Why a Bounce on a Friday is Encouraging

Friday saw the market bounce after several indices closing at multi-month lows on Thursday. Fridays are interesting in that they are the least likely day of the week for a selloff to end or a rally to begin. But when rallies do start on a Friday, they have shown the best odds of success of any day of the week. I’ve seen this a number of ways over the years. The study below is one simple way to look at it. It examines times the market closed up the day after closing at a 21-day low the day before. Results are broken down by day of the week, and also by holding period.

Bounces by day of week

Looking out 10,15,20, and 25 days, Friday has the best stats of any day. And in most cases, none of the other days are even close. So if you are looking for an encouraging intermediate-term sign based on Friday’s action, this appears to be one.
