This Indestructible Buffett Stock Is Soaring, But Is It a Buy?

Warren Buffett has a knack for picking winners to invest in with his company Berkshire Hathaway (NYSE: BRK.A, BRK.B). With plenty of patience and the Oracle of Omaha's time-tested value investing strategy, he buys businesses that others would eschew and then waits for them to blossom into multi-baggers as years pass. Usually, Buffett stocks don't skyrocket in the course of a year -- but there's a recent exception to that rule which might be worth considering.
