$NCLH
This is what these corrupt MM‘s are doing

Market makers are supposed to be "neutral." If they sell you a
$20 call, they are "short" that volatility. As the price of NCLH creeps toward
$20, the MM is forced to buy shares to hedge.
The Corruption: To avoid the "squeeze" of having to buy more shares as the price rises, they will aggressively dump their existing inventory onto the "bid" in the final hours of trading. They are essentially selling into their own customers to make sure those
$20 calls stay "Out of the Money."
2. "Short Exempt" Abuse
You’ll often see a high volume of Short Exempt trades on days like this. These are trades that bypass the "Uptick Rule."
Market makers use this "exemption" under the guise of "maintaining liquidity," but in reality, they use it to hammer the price down even when there are no shares left to borrow. It’s essentially legalized naked shorting used to kill momentum.
