I Don't Get What I Did Wrong on This SPY Call? on 4/12/2021, i bought 84 SPY210716C460 at $0.66 a piece and the price of the underlying that day was $411ish. today, SPY is at $417ish, but I'm down 30% ($0.47 a contract) - it seems like when SPY drops a few cents, the options contract dips hard, but when SPY's green, it doesn't seem to recover. it's still quite a bit of time until expiration, so i don't think theta is the issue here. what am i doing wrong?
