Should You Sell Stocks in May? Here's What History Says.

The article argues that the old "Sell in May" adage is not supported by recent market data, citing an average S&P 500 return of 1.5% in May and 1.9% in June over the past decade, with gains in every May over the last five years. It also notes the S&P 500 rose 10% in April after easing geopolitical concerns and stronger AI-related earnings. The piece is mainly a market-timing commentary and long-term investing reminder, so its direct market impact is limited.

Analysis

The real signal here is not the calendar effect; it’s that the market has just emerged from a sentiment reset and is now facing a positioning problem. When a broad tape rebounds after a weak Q1, systematic and discretionary managers often chase strength into early summer, which can mechanically extend rallies even if macro data are mediocre. That makes the next 4-8 weeks less about seasonal averages and more about whether earnings breadth can broaden beyond the AI complex.

The biggest second-order implication is for JPM and the financials: if “sell in May” logic keeps retail sidelined while institutions rotate into high-quality cyclicals on pullbacks, banks can become quiet relative winners because they benefit from improved risk appetite, flatter volatility, and higher secondary issuance/M&A activity. JPM is also the cleanest barometer for whether this is a healthy rotation or a narrow tech-led squeeze; a stable JPM alongside firming rates would support a summer risk-on regime, while weakness there would suggest the rally is running on fumes.

NVDA remains the key momentum engine, but the setup is increasingly binary over a months-long horizon: upside requires evidence that capex converts into monetizable demand, not just enthusiasm around infrastructure spend. INTC is the contrarian beneficiary if the market starts rewarding “picks-and-shovels plus domestic supply-chain optionality” over pure AI beta; any disappointment in hyperscaler capex cadence could trigger a relative rotation into laggards with lower expectations. NFLX is the least exposed to the seasonal debate and functions more as a defensives-in-growth proxy if investors decide to stay invested but de-risk the most crowded AI names.

The consensus miss is that the seasonality debate itself can create its own flow-based opportunity: if investors believe May is weak, they sell too early and miss the strongest risk-adjusted entry point of the quarter. The risk to that view is a genuine macro shock over the next 1-2 months — inflation re-acceleration, dovishness reversal, or geopolitics — which would hit crowded growth exposure first and invalidate the rebound quickly.

Key Decisions for Investors

• Maintain a core long JPM position for 4-8 weeks as a relative winner from risk appetite and capital-markets activity; add on any 3-5% drawdown, with a stop if financials underperform the S&P 500 by more than 300 bps over two weeks.
• Trade NVDA vs INTC: long NVDA / short INTC in a 1:1 dollar pair for the next earnings cycle if AI capex commentary stays firm; target 8-12% relative upside, but cover if hyperscaler guidance softens or INTC closes the valuation gap via catalyst-driven upside.
• Use NFLX as a de-risked growth proxy: initiate a small long on market pullbacks if the goal is to stay invested without taking full AI-beta exposure; upside is steadier 5-8% over 1-2 months with lower event risk than semis.
• Fade the seasonal sell-off narrative via short-dated SPY put spreads only after a weakness day rather than preemptively; the edge is in collecting elevated implied volatility if investors overpay for a May correction that never materializes.
• If breadth narrows and JPM rolls over while NVDA continues higher, rotate from beta longs into a JPM/NVDA pair trade only if the market starts rewarding earnings quality over narrative; this is the cleanest tell that the summer rally is becoming fragile.
