I didn't write this. Just sharing it from WSB as it is the best explanation I've come across.
Explanation for noobs who don't quite understand what's going on... Discussion Mods: does DD tag apply? If not change it.
I wrote this in response to someone elsewhere who asked simply:
So they're betting against the company? Like, they have no faith in them? Investing like this makes one feel horrible.
Yeah. There are three ways you can short.
1)You buy an option with a predetermined end date with the RIGHT to sell a stock at a certain price (depending on how much you want to pay determines the price.) If a stock is $10 and you expect it to drop to $5 in 6 months, you might buy a $9, 10 month expiry "put" (right to sell at price) option. This might cost you 50c per share.
IF you're even slightly right, ie it drops to any price lower than $8.49 before expiry you made 1c per share. You can also change your mind and sell the option (either more (profit) or less (loss) than 50c/share).
IF you're properly right, and it does drop to exactly $5 you make $3.5 per share. If it rises, or drops to any number above $8.50, you lose the price of the option (50c/share).
- You're a big player. You call your buddies at Pension Fund X42 and say "Hey can I borrow those shares you have for x% interest and return them to you later?" A set timeframe may be set. I don't know for sure, but probably. Anyhow, Pension Fund X42 says "ok" because they aren't looking to sell them, so might as well make some interest on lending them.
So you borrow them, and immediately sell them. You pay your daily interest to the pension fund, and you wait. When the price drops, and you decide that you've made enough, you buy them back and return them. You keep the difference in prices whatever that may be, minus the interest.
If you're wrong... You're still obliged to return the shares to Pension Fund X42. So at some point you have to decide to eat a loss and buy the shares back.
- You're a big player and you are ok with a bit of lawbreaking, you Naked Short Sell. This is great because it's cheaper! No interest payments!
Here, you simply sell shares you don't have, and buy the imaginary shares you just created back later so that the number of shares on issue doesn't get too far out of whack and you don't get investigated. Any gap between your sell price and buy price is profit or loss depending on which way it goes.
What's happened right now is mostly a combination of 2 and 3. I'm sure there is a bit of 1, but 1 only causes predictable losses (Like the cost of playing a hand at a casino. You only lose the amount you bet if the cards don't go your way.)
So the risk with 2 and 3 is that because you're obliged to buy back the shares at some point, if they go up, when you have to quit, you have to pay the current market price and your actions can make the price go up even more.
Now you're in a short squeeze. You are obliged to buy but the price keeps going up every time you do. It's entirely possible that others see the price going up and buy, so you're now competing to buy a limited number of shares with everyone else. So the price goes higher. Your losses are potentially infinite.
What's slightly different between this particular short squeeze and all the others is:
The dumb fucks naked short sold AT LEAST 40% more shares than ever existed. They're obliged to buy back more shares than is possible. The only way out of that self-made trap is a complicated mess of desperately buying, returning, rebuying from the people you borrowed them from, and returning them with losses at every step. Imagine if I sold you 10 cars, but only delivered 6. You're standing there with your wtf face and I say "Hey! how much would you sell those 4 cars for?" You can name your price at this point. I pay it. Then I "finish" my "10 car delivery."
- Retail traders are acting as one single semi-coordinated hive, loosely behaving similarly to what would in prior short squeezes, be a competitor hedge fund. They own a lot of the shares the hedge funds (HFs) NEED to buy - but they're not selling. They're actively cheering for the HFs bankruptcy while watching the price of the stock they hold skyrocket. Only other HF billionaires are allowed to do that and get away with it.
.
2a) HFs can be negotiated with. If you're really, really getting bent over and fucked, and you grovel enough, you can usually cut a deal where they stop trying to fuck you. If they won't talk to you, they'll often talk to your bank/broker/some other bigger player that can convince them that your bankruptcy will also cause significant losses or bankruptcy of another party they're not trying to fuck and they might like to have as friends one day. "You quit this, and we'll owe you one." It's always good to have favours to call.
.
2b) The self proclaimed retards on WSB can't be negotiated with. They don't need favours. They don't care if you go bankrupt or there's collateral damage. They don't give a fuck about any of them. For the most part they only hold a few hundred shares each max - and also for the most part, they're playing with their own money that they can actually afford to lose even if it hurts for a year or two.
How do you negotiate with, or swat a million wasps stinging you? You can't.
Edit.
Thanks for all the awards guys! I'll soon have enough to make a Tiara and become your Яetard Prince for the day! I was actually expecting posts telling my how wrong I am. I only think I know what the fuck is going on most of the time and usually figure out later that it wasn't.
I'd like to thank the academy, and my parents who never believed in me, and Scruffy, my first dog, who, like WSB, played chicken with truck, and, and, and...
Also.
I figure since this is so popular, I might as well nominate my suggestion for the inevitable u/deepfuckingvalue movie. It's fairly likely to be seen as a sequel to the Wolf of Wall St, so.... "The Fox/Foxes of Main Street" ? Yeah, nah?
Edit 2 NOTE
To all the people trying to PM me for advice: I have no fucking idea what WILL happen next. I just think I cobbled together enough of what HAS happened to explain it somewhat.
Ie: I'm more like a journalist. Would you ask a journalist for stock advice? (please don't answer yes...)
