You still didn’t answer my main point which is what is stopping MMs from hedging those calls?? Average daily volume is 30M shares. You have no proof that it would be difficult for them to hedge if they had to.

They can hedge, (and probably are, now). When they hedge though, 1) They will drive up the price. Most of any given ADV is going to be algo-traded back and forth shares, so they will drive up the price more than you expect from the volumes 2) Those shares will get taken off the market, can't be lent out to shorts, can't be lent out to other market makers. This will constrain buy-side liquidity 3) The rising price will force a higher hedging requirement from shorts unrelated to Gills, and a higher hedging requirement to those who wrote the calls. 4) They will then go back to 1) and do it again. It looks like someone tried to do the hedge you describe on 2mm shares on Monday Jun 3, that's when the price went from $22 to $40. Price went down to 26 over the the next couple of days, and Gills posted his holdings. We're up to low $30s today. TLDR: Someone seems to have tried that, and found out there's a lot less liquidity than they wanted.

  Thanks for explaining it, tbh I hadn’t been paying attention and also don’t know where to find or how to interpret the data you’re talking about. That being said, one key assumption you’re making is that there are no motivated sellers. I don’t have the numbers in front of me but institutions own a lot of GME shares, and likely lent their shares to short sellers. As soon as they sell that significantly improves the situation for the call sellers.

    Oh for sure, price rises mean more selling. One sort of unique thing about GME is that a very unusual percentage of holdings seem to be held by ... r/wsb and r/superstonk retail holders, and they have talked themselves into never selling. There are literally videos of Frodo watching a giant green candlestick trade rising out of mordor over there today. So, the social engineering part is a big deal, too. It's not like someone at Susquehanna is like "cool, made my bag, how do we unwind?" In fact, Susquehanna is short here.

      That is a good point, but at the same time short % of float is much lower than it was in January 2021, so that’s a headwind that didn’t exist (even though it now has the superstonk tailwind) Anyways I hope you made some money on the move today. How are you accessing L2 data and how did you know how to infer that the calls weren’t hedged and that the call seller was having a hard time hedging?

        Agreed on short interest differences! I did make a little, but just play money. Most serious brokers offer level 2 data on subscription, eg interactive brokers. I’m not a public markets guy so I’ll leave off on trading qs for now, enjoy the ride though.
