Corning Incorporated closed at USD 194.80, down 1.01%. The day's options activity was highlighted by a significant bearish premium collection trade, with a large out-of-the-money call sale dominating the flow and signaling a capped outlook for the stock.

Options Indicators

GLW’s implied volatility is 94.84%, and with an IV percentile of 99.20%, current option volatility stands at an extremely elevated level relative to its own historical range. This suggests options are priced expensively, with the market assigning unusually high near-term uncertainty. At the same time, the IV/HV ratio of 0.74 indicates implied volatility is below historical realized volatility, implying that despite the very high absolute IV reading, current option premiums are not as stretched versus recent actual movement as the percentile alone might suggest. The Call/Put volume ratio is 1.98.

Large Trades

A CALL sale worth $0.47 million was the standout large trade, with 8,947 contracts sold at the 250.0 strike expiring on 2026-07-10. With GLW referenced at 194.8, this strike sits out of the money, making it a bearish or at least capped-upside position that reflects the view that shares are unlikely to rally through 250.0 by expiration. As a single-leg short call, the trade most likely represents premium collection or a directional stance that volatility and upside expectations are overstated at that strike.

Overall sentiment in GLW large trades was clearly bearish. With all of the meaningful large-trade activity concentrated in an out-of-the-money call sale, the flow suggests traders are leaning against a major upside move and are positioning either to harvest option premium or to express a restrained outlook on GLW over the stated expiry.

Strategy Reference

A seller preferring a very low assignment probability could look to sell a call at a strike like 300.0, while a trader seeking defined risk could implement a bear call spread, selling the 250.0 call and buying a higher strike call to cap margin requirements.
