A pump and dump will always hurt short sellers on the way up, by definition, right? 
AFAIK there hasn’t been a short squeeze yet (short sellers are still able to borrow shares) and it’s unsure if it will happen (and GME can always sell more shares as well esp if they think they’re overvalued).
Edit: anyway sounds fun, just make sure you understand what you’re going into.
rest assured, i have zero idea what i am doing.
fully agree, but the magnitude in such a scenario is different if 20% of floating shares are shorted or 140%… and there were definitely (early) short sellers “squeezed” out of their position IMHO - but new ones are stepping in, keeping the short-ratio +/- the same…
edit: 
I wonder how many hedge funds are trading the momentum and printing money too
(in addition to the market makers taking their fees)
I wouldn’t be surprised if there’s a few funds who have automated momentum trading from wsb data
For sure they are - this thread was an interesting read
Its a fascinating case of game theory and market structure - who is going to blink first? Undoubtedly a lot of retail investors are going to get hurt, which is why its important they only participate in things like this with play money.
I’ve never done anything like this before - you can read my other thread where I simply buy and hold index funds - but the FOMO was real on this one and I succumbed haha.
afaik that thread if full of mistake: https://twitter.com/matt_levine/status/1354131557360021505
(this is Matt Levine’s area of expertise, while the original thread is from a tech person?)
… those are rookie numbers! 
edit: 
edit 2: WTF!? 380%
… and regarding AMC: The eow 9C option traded at 0.18 yesterday evening - now those are ~8$ deep ITM! That’s a 44-fold in a few hours 
Zero. But it’s lots of fun to watch.
It is kind of fun to watch: GME is bringing literally bringing part of the internet to its limits rn.
Is there actually a lot of money? I thought that was massively leveraged
Restrict retail access to leveraged trading?
It came to my mind too…as a final act before “everything grows” bubble bursts…
If an ETF can lend securities, they might lend them to Melvin, right? If then Melvin go bust, the ETF might have some issues as well.
But it’s only like 20B traded daily? Doesn’t seem like much (comparatively), and I don’t think there’s any systemic risk, what kind of thing do you envision?
I don’t usually follow my portfolio daily, so I could be wrong, but today seems a bit crazy in general. VT is down 2%. My worst performing stock is down 6%. My best performing stock is up 15% (and no, not related to the short squeeze craze, still not pulled the trigger to join the melee).
A possible systemic danger: If the shortsellers lose massively and have to liquidate other assets to cover those losses, they might liquidate otherwise solid stocks. If that happens on a large enough scale, with the market very jittery in general, this might be the spark to start a general sell-off.
Great - if what you say does happen - then I think people should adjust their asset allocation accordingly and keep some powder dry to buy the dips.
For those that missed out last March - there might be another opportunity to scale into the market at a lower valuation.
Thanks. Just saw, you had the same thoughts. It’s not that far fetched an idea then… Oh boy, just when I was getting accustomed to have nice monthly capital gains…
EDIT:
Yes. Now what to spend my dry powder on? GME this week? Or speculate for a dip and buy that later? This is not getting easier 
Imho the rocket has already launched for GME. I’m in the process of unwinding. I left a small position strapped to the rocket in case it goes to Mars on Friday. In other words: I’m playing with house money now and wouldn’t recommend anyone touching anything except the sell button. Let history prove me wrong.
I would welcome a general dip with open arms. I’m still bummed about sleeping in March and I have a lot of cash.
Meanwhile yahoo talk about a “Fed decision”.
I wonder if even this time the Fed will bail out whoever is in needs.
