Regret to buy the call

$Micron Technology (MU.US)$ Yesterday, I checked its financial reporting in the past three quarters, and I was wondering whether the option price would jump when its stock price jump above 105 after its earnings report, even if the IV (Implied Volatility) crushed. I ever planned to bet a call (Ticker: MU 240927 100 C), but I thought I may not afford this cost.
