Monthly Futures Seasonality, May 2024: Sell in May and Go Away?

Sell in May and go away? Not so fast.

• April proved to be a massive disappointment f for U.S. equity markets.
• May is a bullish month for the S&P 500.
• It's a bearish month for Treasury notes.

After five consecutive months of gains, April proved to be a massive disappointment from a seasonal perspective for U.S. equity markets.

At one point in April, the Nasdaq 100 erased all its gains year-to-date, if only to underscore how poorly price action unfolded despite the promising historical backdrop. 

The bull market might be still alive

That said, historical price data still suggests that the bull market may not be dead yet. April marked the end of a five-month winning streak. Since 1950, there have been 30 prior instances of five green months failing to continue the rally into a sixth month.

On average, one month later, the S&P 500 was higher 73% of the time for a gain of 1.9%; three months later, the S&P 500 averaged a gain 3.9%, rallying 83% of the time. The correction seen in April is not unique and does not necessarily suggest that a new bear market has begun, if history is any sort of guide.

What about "sell in May and go away," the popular axiom peddled by financial media? It’s a fun turn of phrase, but nothing more. The May-July window has produced positive returns over the past 10 and 20 years for both the S&P 500 and Nasdaq 100. The appropriate catchphrase should be "buy through July."
