Historically, the HUI and XAU indices tend to go up during midterm election years, making midterms the strongest period of the four-year presidential cycle for gold mining equities. [1, 2]
However, their specific seasonal behaviors split slightly: the HUI tends to hit its peak strength directly during the midterm election year, whereas the XAU often sees its strongest momentum carry into the post-election year.
Overview of Midterm Trends
Precious metals and gold stocks broadly interact with the political business cycle differently than the general stock market:
| Index / Asset | Performance Trend During Midterm Election Years |
|---|---|
| HUI Index (NYSE Arca Gold Bugs) | Strongest year of the cycle. Highly reactive to rising political uncertainty and market volatility. |
| XAU Index (Philadelphia Gold & Silver) | Upward trend, but historically behaves as a precursor to even stronger gains in the following post-election year. |
| Gold Bullion | Strongest year of the cycle, averaging an 11% to 12.5% return since 1968, heavily driven by an upward rally that begins in July. |
| S&P 500 / General Equities | Muted or negative through the first 3 quarters due to policy uncertainty, followed by a sharp post-election rally. |
Why Gold Stocks Gain Ground
The primary driver behind the upward movement of the HUI and XAU indices during midterms is investor risk aversion. Historical analysis of the Presidential Election Cycle notes that broader equity markets typically face high volatility and choppy, sideways action in the months leading up to a midterm vote. [1, 2, 3]
As geopolitical and domestic policy uncertainties peak, investors seek out safe havens. This dynamic regularly pushes gold prices higher—particularly in the second half of the midterm year—which serves as a major fundamental tailwind that expands profit margins and lifts the stock prices of the gold miners tracking the HUI and XAU. [1, 2]
