US Stock Seasonality Site

Came across this site that does some seasonality analysis on US stocks (only). Added it to the list of useful sites on the right panel.

Seasonality may play a part for some companies, due to seasonal earnings report (eg. christmas period for retailers), or due to dividend policies. Of course, do validate if these reasons for the seasonality factors are still relevant prior to taking position in the stock.
