Despite reporting record profits, market valuations for U.S. equities have been well below its 50-year average for one of the longest periods since 1973, reports Bloomberg.

Anxious investors
Of the $37 trillion erased from global equities in the credit crisis, $24 trillion has been restored, reports Bloomberg. But it has taken a long time to get even this far, and investors are still discouraged.

"After two significant bear markets, the flash crash and the lost decade, many have simply said, 'No mas,'" said Howard Ward of Gamco Investors in an email on Jan. 24. "Of course, bull markets have a history of climbing a wall of worry. And it is happening again."

Sunny skies ahead?
The Standard & Poor's 500 index is now trading at 13.7 times profit. This is well below its mean ratio of 16.4, a number it hasn't traded above in 446 days.

Bloomberg refers to the decline as "part of a decade-long retreat in U.S. equity valuations since the S&P 500 peaked at 31.2 times earnings in December 1999."

But a quick history lesson may encourage investors to take note:

"The last two times the S&P 500 slumped below its historic average, equities rallied. The benchmark index is up 42 percent since it climbed above the five-decade mean in June 2009. It spent 14 months below the average level from August 1988 through October 1989 before quadrupling within eight years starting in October 1990."
