The bull market for stocks turns six; the numbers behind the rise

The bull market has turned six, one of the longest runs for stocks since the 1940s.

The Standard & Poor's 500 index has more than tripled since March 9, 2009, when it bottomed in the wake of the financial crisis and recession that followed.

Since the end of World War II there have been 12 bull markets, with the average run lasting 58 months, according to S&P Capital IQ. At 72 months, the current streak is the fourth longest in that period. The longest streak started in 1990 and stretched 113 months into 2000.

Here are some of the numbers behind the stock market run:

APPLE'S GROWTH:

— $737 billion: The current market value of Apple, the world's most valuable publicly traded company.

— $94.8 billion: The market value of Apple at the start of the bull run in 2009.

WHAT INVESTORS GOT:

— 25 percent: The average annual return for the S&P 500 during the last six years (measured from March to March).

BIGGEST WINNER:

— 7,544 percent: The gain for real-estate investment trust company General Growth Properties is the biggest for any stock in the S&P 500 during the bull run.

BIGGEST LOSER:

— 67.8 percent: The drop for Transocean, a company that provides drilling services for oil and gas wells, is the biggest decline of any S&P 500 company.
