3 Best Trading Months
JANUARY: Absolutely our favorite month as the "January Effect" takes place. The "January Effect" is essentially buying in stocks that were heavily sold for tax loss reasons at the end of the year. This is especially true in small caps and speculative stocks. January is also often a very strong month for the markets as post holiday sales figures are released. Even in a bear market, January will always provide us with a strong performance.
JUNE: Summer doldrums? Not a chance. June is typically the month traders try to make enough to compensate for the doldrums of late July and August. More importantly, it is Russell re-constitution, and positioning in small caps prior to the institutional buying that occurs when new stocks are added to the Russell 2K can result in exceptional short term percentage gains.
NOVEMBER: Typically, October is the worst month for the markets, and November is a rally month as the "Santa" rally begins and mutual fund tax loss selling is over since their fiscal years typically end October 31. Market lows are often set in October, with rallies out of those lows in November.
