What should investors expect in the stock market in light of the 2024 solar eclipse?

Investors clearly can get stars in their eyes when it comes to dreaming that they've found the next hot stock pick, super-charged cryptocurrency or, yes, even a rare Pokémon card to buy them that Bugatti.

But what happens with an eclipse?

For fun, and believe me it's clearly for fun, I asked a longtime source on Wall Street what kind of returns the Dow Jones Industrial Average saw in years when there was a total solar eclipse in the continental United States.

The much-anticipated eclipse April 8 will cross a swath of the United States, including a small sliver of southeast Michigan. The total phase of the solar eclipse will not be visible in New York City, home of Wall Street, but a partial solar eclipse is expected. The I LOVE NY tourism arm is promoting "Come for the Eclipse, Stay for New York."

Sam Stovall, chief investment strategist for CFRA Research, frequently compiles historical lists of stock performance during presidential terms or election years. He naturally was the first person I contacted to navigate the numbers when I thought about what happens when you mix stocks and eclipses.

The good news — if you're lifting your eyes to the heavens and wearing the appropriate ISO 12312-2 international standard solar eclipse eyewear — is that the Dow has tended to do pretty well in total eclipse years in the continental United States.

The Dow posted a positive year in 10 out of 13 total solar eclipse years on the list from 1900 through 2017.

The most breathtaking year for gains in that group was 1954 when the Dow rose 44%. Three other years had gains of 25% or higher: Up 30% in 1925, up 26.6% in 1945, and up 25.1% in 2017.

Oh, a few years were losers, including some meltdowns — 1923, 1930 and 1932.

The worst year was 1930 when the Dow darkened the economic landscape early in the Great Depression by tumbling 33.8%. The Dow was down 23.1% in 1932, also during the Great Depression, and fell 3.3% in 1923.

Other years were so-so, like 1970. Millions watched the eclipse in clear skies in 1970, called the "Eclipse of the Century" by NASA, with an "eerie twilight" being cast among the skyscrapers, according to the New York Times.

In 1970, the Dow was up 4.8% and then up 4.2% in 1979. Back in February 1979, the eclipse was visible from only the Pacific Northwest and the Dow was up 4.2%.

Wall Street has had quite a show already

The Dow, of course, has been offering its own spectacular show for much of 2024.

We've edged super close to 40,000 on the Dow. The blue chip index traded as high as 39,889.05 points on March 21. It closed at a record of 39,807.37 points on March 28. The Dow was up 5.6% through March 28.
