    U.S. Bancorp research highlights 1% short-term S&P 500 pullback in divided government

    Question

    U.S. Bancorp research highlights 1% short-term S&P 500 pullback in divided government

    Direct answer

    Analysis from U.S. Bancorp shows that divided government outcomes from midterm elections, specifically a Republican executive branch paired with a Democratic-controlled legislature, historically correlate with an average 1% decline in the S&P 500 over the subsequent three months. While legislative gridlock typically inhibits aggressive fiscal or tax policy shifts over multi-year horizons, short-term budget negotiations and appropriation deadlines introduce temporary equity market volatility. — bullish pressure on VIX.
