The best election-year stock market in decades is about to get choppy

History suggests volatility will spike in the final weeks of the Trump-Harris presidential showdown.

Good morning! The S&P 500 hit its 46th record high of the year Monday.

Historically, the index takes 709 trading days to reach its bull-market high, according to market data cited by the Wall Street Journal.

This current bull run is just over 500 trading days young — and the presidential election actually suggests more upside ahead

Volatility defines election-year markets

Markets prefer stability over surprises.

It’s no wonder stock market history suggests volatility is about to ramp up.

Changes to White House policy, economic strategy, and regulations can fuel jitters among traders. Markets have reflected those uncertainties for just about every election year dating back decades. 

“We’re now heading into the second half of October when volatility tends to rise in election years,” Morgan Stanley strategist Mike Wilson told clients Monday. 

The CBOE Volatility Index (VIX) — also known as Wall Street’s fear gauge — tracks the volatility of the S&P 500.

On Monday, it hovered just below 20. 

At the start of August it had spiked to levels only seen during 2008 and at the start of the pandemic.

Across the previous eight presidential elections, the monthly VIX averaged 20.7 during election years, above the 19.4 seen in non-election years, according to data from Stifel. 

This year, the VIX since the start of September has averaged 18.6. 

Notably, the September-to-October stretch of election years has seen the VIX increase by an average of 25%.

Meanwhile, the VIX has declined in that period during non-election years.

Historical data suggests the VIX will keep climbing in the coming weeks before seeing a sharp drop-off after the election, as the following charts from Morgan Stanley illustrate.

What about stock performance? 

While the S&P 500 has seen its best election-year performance since 1936, investors remain split on which political outcome would be the best for portfolio returns. 

Some Morgan Stanley clients consider a Republican sweep — less regulation, extended tax cuts — as the best scenario for stocks.

Others view a Trump victory plus a gridlocked Congress as a better result, as it would limit fiscal expansion. 

“There is also a contingent that sees a Harris win with a divided Congress as the best scenario for stocks,” Wilson said.

“The thinking among this group is that this outcome would still yield a tax cut extension but would not introduce tariff risk to the growth backdrop in a meaningful way.”

Taking a six-month outlook, Morgan Stanley considers a split scenario better for stocks compared to a sweep.

Either way, the S&P 500 tends to perform better in the six months after an election compared to the six months before one. 

As you might suspect, however, trying to pin down stock returns by sector or name gets trickier. 

“There’s no repeatable pattern of individual sector winners and losers during election years,” Stifel analysts wrote in a recent note. “That said, consistent with the broader index analysis, all sectors tend to be higher 12 months after the election.”
