This Rally In Historical Context


The B.I.G. blog always produces high quality research on the markets. This piece is about the magnitude of the stock market rally from the March lows put into historical context:

"It has been exactly nine months since the S&P 500 bottomed on March 9th at 676.53. Since then, the index has rallied 62%. Below we provide a chart of the rolling 9-month change (%) for the S&P 500 going back to 1928. As shown, 1933 was the only other time when the S&P 500 had a bigger 9-month gain. The 9-month period ending on May 12th, 1983 is the next best behind the current one with a gain of 60%. Also, the 9-month 62% gain was preceded by a 9-month decline of 51%. The only time that the index fell more over a 9-month period was in 1931/32 when it dropped 68%. " in Bespoke Investment Group Website

But this does not mean that the market has to sell off to correct itself. It can also go sideways and "correct" the extreme rolling 9-month change (%) on the S&P 500.
