Trading the US Election: A Short-Term S&P 500 Event Strategy

Summary

The article examines whether US election dates coincide with unusual S&P 500 returns. It describes aligning historical index returns to the nearest election, grouping observations by days before or after election day, and comparing average returns across the event window. It also proposes checking whether the pattern persists across time, differs between midterm and general elections, or varies with the eventual winner.

The suggested trade is to increase S&P 500 exposure five days before an election and remove that extra exposure one day afterward, using instruments such as equity index futures or an ETF. The article frames elections as periods that may bring stronger return trends, higher risk premia, and expensive implied volatility. However, the supplied text gives no charts, sample counts, return estimates, or statistical tests to substantiate the proposed effect. The strategy is therefore presented without enough evidence here to judge its robustness, risk-adjusted performance, or usefulness beyond the historical sample.

Key ideas

• The analysis aligns S&P 500 daily returns to the nearest US election date.
• Average returns are grouped by relative day to look for an event-related pattern.
• The proposed position increases index exposure five days before an election and removes it the following day.
• The text suggests checking stability over time and differences by election type and winner.
• No supporting performance figures or statistical tests are included in the supplied article text.
