My friends who don't fully get my stock-buying habits often ask "if you could own one stock for the rest of your life," or "if you had just one stock to own while you were stranded on a desert island for years," what that stock might be.
They expect me to name some tech giant trading at multiples so high I'd need a NASA spacesuit to own it, or some biotech "just about" to "change the world," despite the very long odds on blind biotech bets.
Or a driverless car company… or a drone manufacturer… or some other firm making a device that everyone expects to be ubiquitous in a few years…
All super-sexy, exciting businesses, absolutely; fun to read about and speculate on, but not my cup of tea. And they're certainly not "the one stock."
Why? Because I have no idea which tech company will own 90% of the planet in 50 years, or which will be replaced in five years by a couple of dudes in Toledo building a gaming system in their garage.
When and if they reveal themselves, and they're selling cheap, maybe I'll buy 'em – maybe.
