Fall is generally a good time to buy stocks. A very high percentage of the historical gains of the stock market have come between Nov and April 1. This is the time of the year to be looking for a rally. Timing it is another discussion. However, assuming the circumstances are right at the time, approx. Nov. 1 is the seasonal low spot.
This year with the mid-term congressional election cycle, and a larger scale 4 year cycle supporting it, there is a good backdrop to look for a rally in stocks.
