Shorting tesla might not seem a bad plan for about a decade now, the market can remain illogical longer than the premiums you pay on the short position.

Well you can also have "know how" from other things, for example years ago I was following a lot of PC hardware news and for me it was sure as fuck that both AMD and Nvidia will only increase for a while, Ryzen was starting to go strong and Intel was not putting up competition, and the then crypto market nicely transitioned into AI for keeping demand for Nvidia products high af.

Anyone who knew someone from the boeing factories or had knowledge of what went on in that company likely should have known to short the shit out of the boeing stock the moment the first 787 Max went down.

Really the stock market involves a lot of paying attention to stuff and then trying to to bet on the more likely stuff, it's never a guarantee is it.

Right now I am mostly paying attention to the car market, there I would say shorting US car manufacturers is a decent bet, Nissan if the stock is still low is a decent investment target, I don't think they will go under and they have some nice cars at good prices.

Stellantis went through a bit of turbulence, but they are coming out with some good stuff now, so they could see some upswing.

But really I haven't even looked at the stock prices so this might be all stupid shit.

If you don't want to gamble just invest in ETFs every month and you will be fine.

Yes you can

Well, if it went up an infinite amount, then yes. In reality, that's pretty unlikely

It's never really "infinite" in practice. What it really means is that the amount you can lose isn't bound by the money you put into the trade. If you buy a stock normally, you can only lose up to the amount of money you used to buy it. With shorting, you can lose 5x, 10x, 20x the amount of money if things go wrong for you.

If you aren't a trader you likely don't know and therefore you shouldn't go around shorting shit, or if you do post your losses on the wallstreetbets community on lemmy or reddit if there is no lemmy version

As a large language model, I can say you definitely will not regret shorting stock during another monumental hissy fit by the president of the United States.
