The CNN Fear & Greed Index

The CNN Fear & Greed Index showed a notable improvement in investor sentiment during the latest week, rising to 45 (Neutral) on October 9, up from 31 (Fear) on October 2. This marks a shift away from the persistent fear that dominated September and early October, when readings ranged from 29 to 42, following Greed readings of 64 and 65 in early and mid-August. Sentiment gradually deteriorated through late August and September before rebounding over the past week, suggesting that investor anxiety may be easing. However, the index remains well below its August highs, indicating that confidence has not fully recovered.


The Quant Model Portfolios had an off week with the SPMO (S&P 500 Momentum ETF) sliding -1.4%. The Portfolios remain full of highly ranked stocks in the Quant universe and when Risk On becomes dominant again, I expect the Portfolios will lead the way up.

Midterm Elections and the Stock Market: What History Shows

Historical data suggests that U.S. stocks have generally performed well following midterm elections, regardless of which party gains or loses control.

Strong Post-Midterm Performance

Since 1950, the S&P 500 has risen in all 19 twelve-month periods following midterm elections—an unusually consistent historical record that spans recessions, wars, oil shocks and financial crises. Looking further back to 1938, the index has gained in roughly 95% of the 12-month periods following midterm elections, while the S&P 500 has historically averaged about a 6.3% gain during the first three months following a midterm election.

Divided Government Has Often Been Market-Friendly

Markets have sometimes viewed divided government favorably because political gridlock can make sweeping tax increases, regulatory changes and major spending initiatives more difficult to implement. Historically, the S&P 500 has often produced stronger median returns under certain forms of divided government, although research on the relationship between political control and stock returns is mixed. In fact, some academic studies have found that unified governments have produced higher excess stock returns than divided governments, challenging the simple idea that “gridlock is always good for stocks.”

Not All Political Outcomes Perform the Same

The historical record also suggests that the specific combination of political control matters. For example, periods featuring a Republican president and full Democratic control of Congress have historically produced somewhat weaker short-term S&P 500 returns than the broader post-midterm average. However, these differences are relatively small compared with the many other factors influencing stock prices.

The Bigger Drivers Are Usually Economic

Investors should be cautious about attributing market performance directly to election results. Inflation, Federal Reserve policy, interest rates, economic growth, energy prices and recession risks have historically played a much larger role in determining market performance than which party controls Congress or the White House.

Bottom Line for Investors

The historical message is encouraging: the stock market has generally performed well during the year following midterm elections, including periods when government became divided. However, the data represents historical correlation—not a dependable forecasting tool. Investors should focus less on predicting the political outcome and more on the economic and market conditions that ultimately drive corporate earnings and stock valuations.
