Four Numbers That Explain the Move

Delta, gamma, theta and vega each measure sensitivity to one thing, and together they explain why a correct call still lost money.

This lesson is part of a Stock Alerts + Tools plan.

What the lesson covers

  1. 0:00Your call went up in price and lost money. The Greeks explain why.
  2. 0:05What each measures. Each one answers how much the option moves when one specific thing changes.
  3. 0:15Delta, two ways to read it. It is the move per dollar, and roughly the market's odds of finishing in the money.
  4. 0:24The one that catches people. Vega. Volatility collapsing after earnings can sink an option even on a correct call.
  5. 0:33How they interact. Gamma is largest near the strike and near expiry, which is where things move fast.
  6. 0:41Check all four before blaming direction.
