to decline by over 50% in the near future, any investor with less than, say a twenty year time horizon, would be well-advised to sell their stocks now. Of course, Tobins q only serves as a reliable indicator of future stock market performance if the factors responsible for its accuracy in the past are still valid today. Some of the other reviewers here have done a good job of pointing out the problem with measuring corporate net worth exclusively in terms of real assets. If US corporations were to capitalize (rather than expense) all of their investments in intangible assets, net worth would be significantly higher and Tobins q would not appear quite so top-heavy. Smithers and Wright attempt to discredit this point by suggesting that for every firm that adds value to its balance sheet (through intangible assets that perform well), there is another firm that destroys value (through intangibles that perform poorly). Thus, their argument goes, in the aggregate corporate net worth is no higher than what is reflected by real assets in the denominator of q. The problem with this defense is that one could logically make the same argument for real assets. For every factory or machine tool that adds value to a company by contributing to profits, there is probably a factory or machine tool at another firm which contributes to loss making. The logical (but absurd) conclusion of this line of reasoning is that in the aggregate, the real net worth of US corporations is ZERO. Smithers and Wright are supposedly economists by training but they have forgotten the first rule of economic valuation: sunk costs are irrelevant. The reason Tobins q is unlikely to accurately predict fair value in the stock market is that intrinsic value is not calculated by adding up total net assets but rather by discounting to the present time, the future cash flows which those assets can be expected to produce. Clearly, today's investors in the US stock market believe that is a very large figure indeed. Perhaps for their next book, the authors can assess the probability that these expected cash flows will actually materialize. That would tell us whether or not the stock market is overvalued and if so, by how much.

Scary Stuff, January 16, 2001
Smithers and Wright have undertaken an exhaustive 100 year study of U.S. equity prices using Tobin's Q as their primary metric. Tobin's Q is defined as Value of Stock Market/Corporate Net Worth. Their analysis shows that as of the end of 1998, the U.S. stock market was overvalued by about 2 ½ times - the greatest margin in history. This is scary stuff, particularly for the legions of individual investors in the United States that have rushed into the stock market in recent years, and have a naive faith that they should get a God given 20% return per annum compounded. Although the NASDAQ is now down 50% from it's March 2000 highs, it is still above that December 1998 value discussed by Smithers and Wright, as is the DOW. Thus, their warnings are as pertinent as ever. Smithers and Wright do a good job of taking the reader through various historic tests of Tobin's Q, comparing it to other measures of stock market valuation, such as PE ratios and the dividend yield. They show that Tobin's Q is a better measure of valuation. Their writing is straightforward and accessible to the general reader. Their message is compelling and extremely valuable. Their main conclusion, which psychologically will be very hard for most readers to accept, is that the best thing that most investors can do right now is to get out of the stock market altogether and wait until valuations return to more reasonable levels (their analysis suggests that a 50% decline in the DOW is quit possible). Smithers and Wright show that a "go to cash" strategy would have worked in the past and they do a good job of explaining why it will not be any different this time around. The book is must read for any individual investor. My only criticism is that they take too long to make their points. A book of half the length would have been appropriate.
