RE:RE:RE:ShortsRixpix, this short into a PP leaving residual warrants is indeed a common trade. However, one needs to secure a good borrow so you can hold the short AND finance the short over the 4month hold period. Some of the shares have tough borrow and/or super expensive borrow rates - like 50% annualized etc. Its not a free arbitrage....
Yo can also short the shares and trade the ranges - based on how many warrants you have and their strike price.
Sernova in my opinion was a very good deal, stock was strong out of the gates and you got a FULL warrant, very rare these days .
