Seasonal Weakness

Somebody besides me discusses market seasonality.  Chart of the Day's take on seasonal weakness.

"The stock market is about to enter what has historically been the weakest half of the year. Today's chart illustrates that investing in the S&P 500 during the six months of November through and including April accounted for the vast majority of S&P 500 gains since 1950 (see blue line). While the May through October period has seen mild gains during major bull markets (i.e. 1950-56 & 1982-97), the overall subpar performance during the months of May through October is noteworthy. Hence the saying, 'sell in May and walk away."

*Long ETFs related to the S&P 500 in client and personal accounts although positions can change at any time without notice.
