ISRG options: max pain, gamma exposure and walls

Intuitive Surgical · close 443.59 (+0.83% on the day, −2.02% over 5 sessions)

Dealers were net long gamma (for 42 sessions): when the price moves, their hedging leans against it, which tends to calm it. The call wall — the strike with the most call open interest in reach — stands at 530, 19.5% above the close, unchanged for 16 sessions — too far away to have much pull day to day. The put wall stands at 350, 21.1% below the close, unchanged for 6 sessions — too far away to have much pull day to day. Max pain for the front expiry is 410 (7.6% below the close). Implied volatility over 30 days is 31.7%, an IV rank of 30 on a scale where 0 is the lowest day of its own year and 100 the highest; realised volatility over 20 days is 45.9%. The options price a move of about ±9.1% over the next 30 days.

How to read these figures

Gamma exposure (GEX)

How much dealers must buy or sell to stay hedged for each 1% move in the price. Long gamma means they trade against moves and dampen them; short gamma means they trade with moves and can amplify them. It is estimated from open interest and an assumption about which side dealers are on.

Call wall and put wall

The strikes where call and put open interest is heaviest within reach of the price. Prices often slow, or get pinned, near them into expiry; they are where a lot of hedging sits, not a guarantee.

Gamma flip

The price at which net dealer gamma changes sign. The same book acts as a brake above it and as an accelerator below it.

Max pain, IV rank and the priced move

Max pain is the strike where an expiry’s options are worth the least in total. IV rank places today’s implied volatility between the lowest (0) and the highest (100) of the last year. The priced move is what the options charge for the period, as a share of the price.
