These Stocks and ETFs Can Beat the ‘Sell in May’ Slump — and Dodge the 2026 Midterm Blues

Why It Matters

Midterm‑driven volatility can erode returns for cash‑seeking investors; defensive sector exposure offers a smoother performance path during the summer months.

Key Takeaways

• Sell‑in‑May strategy historically underperforms during U.S. midterm election years
• Defensive sector ETFs outperformed broad market from May to October 2026
• Utilities, consumer staples, and health‑care stocks showed lowest volatility this summer
• Investors can avoid cash drag by rotating into sector‑focused ETFs

Pulse Analysis

Seasonal market patterns have long guided portfolio timing, with the “sell in May, buy in October” mantra rooted in the historically weaker summer performance of equities. Recent data, however, suggests that the rule of thumb needs refinement during U.S. midterm election cycles. Historically, midterms increase political uncertainty, prompting investors to shy away from riskier growth stocks, which depresses the S&P 500 more than usual. By recognizing this nuance, savvy investors can adjust their seasonal playbooks to mitigate downside risk without fully exiting the market.

Defensive sectors—particularly utilities, consumer staples, and health‑care—have demonstrated resilience in past midterm summers. Their earnings are less sensitive to economic cycles, and they often benefit from steady demand, making them attractive when broader sentiment sours. ETFs such as XLU (Utilities), VDC (Consumer Staples), and XLV (Health Care) have consistently posted lower volatility and modest outperformance versus the S&P 500 from May through October in election years. This sector rotation not only preserves capital but also captures dividend yields that cash equivalents typically lack, enhancing total return potential during the six‑month lull.

For investors seeking to implement this strategy, the key is disciplined reallocation rather than speculative timing. Allocate a modest portion of the portfolio—perhaps 15‑20%—to defensive ETFs before May, then gradually shift back to growth‑oriented holdings as the political landscape stabilizes in the fall. Monitoring election‑related policy developments can fine‑tune sector weightings, while maintaining a core diversified base guards against sector‑specific shocks. This balanced approach offers a pragmatic path to sidestep the summer slump and position the portfolio for a stronger post‑election rally.
