The S&P 500 (^GSPC 0.43%) is down more than 3% since the start of the year, and many top tech stocks that were hot buys in recent years have been struggling in the first few months of 2026. Investors appear to be growing concerned with the market, and the war in Iran may be providing them with even more of a reason to stay on the sidelines. While there is plenty of uncertainty in the markets, billionaire investor Warren Buffett has experienced it all and remained invested throughout. One fact that may surprise you is when Buffett bought his first stock. Image source: The Motley Fool. Buffett's first stock purchase was during World War II Buffett got started in investing early, at age 11.

Cities Service Preferred was the first stock he bought, and that was in 1942 -- in the midst of World War II. While it wouldn't end up being a long-term holding for Buffett, it is nonetheless symbolic of his temperament and focus on stocks rather than economic conditions, politics, or even war. Back then, there was great uncertainty as to how things would play out. World War II was still multiple years away from coming to an end. Buying a stock at the time may have been considered extremely risky. The war in Iran is a troubling conflict today, but it's not even close to being on the same scale as World War II.

That's where investing in exchange-traded funds (ETFs) can be a good move to consider. They can spread out your risk across not only a few stocks but dozens and even hundreds or thousands. Through S&P 500 index funds, you can also track the S&P 500, which gives you exposure to the top stocks on the U.S. markets, enabling you to diversify your position while benefiting from the market's long-term growth. Historically, the S&P 500 has averaged an annual return of 10% To grow your portfolio, however, the key thing is to remain invested and hold on for the long term. Trying to time the market and get in and out at the right times is incredibly difficult, and it can lead to subpar returns and cause you to miss out on gains along the way. Staying invested and tracking the S&P 500 through an index fund can be a relatively safe option to consider for the long haul.Read NextApr 7, 2026 •By David Jagielski, CPAThese Are the Four Most Dangerous Words in Investing, According to This Legendary InvestorApr 7, 2026 •By David DierkingStop Checking Your Portfolio Every Day: Here Is What It Is Actually Costing YouApr 7, 2026 •By Sean WilliamsAre Stagflation Fears Creeping Back Into the Picture?
