The October/November "Power Period"

Key points:

• A 5-day period encompassing late October into early November has shown a long-term tendency to be favorable for stocks
• This period has significantly exceeded the average 5-day performance over the past 77 years
• A long position in S&P 500 futures or an S&P 500 ETF (SPY or VOO) is the purest play

The October/November Power Period

For the record, "Yes," I know phrases like "Power Period" are hokey and borderline sensationalistic. But still, as a title, I think it has a little more pizzazz than, say, "A Period When the S&P 500 Has Gone Up 73% of the Time."

The period we will examine is the 5-trading-day period that extends:

• From the close of the 3^rd to the last trading day of October
• Through the close on the 3^rd trading day of November

In plain English, we are talking about being long the S&P 500 Index during the last two trading days of October plus the first three trading days of November.

For 2026, this period will extend from:

• The close on October 28th
• Through the close on November 4th
