Bear rallies are fierce. I do not think we've hit bottom yet. Notably this opinion is shared by Michael Burry, Jeremy Grantham, and Ray Dalio, among others.
bear markets tend to be much briefer than bull markets. Odds are if you try to time it you will end up selling too soon, buying back too late. How do you know if a bear market rally is the start of a new bull market? You don't, which is why I err on the side of not selling.
While this is true, bear markets usually last 12-18 months. We're just getting started.
I think it's fine (but not optimal) not to sell if you're playing the long game.
I'm all in cash and short positions right now. If my investing track record is anything to go by, that's a signal we've hit bottom. I'm betting otherwise, but what do I know.
