If you don't know much about investing then you shouldn't short anything ever. People who know about investing will tell you that even when your logic is 100 percent sound, the market isn't that predictable and in general the market can stay irrational longer than you can stay solvent.
Plus, the news of this would already be priced into the stock, so if anything the price is already low and these companies would need to pivot their business (which would increase the value again) or die (which would lower the price marginally, to zero). Either way, shorting is a bad strategy in this case.
Theoretically, yes. A short is sorta a negative stock. When you hold a normal stock, the price can never go below zero. But when you hold a negative stock, there’s no maximum value that stock could rise to.
Infinite and astronomical are used interchangeably here. Since you have to return a share to the person you borrowed it from, if you borrowed 1000 shares at $5 and sold them to make 5k, if the price jumps to something like $350 like gamestop, it would cost you $350,000 to cover them.
Making 5k to lose 350k might as well be an infinite loss ot that investor, even though its technically a "smallish" sum. At that scale, it would destroy most people.
You can also pay to keep a short going generally and try to wait out the madness, but you have to stay solvent to do it. The very stupid and very surprising "diamond handing" apes caused some hedge fund issues, although I think most just shrugged into other financial instruments.
I feel like shorting will always be riskier than normal investing. With stocks you have people at the company doing their best to raise that stock. With Shorts you are betting against a company that's trying to survive.
The chances of the CEO pulling something out of their ass, dubious or not, to maintain their profits is too high.
If you get investing returns (like from shorting those companies)… you’re ironically not eligible to use the IRS direct file pilot (or at least for this year).
Edit: this isn’t to knock direct file… which is good and cool (and should be expanded to have more features)
Those companies actually helped develop this, see "free file alliance membership" for details. It includes 17 private companies such as Intuit, H&R Block, TaxSlayer, Tax$simple, etc.
For what it's worth... You're already eligible to a free tax return if you're under a certain income. Edit: Reference - I think a lot of people are unaware of this.
The companies also sold all that data from people for years. If you used ublock origin you could see all the scripts linking to data brokers infecting their web pages.
The easiest way to get rid of a headache is to make some toast, then spread peanut butter on one slice and mayonnaise on the other, smash them together and eat it and as you are chewing just slam your head into the toaster as hard as possible.
