Option Pricing and Volatility

    Why does the same exact option cost $3.00 one day and $12.00 the next — even when the stock barely moved? The answer is Implied Volatility… and IV Crush.

    Implied Volatility (IV) = The Market's Fear & Greed Meter

    Implied Volatility is NOT how much the stock moved yesterday.
    It is how much the market expects the stock to move in the future — expressed as a percentage.

    15–25 %

    Low IV – "Chill market"

    SPY on a boring Tuesday

    40–70 %

    High IV – "Nervous market"

    Before earnings or Fed meeting

    100 %+

    Extreme IV – "Panic mode"

    March 2020 crash, meme squeezes

    High IV = Expensive options
    Low IV = Cheap options
    (Everything else being equal — same strike, same expiration)

    IV Crush = The Overnight 50–90 % Wipeout

    IV Crush is what happens when the "event" everyone was scared of finally arrives… and the uncertainty disappears.

    Classic Example: Earnings

    • Monday: NVDA reports earnings Thursday → IV = 110 %
    • Options are crazy expensive (people betting on a huge move)
    • Thursday after close: NVDA beats, stock moves 9 %
    • Friday morning: IV collapses to 35 % → options lose 60–90 % overnight

    You can be 100 % right on direction and still lose money because of IV crush.

    Real price change example (NVDA $900 strike)

    Wednesday (pre-earnings):$48.00
    Friday (post-earnings):$8.00
    −83 % in 24 hours

    IV Cheat Sheet for Beginners

    When IV is LOW → Great time to BUY options

    Options are cheap, potential IV expansion = free upside

    When IV is HIGH → Great time to SELL options

    You collect massive premium, then pray for IV crush

    Rule #1 for new traders

    Never buy options the day before earnings
    (unless you love donating money)
