September Primer

You ever watch a TV show and the entire episode just talks about things that happened in previous episodes?

That's what this is. :D

S&P 500: A Primer For August & September


Statistically, September is the worst performing month of the year, with a 43% win ratio, and the worst average returns of all months. Thus (in times of uncertainty) August is a good month to decide how to be positioned for September.

Why?

The September low to the Dec close has a 90% win ratio, with an average-of-gains of 9.18%. Not that this is easy, but in theory if we could correctly time the Sep low (historically) we have a 90% chance of a 9.18% gain or a 10% chance of a -11.12% loss.

Below is September's close based on the August close. It may surprise you to know when August closes positive, September's stats are weaker.

The Twelve Months

The key takeaway: This next chart is a consolidation of the previous three. Generally speaking, there’s been a universal 63-year-specific truth. The months of Feb, Jun, & Sep might be a good time to take some risk off, particularly if the market's conditions are already not good.
