I went through the S-1 again, a lot of times insiders are strictly prohibited from any kind of hedging via derivatives. As best as I can tell however, that was not the case here. So yes, it might be a fiduciary hedging a large position.No idea why someone structures the way they do. It was a bullish trade for one side. Probably a fiduciary hedging into locked insider position.
When someone does a large transaction like that, is that negotiated prior to the print? IE is there person to person interaction between the buyer/seller or can something like that just hit wires? 4200 contracts on the Q's or a fang stock is no big deal, but something like this? It seems like that would have to be negotiated.
