GLW

The price and the session change are a point-in-time snapshot taken at the time shown. The gamma levels run on a different clock: they are computed 2026-10-20 02:36 ET from the open interest carried on the option chain at that time and are not intraday values. Dealer positioning is an assumption, not an observable: open interest shows that a contract exists, never which side a dealer holds. How dealer gamma is computed.

GLW DEALER GAMMA BY STRIKE

Part of the SquawkFlow GEX Calculator: gamma by strike for any US stock. Compare with SPX GEX.

Net gamma exposure at each strike near GLW's spot price, signed from the dealer perspective, calls positive, puts negative. Green strikes are where hedging tends to dampen moves; red is where it tends to amplify them. Dealer positioning is an assumption rather than an observable, so treat these as a map of where hedging pressure concentrates, not a forecast.

Unit: USD of dealer gamma per 1 percent move in spot. A window of the GLW option chain, not the whole book: the 30 strikes nearest spot out of 68 seen, 264 contract rows spanning 2 expirations. Gamma is taken as the chain publishes it per contract; nothing here is re-priced. Crossed with the open interest carried on that chain.

New to these levels? Start with the call wall and put wall, or the zero gamma level where the sign of dealer hedging flips.

All captured expirations. Chain as of 2026-10-19 19:59:59 UTC.
