Original Reddit post

Author presents long-run Testfolio backtests of US equities, cash, treasuries, gold and international stocks by presidential party, concluding US equities delivered positive real and excess returns regardless of which party held the White House, while explicitly warning the political split is not an allocation signal.

SPY — LONG The author's backtest data (1926-present, using SPYSIM/US series) shows US equities compounded about +10.3% annually versus roughly +3.3% for cash and +2.95% inflation, holding across both Republican and Democratic administrations. The stated mechanism is simply long-horizon equity compounding delivering positive nominal, real and above-risk-free returns. The author explicitly caveats that this is historical data, that past performance does not indicate future results, and that the party-based differences are correlation rather than causation.

Regardless of which party was in office, you would have generally done well to stay invested in US equities on a nominal, real, and risk-free premium basis.
