S&P Volatility Falls Most Since FDR as Valuations Sink

Daily price changes in the Standard & Poor’s 500 Index are decreasing the most in eight decades, shrinking to the smallest since 1995 when investors abandoned stocks just before the biggest rally ever.

The benchmark gauge for U.S. equities has gained or lost an average 0.46 percent a day this year, compared with 1.04 percent in 2011, the biggest reduction since 1934, during the Great Depression, according to data compiled by Bloomberg. Swings are diminishing after valuations fell 40 percent and correlation among shares weakened the most in at least three decades.
