This page displays the full GLW options chain for contracts expiring on 2026-08-21. Both call and put tables include contract symbols, last trade price, bid/ask quotes, daily change and percentage change, trading volume, open interest, implied volatility, and an in-the-money (ITM) flag. It is designed to give you a complete snapshot of how the market is pricing risk and direction for this specific expiry.
Around earnings, macro data releases, or company-specific news, traders often focus on a single expiration such as 2026-08-21. By monitoring changes in implied volatility, volume, and open interest for each strike, you can see where traders are concentrating their bets and hedges. Large shifts in activity on out-of-the-money calls or puts can be early signs of expected volatility or directional moves in GLW.
The ITM column highlights whether a contract is currently in-the-money for GLW: call options are ITM when their strike is below the current stock price, while put options are ITM when their strike is above the current stock price. ITM contracts have intrinsic value, while out-of-the-money options are purely time and volatility value. This distinction helps you quickly identify which strikes are already “in the money” for this expiry.
Implied volatility reflects how much movement the market expects for GLW between now and 2026-08-21. Higher IV typically means options are more expensive and the market is pricing in larger potential moves. You can compare IV across strikes and between calls and puts to identify skew – for example, expensive downside puts may indicate demand for crash protection, while rich upside calls can signal speculative interest.
No. This 2026-08-21 options chain gives a granular view for one maturity only. For a complete picture of positioning in GLW, you should also review the multi-expiry options overview where you can compare put/call ratios, total open interest and volume across different expiration dates. Combining both perspectives helps you understand whether traders are focused on very short-term moves or longer-dated themes.
The GLW options data on this page is refreshed regularly during market hours to reflect the latest trades, mid-market quotes, and open interest updates. Intraday changes in volume, open interest, and implied volatility can provide important signals about how sentiment and risk pricing are evolving as 2026-08-21 approaches.
