Don’t Buy Any Stock in 2025 Unless It Passes This Test

Arguably the world’s greatest stock picker isn’t picking many stocks these days. Warren Buffett has been a net seller of stocks for eight consecutive quarters. I suspect when Berkshire Hathaway discloses the transactions it made in the fourth quarter of 2024, that count will increase to nine.

There’s a reason Buffett isn’t buying many stocks — and it’s the same reason he ranks among the greatest investors of all time. Buffett is a master stock picker because he’s highly selective about which stocks he buys.

Your chances of investing success will likely be greater if you’re as picky as Buffett. Don’t buy any stock in 2025 unless it passes this Buffett test.

Can we really know the “magic” process Buffett uses to select the stocks he buys? Actually, yes. In his 2013 letter to Berkshire Hathaway shareholders, the legendary investor revealed exactly what he does to select stocks. Buffet revealed a two-part test in that shareholder letter. By the way, it’s very similar to the process he uses to identify companies for Berkshire to acquire.

Buffett first determines whether he can “sensibly estimate an earnings range for five years out or more.” The operative word there is “sensibly.” He doesn’t pluck numbers out of the air but instead thoroughly reviews a company’s business along with industry trends to make the best earnings estimate possible.

Note that five years is a minimum estimation period. Buffett wants to avoid investing in a business that might temporarily deliver strong earnings growth only for that growth to quickly evaporate. In his letter to Berkshire shareholders, Buffett wrote that if he can’t estimate future earnings, he moves on to the next stock.

Buffett’s second step is to buy a stock only if it trades at “a reasonable price” relative to the lower end of his estimated earnings range. He will buy a stock only if it’s reasonably valued using this approach. Again, if the stock doesn’t pass this second step, he moves on.

This two-step test used by Buffett might seem simple. However, it’s more difficult to follow than you might think.

For one thing, “sensibly” estimating a company’s earnings over five years or more can be challenging. If you’ve ever wondered why Buffett didn’t invest in Apple or Amazon earlier than he did — or never bought stocks such as Nvidia that turned out to be massive winners — it’s because he couldn’t project their future earnings with enough confidence.
