Keeping Your Portfolio Above the Political Fray
Highlights:
The Volatility Spike: A Common Pattern
As the 2024 US presidential election looms, investors find themselves caught in a familiar tug-of-war between political convictions and financial prudence. The siren song of partisan prognostication grows louder, tempting many to realign their portfolios based on anticipated electoral outcomes. However, a closer examination of historical data and recent market behavior suggests that such moves may be ill-advised.
It’s an established trend: market jitters often intensify around elections. The CBOE Volatility Index (VIX), often dubbed “the fear gauge,” has tended to spike in the weeks surrounding US presidential elections (Figure 1). This year appears to be no exception, with the VIX already having shown signs of pre-election nervousness.
But savvy investors would do well to look beyond these short-term fluctuations. Despite the quadrennial uptick in volatility, a broader perspective reveals a more reassuring picture.
Rising Tides Lift All Parties
Contrary to popular belief, markets have demonstrated a remarkable ability to climb higher regardless of which party occupies the White House. Over the past century, both Democratic and Republican administrations have presided over periods of robust stock market performance. This bipartisan bull run challenges the notion that one party is inherently “better for business” than the other (Figure 2).
Recession Fears: More Bark Than Bite?
Recent survey data from Nationwide’s annual Advisor Authority report paints a stark picture of partisan economic pessimism.1 Nearly one in three investors believe a recession is imminent if their less-favored party gains power in 2024. Yet, historical evidence suggests such fears are often overblown.
An analysis of presidential terms and corresponding market performance reveals a more nuanced reality. While it’s true that most administrations have seen significant market drawdowns — with only three presidents escaping “bear market” territory of 20% or more — the overall trajectory has remained positive across party lines (Figure 3).
United We Stand, Divided We… Still Grow?
That’s not to say politics are irrelevant to market performance. History indicates that periods of unified government — when one party controls the presidency and both chambers of Congress — have generally produced stronger returns compared to divided governments. However, the differential is not so dramatic as to justify drastic portfolio reallocations based on predicted election outcomes (Figure 4).
The Perils of Partisan Timing
Indeed, attempts to time the market based on political winds have proven treacherous. A hypothetical investor who only held equities during administrations of their preferred party, switching to cash otherwise, would have dramatically underperformed a simple buy-and-hold strategy over the long term. This performance gap underscores the dangers of letting political biases dictate investment decisions (Figure 5).
A similar conclusion comes from a National Bureau of Economic Research study on investor behavior following the 2016 US presidential election.2 The research reveals that investors in Republican-leaning areas increased their equity exposure after the election, while those in Democratic-leaning areas reduced theirs. This divergence, persisting for months, highlights how political beliefs can cloud financial judgment and lead to potentially suboptimal investment decisions.
Perhaps most concerning is the finding that some investors made drastic changes to their portfolios, with a small but significant group altering their equity exposure by 50% or more. Such large swings, likely driven more by political sentiment than by sound financial analysis, underscore the risks of allowing partisan views to dictate investment strategy. As markets generally rose in the months following the election, those who reduced their equity exposure based on political disappointment may have missed out on substantial gains.
Sector Surprises: When Conventional Wisdom Fails
Even those who correctly predict election results can find their company- or sector-specific bets going awry.3 Consider three recent examples that defied conventional wisdom:
1. Apple under Trump: Despite escalating US-China trade tensions during the Trump administration, shares of heavily China-exposed Apple gained 351%, handily outpacing the S&P’s 81% gain over the same period (Figure 6).
2. Clean energy under Trump: Despite Trump being viewed as no friend to the clean energy industry, the iShares Clean Energy ETF soared by 309% during the Trump administration, outpacing the S&P 500 while the traditional S&P 500 Energy sector lost 30%.
3. Energy under Biden: Contrary to fears of an anti-fossil fuel agenda, the S&P 500 Energy Sector Index has surged 148% under President Biden, outpacing the tech sector and more than doubling the broader market’s 53% return (Figure 7). Ironically, the iShares Clean Energy ETF lost half of its value while oil and gas production rose to record highs.
These cases illustrate the perils of making sweeping and “obvious” thematic bets based on perceived political headwinds or tailwinds.
Maintaining Perspective: Your Portfolio’s North Star
As election rhetoric intensifies and market volatility rises, investors would be wise to anchor themselves to time-tested principles rather than political projections. The data consistently shows that maintaining a well-diversified portfolio aligned with your long-term goals and risk tolerance is a far more reliable strategy than attempting to outsmart the market based on electoral outcomes.
While it’s natural — and even civically important — to have strong political convictions, the voting booth and investment account serve different purposes. By keeping your investment strategy above the political fray, you position yourself to navigate market cycles and capitalize on long-term growth, regardless of which party claims victory in November.
In the grand sweep of market history, presidential terms are mere chapters in a much longer story of economic progress and innovation. Successful investors are those who remain focused on this broader narrative, resisting the temptation to rewrite their financial plans with every electoral plot twist.
