TAKEAWAYS
- “Promote in Might” is much less about weak point within the spring and extra about weak point within the autumn months.
- For the reason that COVID low, the S&P 500 has often been fairly robust in Might-June-July.
- We’re watching the SPX 5750 degree together with different indicators to validate a possible seasonal reversal.
We have all heard the traditional market maxim, “Promote in Might and go away.” For a lot of buyers, that is the introduction to market seasonality that means a six-month interval the place it is simply greatest to keep away from shares altogether.
Via my very own expertise, complemented with interviews with seasonality specialists like Jeff Hirsch of the Inventory Merchants Almanac, I’ve discovered to deal with seasonal patterns as tendencies as a substitute of certainties. Seasonal patterns let you know what’s prone to occur, barring any exterior forces that may trigger the markets to deviate from their regular seasonal patterns.
“Promote in Might” is Actually About Weak point in Autumn
We are able to use the seasonality charts on StockCharts to try to determine patterns going again via years of market historical past. We’ll begin with 20 years of information, from 2005 to 2024. Every bar represents the p.c of the observations the place the month ended larger than it started. The numbers discovered on the backside of every bar reveals the typical return for that calendar month based mostly on the years in query.
Going again for the final 20 years, we are able to see that the March-April-Might interval is definitely pretty robust. These months have been up 75-80% of the time, representing probably the most constant three-month interval of all. However did you discover how the following 5 months, except a fairly robust July, are principally the weakest a part of the yr?

It seems that the rationale why “promote in Might” has usually labored out is much less about Might being tremendous weak, however extra about how main lows have often come within the fall months. For the reason that COVID low in early 2020, we have skilled main lows in September or October yearly apart from 2024.
Spring and Early Summer season Have Been Loopy Sturdy
Once we give attention to the final 5 years, we are able to see that the Might-June-July interval has been constantly robust. The truth is, Might and July have seen bullish developments yearly since 2019. So, whereas buyers usually speak in regards to the “summer season doldrums” and weak point into the recent summer season months, the latest proof would recommend in any other case.
The weakest months because the COVID low have really been January, February, September, and October. So once more, it has been much less about weak point within the spring, and far more about weaker worth motion into the normal low in September or October. Additionally be aware the energy in November, the place the market is sort of at all times rallying off a serious low and organising for a optimistic end to the calendar yr!
Will 2025 Observe the Regular Seasonal Sample?
As I discussed earlier, I like to think about seasonal patterns as tendencies. There is no such thing as a assure that July will probably be robust, and there’s no approach I can let you know for certain that the market will make one more main low in September. Seasonality tells you the overall bias to the markets, however aware buyers know an important proof is worth itself.
Given the acute rally off the early April low, we have seen a fast rotation from bearish sentiment to extra bullish outlooks as buyers have began to imagine within the new uptrend section. This week’s worth hole larger for the S&P 500 may present an ideal assist vary to watch within the coming weeks and months.
If the S&P 500 is ready to maintain 5750 and stay above the assist vary set from the hole earlier this month, then maybe the fairness markets will comply with the identical sample as latest years and stay robust into August. If, nevertheless, the S&P 500 is unable to carry this key assist vary, and we additionally verify that breakdown with weaker momentum readings and deteriorating breadth situations, then the S&P 500 could also be charting a brand new course via what has develop into a robust interval within the calendar yr.
