Long straddle

"Something big is coming, I just don't know which way"

Election results. A court verdict. A company's results with a lot riding on them. Sometimes you're confident the market will move a lot but have no idea of direction. The long straddle is built for that.

Whichever way NIFTY goes, one leg dies and the other gains. You profit once the winning leg is worth more than the combined premium.

How big a move do you need?

The breakevens are 456.65 points away — about ±2% in two weeks. Is that a lot? Use the bell-curve trick from Module 2: with IV at 13%, one standard deviation for 14 days is 22,400 × 0.13 × √(14/365) ≈ 570 points.

So you need a move of roughly 0.8σ just to break even. It happens — but the straddle price already reflects the market's own estimate of the move. You only win if the move is bigger than the market expects.

The three enemies of a straddle buyer

1. 1

   Theta

   You own two options, so you pay double time decay. Every quiet day costs real money.

2. 2

   IV crush

   Before a big event IV is high, so the straddle is expensive. After the event IV collapses — both legs lose value at once, even if the market moves.

3. 3

   A move that is "big but not big enough"

   A 300-point move feels huge on the day, but still leaves this straddle in the red.
