If I Could Only Buy and Hold a Single Stock, This Would Be It.
What if you could only own one stock forever? My pick for a single-stock portfolio might surprise you.

Let's make this clear from the start: I would never recommend owning just one stock for the long haul.
A proper nest egg needs some variety, either in a carefully assembled basket of diverse stocks or focused on a broad market-tracking exchange-traded fund (ETF). For the sake of argument, however, I could imagine buying some Berkshire Hathaway (NYSE: BRK.A) (NYSE: BRK.B) stock and just letting it roll.
I know, I know. You wanted me to double down on Amazon (NASDAQ: AMZN), whose stock has absolutely crushed the general market in the long run. Or I could have picked Netflix (NASDAQ: NFLX), the media-streaming pioneer that's created most of my wealth so far and that might join the trillion-dollar market cap club in a few years. Perhaps you expected Nvidia (NASDAQ: NVDA), with its unmatched five-year returns and huge long-term future in the artificial intelligence (AI) industry.
