Geez, imagine if you had also bought a put at the same strike and expiry date. You'd be in super dough now, with the price down to 130ish?
He would've gotten raped if the stock had rallied. He would be down 60 handles per put if the shares had rallied an equal figure. The deltas add to 100 (delimited). You're short a 10-delta call and you buy the same-strike put. The put is 90-delta which is dictated by parity/conversion arbitrage.
Mmm. By the way, all these options we've been talking about on stocks like GME...Are they American-style, Euro-style, or can you choose between the two types? It seems logical to me that an option that cannot be exercised against you until expiry is a good thing?
SN are american. Index are euro. It really doesn't matter as the guy isn't short any ITM and the last thing he would need to worry about is getting assigned on a 300 vol-figure.
Mormons bought GME and TSLA. https://markets.businessinsider.com...k50xpdc5oiykjouuvoksltqdcsdyzsothze2jj61j-g1k
Damn, they snapped up GSE for less than $19 a share! Freaking geniouses!!! BTW, I think somewhere you asked TPT about margin rates to short GME stock. Like 1.3% or less generally at IB (they move around a bit during the day).
