Shorting before the merger wouldn’t have made any sense: the stock price went from around $17.50 to over $50 within the first week of trading and probably won’t come back to earth for a while. Meanwhile borrowing costs, after that initial spike when the stock was at its highest, were astronomical, so it wasn’t economical to do it right after, either.
The real 4D chess would be to get that lockup waived, short the stock now (borrowing costs have since fallen back to earth), sell your shares, then close out the short after the price drops (sure, you run the risk that the SEC goes after you for stock manipulation, but I doubt Trump cares).
Yeah but to make any real money on a short position taken prior to listing, the stock would have to drop well below that $17 price. Will that happen? Maybe. But I personally wouldn’t bank on it. My bet is that pre-listing price will be a bit of a floor since so many retail meme stock types got in on that price pre-merger and won’t want to get out.
