Let's differentiate between Gamma and Vega.
Rant.
Both are 'Vol' - volatility ie every Option has Gamma and Vega, but when I see people say buy/sell Vol, they are not the same in terms of their reaction to market moves.
Mathematically derived and attached, they are acting detached at the moment due to large flows.
Gamma dominance (say <4week options) fast money.
Vega dominance (say >3months in Crypto) is longer-term assessment of future moves.
Vega has been crushed lately.
Gamma has been cheap af the last couple days.
My TG DMs etc 'Are we buying vol now?'
If you say you are 'buying' or 'selling vol', at the moment, we are not the same.
