Stocks Go Down by 50 %, What Would Happen?

We've always got to be prepared for a stocks to go down by 50 %, at least a maybe even more than that. I never rely on a stock market money for the next five or ten years. And so i'm always thinking that way, and i'm always prepared for the downside. But what that said, let's talk about some possible upside here. So last week we talked about process. And of course, proces owns ten cent. And then naspers originally owned ten cents but then they spun it out to proces, and they own a chunk of proces. And then same with naspers? What's the discount? A for naspers?
