Technically we're still below the top he called (most recently). He could still be right (this time, for a few days to a few weeks to a few years).
Still technically true. Maybe for a few more minutes.
As far as short positions, I've never understood why an investment with a 100% max possible return ceiling and an infinite downside is a good idea. But more power to y'all.
While you are technically correct that a short seller can only make 100% while facing potential unlimited downside, sometimes the short run odds favour reducing your exposure while the market receeds from its overextended position. The market isn't going to drop to zero or double in that timeframe.
Yes it is market timing, and market timing isn't for most people on here, but it is for some of us, so why scoff? Passive investors need some degree of active investing to make the market and should be grateful to them for doing so by doing strategy also making passive investing possible.
