EWU gamma exposure and option levels

United Kingdom · close 47.71 (+0.86% on the day, −0.24% over 5 sessions)

Dealers were net long gamma (for 9 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 49, 2.7% above the close, unchanged for 10 sessions. The put wall stands at 40, 16.2% below the close, unchanged for 10 sessions — too far away to have much pull day to day. Max pain for the front expiry is 47 (1.5% below the close). Implied volatility over 30 days is 20.7%, an IV rank of 56 on a scale where 0 is the lowest day of its own year and 100 the highest; realised volatility over 20 days is 11.7%. The options price a move of about ±5.9% over the next 30 days.

EWU 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 EWU 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 EWU goes, and not advice. See the terms.
