If it were possible to be certain about such things, the big moneyed interests would already be there and would've set traps to take your money when you try to follow them.

It's just gambling, comrade. Always remember this.

If I were gambling, I'd be betting on a recession starting in the next year. So I guess you could short some companies that you think would absolutely tank (you'd be gambling on that happening fairly soon) or withdraw your investmenta for a bit. Again, both are gambling.

Another thing you can do is ride pump & dump cycles for stupid hype shit and new cryptos and such. You will essentially be making money off of people just like yourself who don't bail early enough or joined too late - or sometimes from companies doing shady shit. It's difficult to know when to do either, so you'd need to embed yourself in these communities and make educated guesses.

Never, ever put more money into gambling than you can rationalize losing or watching go poof in a week and then needing to wait five years to maybe recover it. You'll also probably make more money by spending the time learning a skill and putting money into some kind of more stable investment like index funds or a solar panel farm or bonds.
