Happy Memorial Day! The week of Memorial Day has shown some interesting seasonal tendencies over the years. But it has faltered greatly the last few. The chart below is one I have shown in the past, and have now updated. It examines S&P 500 performance from the Friday before Memorial Day to the Friday after it.
There was no substantial edge apparent throughout the 70s, but starting in 1983 through 2009 there was a bullish tendency. The last 8 years this week has mostly struggled. That said, Thursday continues to look seasonally strong, and I will update that study later this week.
