Schlumberger Stock Was Once as Hot as Nvidia. Why It’s a Buy.

Schlumberger was the Nvidia of the 1980s—and the beaten-down stock could still produce some Nvidia-like gains. It’s hard to remember now, but Schlumberger, now called SLB was one of the market’s hottest stocks as the leading servicer to the then-dominant energy industry, and at one point had the world’s fifth-largest market cap. SLB is still the world’s leading oil-services company, with operations in 100 countries, but energy matters little in the index, and the out-of-favor stock isn’t trading much higher than it did 40 years ago.
