Election 2024: What do the markets say?
Monica Guerra, Head of Policy, Morgan Stanley Wealth Management
09/11/24Summary: Certain economic indicators and stock market trends have historically forecasted which U.S. presidential candidate is likely to prevail. Here’s what investors should know.
Listen up.
If you’re hungry for more on this topic, listen to the Morgan Stanley Thoughts on the Market podcast, "US Election: A Game of Inches", where our Head of Fixed Income and Thematic Research, Michael Zezas, weighs the possible outcomes for investors as we move closer to Election Day.
The race to the White House continues to heat up as the major candidates hit the campaign trail to unveil key policy details and drum up support from voters. With polls showing Vice President Harris and former President Trump locked in a tight contest, investors may consider looking to economic indicators and stock-market trends for insight into potential election outcomes. Here’s what to know heading into a critical stretch just over two months before Election Day.
High prices and rates may sway voters
A recent analysis of several key economic indicators highlighted potential challenges for Democrats.
While not the only determinant, voter sentiment on the economy is correlated with presidential outcomes. For example, according to the Center for the Study of Democratic Institutions, a 5% increase in GDP results in a corresponding 6% gain in incumbent vote share.1
However, this dynamic has recently broken down for President Biden: GDP growth accelerated to a 2.8% annual rate in 2024’s second quarter, up from 1.3% in the first, yet Biden’s approval rating has dropped 1.4% this year.1
The disconnect may be due to voters’ perceived wealth, amid still-high prices and interest rates. A recent Morgan Stanley Research survey shows inflation and the economy are the top concern for 61% of consumers, even as inflation cools.
The pinch of higher prices, combined with interest rates that will likely remain high by historical standards, even after expected Federal Reserve rate cuts starting in September, may weigh on the Democratic nominee.
Consumer moods improve, but remain dim
The University of Michigan Consumer Sentiment Index increased for the first time since March to 67.8 on a preliminary basis in August, from 66.4 in July. Still, the index remained well below its historical election-year average of 85.7. In fact, going back to 1978, sentiment has only been this low in August of an election year twice, with one instance resulting in the incumbent’s unseating (1980) and the other in a party change in which there was no incumbent (2008)1. All that said, sentiment is just one of many indicators of election results and should be viewed in the context of overall economic conditions.
Analyzing consumer sentiment by political party, we unsurprisingly see higher readings among Democratic voters and lower readings among Republican voters, which is consistent with history, reflecting higher sentiment from those in favor of the sitting party in the White House.
- Sentiment fell slightly among Republicans from July to August but rose by 4.9 points among Democrats and 1.5 points among independents.
The recent rise among these latter cohorts may be due in part to voter enthusiasm around Harris entering the race. However, the index among independents remains closer to Republicans than that of Democrats overall.
Stock returns may reflect political shifts
- The performance of different equity sectors can also offer insight into potential political outcomes, as investors position their portfolios for gains or losses ahead of anticipated policy changes that may affect an industry’s profitability.
- Knowing this, Morgan Stanley Wealth Management’s Global Investment Office (GIO) created two equity baskets, each containing 12 sector and industry exchange-traded funds that could benefit from a Democratic or Republican win. The Republican basket (which includes sectors such as Energy, Materials, Utilities and Real Estate) had outperformed the Democratic basket (including solar energy, tech and infrastructure stocks) by 9% year-to-date, as of late August—down somewhat from the maximum spread of 10.2% in early August. The spread’s tightening came on the heels of Harris’ nomination, and sustained momentum for her candidacy could create risks for stocks favored in the event of a GOP victory.1

- We also looked at a Republican “short” basket, containing stocks that could perform poorly if the GOP candidate prevails. As of late August, it was down more than 18% year-to-date and lagged a comparable Democratic “short” equity basket by wide margins, indicating investors could already be hedging against a Republican win1.
Investors should keep in mind, however, that while these indicators may offer insight into sentiment at a given point in time, they are not predictive of actual outcomes, nor should they be viewed as an endorsement of any political party.
Investing in an election year
Of course, much can change between now and November. In the meantime, investors may want to watch for potential index-level gains—and possible turbulence—in the weeks ahead.
- On average, the S&P 500 has risen in election years, with the strongest gains occurring amid split control of Congress and the White House, as gridlock typically limits drastic policymaking.
- But market volatility also tends to rise in election years, and 2024 may be particularly bumpy given heightened geopolitical uncertainty and political polarization, among other factors.
Importantly, we remind investors that while political outcomes and corresponding policy shifts may impact company profitability, the business and economic cycle are likely to be more relevant to market performance.
Summary
- Amid still-high prices and interest rates, dim consumer moods may be a disadvantage for the democratic party’s presidential candidate.
- Equity-sector performance suggests—at least for now—that some investors may be positioning their portfolios for a GOP win.
- Election years tend to bring equity-index gains and market volatility, with 2024 expected to be a particularly bumpy ride.
- Investors should remember, however, that the business cycle is likely more relevant to market performance than electoral outcomes.
