When is the best time to buy or sell stock?

In most cases, the price dips around noon but can rise towards the end of the day. The basic principle is to buy when low and sell when high.

Stock prices also tend to drop in the middle of the month. So you might benefit from timing stock buys near a month's midpoint - for example, 10th - 15th.

The best day to sell stocks would probably be within the five days around the turn of the month.
