Mark Cuban comments:
"“As long as we’re allowing companies to trade stocks in milliseconds, how can we expect this to be an investors market?” Cuban said. “Until you change that, you can’t change what’s happening with WallStreetBets.”
“When you short a stock, there’s a [vigorish] on it,” which is essentially a fee for placing a bet, Cuban said. “You have to borrow it and you’re paying some percentage to whoever owns a stock and is loaning it out. And as someone who has shorted stocks many times, you know when that vig is high, you know exactly what you’re getting into and you know exactly what the risks are and you just hope something like this doesn’t happen.”
He's kind of a tool, but he's a sharp tool. (I like the guy, and he's certainly right here).
