So, how's a poor investor supposed to predict what will happen in 50 years? Well, luckily, nobody's going to lock you into a single stock for that long. But if I had to choose one stock to buy and not touch for five decades, I'd go with a reliable choice: Berkshire Hathaway.
Master investor Warren Buffett's conglomerate has three big advantages for long-term investors. First, it's a very large company, and large companies tend to offer more stability than their smaller cousins. Second, it's incredibly diversified, with holdings in insurance, oil and gas, railroads, and even candy, among many others. That diversity should also help protect investors' money, even if one of those sectors experiences a prolonged slump or collapses entirely. And third, the company spits out boatloads of cash. Specifically, Berkshire today has $112 billion of cash on its books, comprising about one-third of its overall book value.
