Dec. 10 (Bloomberg) -- A global stock slump may have further to go, according to Tobin’s Q ratio, which compares the market value of companies to the cost of their constituent parts, CLSA Ltd. strategist Russell Napier said.
The ratio, developed in 1969 by Nobel Prize-winning economist James Tobin, shows the Standard & Poor’s 500 Index is still too expensive relative to the cost of replacing assets, said Napier. While the 39 percent drop in the index this year pushed equity prices below replacement cost, history suggests the ratio must sink further as deflation sets in, he said. The S&P may plunge another 55 percent to 400 by 2014, Napier said.
“The Q has come down to its average, however it’s not always stopped at the average,” said Napier, Institutional Investor’s top-ranked Asia strategist from 1997-1999. “It has tended to go significantly below that in long bear markets.”
Napier, who teaches at Edinburgh Business School and advised clients to buy oil in 2002 before it tripled, based his S&P 500 forecast on the Q ratio for U.S. equities as well as the 10-year cyclically adjusted price-to-earnings ratio, another measure of long-term value.
Before the trough in 2014, investors are likely to see a so- called bear market rally for the next two years as central bank actions delay the onset of deflation, Napier said.
“In the long run, stocks will become even cheaper,” said Brian Shepardson, who helps manage $1.9 billion at Xenia, Ohio- based James Investment Research. The firm’s James Balanced Golden Rainbow Fund beat 98 percent of similar funds this year. “There’s a likelihood of some type of rally and further pullback surpassing the lows we’ve already set.”
The Q ratio on U.S. equities has dropped to 0.7 from a peak of 2.9 in 1999, and reaching 0.3 has always signaled the end of a bear market, said Napier, 44, the author of “Anatomy of the Bear,” a study of how business cycles change course. The Q ratio for U.S. equities has fluctuated between 0.3 and 3 in the past 130 years.
When the gauge is more than one, it indicates the market is overvaluing company assets, while a Q ratio of less than one signifies shares are undervalued because it is cheaper to buy companies than to build them from the ground up.
At the end of the four largest U.S. bear markets in 1921, 1932, 1949 and 1982, the Q ratio fell to 0.3 or lower, and history is likely to repeat, said Napier. From the 1982 trough, the S&P 500 grew more than 14-fold to the middle of 2000, when Napier says the last bull market ended.
Federal Reserve Chairman Ben S. Bernanke’s indication that he will use “quantitative easing” to prevent deflation points to a stock market rally that may last for the next two years, Napier said. With quantitative easing, a tool pioneered by the Bank of Japan, central banks can stimulate inflation by printing money and flooding the market with cash in order to encourage consumers to spend.
The government’s efforts will eventually fail as ballooning government debt devalues the dollar, causes investors to flee U.S. assets and takes the S&P 500 to its eventual bottom in 2014, Napier said.
“Bear markets always end for exactly the same reason, and that is the market begins to price in deflation,” he said. “Equities will be incredibly cheap.”
