The traditional investment adage 'sell in May and go away' may not hold true this year, as the S&P 500 has rebounded nearly 10% in just 11 trading sessions following a selloff due to global oil supply disruptions. Historically, the May-October period has yielded a lackluster average gain of 2% since 1945, compared to nearly 7% from November to April. However, the past decade has seen a stronger 7% average return during the summer months, including a remarkable 22.1% rise last year. Analysts suggest that investors who remained in the market since May 2016 would have seen their investments grow to about $34,000 from an initial $10,000, significantly outperforming those who followed the sell-in-May strategy. Factors supporting a bullish outlook include strong corporate earnings and economic resilience amid geopolitical tensions, particularly concerning the U.S.-Iran conflict. However, caution is advised as the upcoming midterm elections in 2026 have historically led to declines in the S&P 500 during the May-October period. Despite these concerns, the market's momentum could help it overcome seasonal challenges.
