“History repeats - the argument for abandoning prevailing valuation methods regularly emerges late in a bull market, and typically survives until about the second down-leg (or sufficiently hard first leg) of a bear. Such arguments have included the ‘investment company’ and ‘stock scarcity’ arguments in the late 20's, the ‘technology’ and ‘conglomerate’ arguments in the late 60's, the nifty-fifty ‘good stocks always go up’ argument in the early 70's, the ‘globalization’ and ‘leveraged buyout’ arguments in 1987 (and curiously, again today), and the ‘tech revolution’ and ‘knowledge-based economy’ arguments in the late 1990's. Speculative investors regularly create ‘new era’ arguments and valuation metrics to justify their speculation.”
- John P. Hussman, Ph.D., New Economy or Unfinished Cycle?, June 18, 2007. The S&P 500 would peak just 2% higher in October of that year, followed by a collapse of more than -55%.
“Old ways of valuing stocks are outdated. A technological revolution has created opportunities for continued low inflation, expanding profits and rising productivity. Thanks to these factors, the United States may be able to enjoy an extended period of expanding stock prices. Jumping out now would leave you poorer than you might become if you have some faith.”
- Los Angeles Times, May 11, 1999. While it’s tempting to counter that the S&P 500 would rise by more than 12% to its peak 10 months later, it’s easily forgotten that the entire gain was wiped out in the 3 weeks that followed, moving on to a 50% loss for the S&P 500 and an 83% loss for the tech-heavy Nasdaq 100..
“Stock prices returned to record levels yesterday, building on the rally that began in late trading on Wednesday... ‘It’s all real buying’ [said the head of index futures at Shearson Lehman Brothers], ‘The excitement here is unbelievable. It’s steaming.’ The continuing surge in American stock prices has produced a spate of theories. [The] chief economist of Kemper Financial Services Inc. in Chicago argued in a report that, contrary to common opinion, American equities may not be significantly overpriced. For one thing, [he] said, ‘The market may be discounting a far-larger rise in future corporate earnings than most investors realize is possible, [and foreign investment] may be altering the traditional valuation parameters used to determine share-price multiples.’ He added, ‘It is quite possible that we have entered a new era for share price evaluation.’”
- The New York Times, August 21, 1987 (the S&P advanced by less than 1% over the next 3 sessions, and then crashed)
“The failure of the general market to decline during the past year despite its obvious vulnerability, as well as the emergence of new investment characteristics, has caused investors to believe that the U.S. has entered a new investment era to which the old guidelines no longer apply. Many have now come to believe that market risk is no longer a realistic consideration, while the risk of being underinvested or in cash and missing opportunities exceeds any other.”
- Barron’s Magazine, February 3, 1969. The bear market that had already quietly started in late-1968 would take stocks down by more than one-third over the next 18 months, and the S&P 500 Index would stand below its 1968 peak even 14 years later.
“The 'new-era' doctrine - that 'good' stocks (or 'blue chips') were sound investments regardless of how high the price paid for them -- was at bottom only a means for rationalizing under the title of 'investment' the well-nigh universal capitulation to the gambling fever.”
- Benjamin Graham & David Dodd, Security Analysis, 1934, following the 1929-1932 collapse
“The recent collapse is the climax, but not the end, of an exceptionally long, extensive and violent period of inflation in security prices and national, even world-wide, speculative fever. This is the longest period of practically uninterrupted rise in security prices in our history... The psychological illusion upon which it is based, though not essentially new, has been stronger and more widespread than has ever been the case in this country in the past. This illusion is summed up in the phrase ‘the new era.’ The phrase itself is not new. Every period of speculation rediscovers it.”
- Business Week, November 1929. The market collapse would ultimately exceed -80%.
