Corning Incorporated closed at USD 159.89, gaining 9.04%.

Despite the sharp rally, institutional options flow painted a starkly different picture. A single massive put sweep dominated activity, with 2,500 contracts of the September 2026 $120 puts purchased for $0.83 million. This bearish bet, executed deep out-of-the-money, stands in stark contrast to the day’s bullish price action and signals a strong conviction that the stock faces significant downside risk over the coming year and a half.

Options Indicators

GLW’s implied volatility is 84.56%, and with an IV percentile of 89.64%, current option volatility sits in a clearly elevated regime. That means options are priced expensively relative to GLW’s own recent history, with the market embedding a high level of expected movement. The IV/HV ratio of 0.98 suggests implied volatility is broadly in line with realized volatility, so while option premiums are rich on a historical percentile basis, they are not dramatically stretched versus the stock’s actual recent movement. The Call/Put volume ratio is 1.76.

Large Trades

A PUT buy worth $0.83 million was the standout large trade, consisting of 2,500 contracts of the September 18, 2026 $120.00 put purchased outright. With GLW referenced at $159.89, this strike is currently out-of-the-money, meaning the buyer is positioning for a sizable downside move over a longer time horizon before the option expires. As a single-leg put purchase, the trade is a clearly bearish expression that uses limited premium outlay to gain leveraged downside exposure, while also potentially serving as portfolio protection against a material decline in the stock.

Overall, the large-trade flow in GLW was clearly bearish. The activity was entirely dominated by downside positioning, with no offsetting bullish large trades appearing in the aggregated data, which suggests institutional traders were focused on hedging downside risk or expressing a negative forward view on the shares. The use of a long-dated out-of-the-money put further points to expectations for a meaningful adverse move rather than a near-term tactical hedge alone, leaving the overall conclusion decisively bearish.

Strategy Reference

For premium sellers fading this extreme bearish sentiment, the elevated IV percentile offers an opportunity to sell a deep out-of-the-money put, such as the $120 strike, which currently sits far below the spot price and carries a low assignment probability, while the high premium cushion provides a buffer against adverse moves.
