EWZ gamma exposure and option levels

Brazil · close 32.46 (−2.07% on the day, −23.77% over 5 sessions)

Dealers were net short gamma (for 5 sessions): when the price moves, their hedging goes with it, which can let the move stretch. The call wall — the strike with the most call open interest in reach — stands at 40, 23.2% above the close, unchanged for 2 sessions — too far away to have much pull day to day. The put wall stands at 30, 7.6% below the close, unchanged for 3 sessions. Further out, 50 above holds more open interest than any strike near the price — long-dated positions and hedges, too far away to act as a level. Max pain for the front expiry is 37 (14.0% above the close). Implied volatility over 30 days is 33.5%, an IV rank of 26 on a scale where 0 is the lowest day of its own year and 100 the highest; realised volatility over 20 days is 93.0%. The options price a move of about ±9.6% over the next 30 days.

EWZ and its option levels over the last year

The close, with the call wall and the put wall (the strikes the option book is heaviest at) and the gamma flip (the price where dealers’ net gamma changes sign). Each line is that day’s reading, not a level looked back on.

Implied against realised volatility

What the options charge for the next 30 days, against how much EWZ actually moved over the last 20. A gap between the two is the market’s price for uncertainty.

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.

IV rank and the priced move

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 next 30 days, as a percentage of the price.

Every figure is end-of-day and describes how the option market is positioned. It is not a forecast of where EWZ goes, and not advice. See the terms.
