What happens when rising inflation meets a surging stock market – and neither backs down?
As May begins, investors are caught between two conflicting signals: a more cautious Federal Reserve and a market that refuses to slow. The question is no longer just about interest rates, but whether traditional strategies like “Sell in May” still make sense in today’s environment.
The Fed’s “Bad News”: Inflation Risks Intensify
Recent economic data has triggered fresh concern inside the Federal Reserve.
Austan Goolsbee described the latest inflation figures as “bad news,” warning that the path to the Fed’s 2% target is becoming increasingly difficult.
The Personal Consumption Expenditures price index (PCE) – the Fed’s preferred measure of inflation – rose at an annual rate of 3.5% in March.
Several forces are driving this trend:
- Rising energy costs: Oil prices have surged in recent weeks, partly linked to geopolitical tensions involving Iran.
- Service sector pressure: Inflation remains “sticky,” even in sectors typically less exposed to tariffs.
- Supply shocks: Central banks such as the European Central Bank and the Bank of England are also warning about ongoing supply-side disruptions.
A House Divided: The Most Contentious Fed Meeting Since 1992
Internal divisions within the Fed are becoming more visible. At the latest policy meeting, officials voted 8-4 to keep interest rates in the 3.5%-3.75% range – the most divided decision in over three decades.
The disagreement went beyond the rate itself. Three officials opposed forward guidance suggesting that the next move could be a rate cut.
Goolsbee noted that such a split makes it harder for the Fed to communicate clearly with markets.
At the same time, leadership uncertainty is adding another layer of complexity. Kevin Warsh is preparing to take the chair, while current Chair Jerome Powell is expected to remain on the board as a governor – a move described as “judicious.”
Debunking the “Sell in May” Myth
While the Fed signals caution, equity markets continue to rally. This raises a key question: does “Sell in May and go away” still work?
According to data from Deutsche Bank and JPMorgan, blindly following this strategy may lead to missed gains:
- S&P 500 performance: Over the past decade, the S&P 500 has averaged gains of 1.5% in May, 1.9% in June, and 3.4% in July.
- European markets: Analysis of the STOXX 600 shows that “Sell in May” underperformed a simple buy-and-hold strategy in 25 of the last 39 years.
- Recent momentum: April was a standout month, with Italy’s FTSE MIB rising nearly 9%, while the DAX and Nasdaq posted some of their strongest performances in years.

Strategic Outlook for Investors
A hawkish Fed and a bullish stock market rarely coexist without tension – and this summer may be no exception.
While geopolitical shifts and potential de-escalation in the Middle East could support equities, the underlying composition of inflation remains a key risk.
The takeaway is clear: in 2026, rigid seasonal strategies may matter less than adaptability.
Investors who stay flexible – rather than relying on clichés – may be better positioned to navigate a market defined by both opportunity and uncertainty.
