The Bear Put Spread

Delta measures how much your spread gains for every $1.00 the SPY falls. In a debit spread, we want a Negative Net Delta.

  • The Long Leg ($672): Delta -0.480 (You gain $0.48 for every $1 drop).

  • The Short Leg ($668): Delta -0.438 (You lose $0.43 for every $1 drop).

  • The Result: -0.480 – (-0.438) = -0.042.

The Bottom Line: Your “Net Delta” is -0.042. This means the spread value increases by approximately $4.20 per contract for every $1.00 SPY drops. While that sounds small, remember you only paid $152 for the trade, so every $4 move is a huge percentage of your cost!
