Turn of the Month for September (Dow Jones – DIA)

We are approaching the end of September; historically, the end and beginning of a month have been positive.

  • We buy at the close on the last fifth trading day of the month, and
  • We sell at the close of the fourth trading day of the new month.

This is the equity curve:

The average gain per trade is 0.6%, the win rate is 64%, and max drawdown is 20%. We can also add that the CAGR was 7% vs. buy and hold’s 8.2%.

The above is for all months. What about September (and the first days of October)?

There are not many trades, but the average is lower than for the whole year: 0.49%.
