I am aware of a number of upper-income folks who justify their continuing support of Donald Trump by asserting that–“like most Republicans”– he has been better for their portfolios. That has always struck me as a poor excuse for ignoring what another Trump Presidency would do to the country (and for that matter, the world), but I’ve chalked it up to selfishness and (misunderstood/shortsighted) self-interest.
Evidently, I should have attributed it to ignorance, because it turns out that–when it comes to investment returns– Democratic administrations have greatly out-performed Republican ones.
As I was reading a recent issue of the Indianapolis Business Journal–a publication that covers local government far more thoroughly than the Indianapolis Star, by the way–I came across the regular column by Mickey Kim devoted to giving investment advice. This particular column was titled “Keep Calm and Don’t Mix Politics with your Portfolio,” and it was an effort to persuade people not to base their investment strategies on partisanship rather than performance, not to suggest that one party was better than the other for investment.
But the data was eye-opening, at least for me. (I readily admit to chosen ignorance about all things investment.)
My friend Sam Stovall, chief investment strategist for Wall Street research firm CFRA, dissected price changes for the S&P 500 going back to 1945 based on election results.
Republican administrations are generally viewed as “pro-business,” and conventional wisdom is that stocks do better with a Republican in the White House. There has, indeed, been a huge difference in returns during Democratic versus Republican administrations. However, as is often the case, conventional wisdom is wrong. Past performance is no guarantee of future results, but Stovall calculated from Harry Truman’s inauguration on April 12, 1945, through March 15, 2024, the average annual return for the S&P 500 was 44% higher with Democrats in the White House (9.5% vs. 6.6% during Republican administrations).
Further, according to Invesco and Haver Analytics, hypothetically speaking, the best-performing portfolio from 1900 to 2023 was the “bipartisan” one that stayed fully invested in the Dow Jones industrial average (a price-weighted index—cannot be invested in directly—of the 30 largest, most widely held stocks traded on the New York Stock Exchange) during both Democratic and Republican administrations. Again, past performance is no guarantee of future results, but starting with $10,000, this portfolio grew to almost $9.9 million.
Conversely, a “partisan” portfolio, invested only during Democratic or Republican administrations, underperformed by millions of dollars. The same $10,000 invested only during Democratic administrations grew to about $528,000. Invested only during Republican administrations, the initial $10,000 grew to a bit less than $181,000.
Kim concluded this analysis by reiterating his intended message, that “there can be a huge cost to letting a partisan political storm crash your portfolio.” His sound advice: “Develop an investment plan based on your long-term goals and stick to it. Your financial future will depend far more on how much you save and invest, not who wins the election.”
I am in no position to quibble with that advice, which strikes me as quite sound, but it certainly does raise a question about those upper-income Trump apologists. I suppose it’s possible that their portfolios grew under Trump, but given the truly excellent performance of the economy during the Biden Administration, it’s quite likely they’ve done as well or better with a Democrat in the White House. Is their purported reliance on portfolio performance an evasion intended to mask the actual reasons they support Trump (racism, misogyny, isolationism…)? Or do they actually not understand the significance of the data I’ve cited above?
Perhaps they’ve simply and unthinkingly accepted the old “country club Republican” belief that the GOP is the party looking out for the interests of the business community, while Democrats are “giving away” tax dollars via welfare and government spending. If so, someone needs to explain to them that both the short and long-term interests of the business community include such things as social stability, a well-maintained infrastructure, an educated and adequate workforce, and a population with enough disposable income to support robust consumer demand.
As investors are often admonished, past performance is no guarantee of future results. But the odds would certainly seem to be in the Democrats’ –and Biden’s–favor.
