Current GLW snapshot
As of June 30, 2026, spot at $255.26, ATM IV 97.57%, IV rank 100.00%, expected move 27.97%. The bear put spread on GLW below is built from the same end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 31-day expiry.
Why this bear put spread structure on GLW specifically: GLW IV at 97.57% is rich versus its 1-year range, which makes a premium-buying GLW bear put spread relatively expensive in absolute-cost terms, with a market-implied 1-standard-deviation move of approximately 27.97% (roughly $71.41 on the underlying). The 31-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated GLW expiries trade a higher absolute premium for lower per-day decay. Position sizing on GLW should anchor to the underlying notional of $255.26 per share and to the trader's directional view on GLW stock.
GLW bear put spread setup
The GLW bear put spread below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With GLW near $255.26, the first option leg uses a $255.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed GLW chain at a 31-day expiry; the cross-strike IV skew is reflected directly in the per-leg values rather than approximated. Quantity sizing assumes one contract per option leg (or 100 GLW shares for the stock leg in covered calls and collars).

|---|---|---|---|
| Buy 1 | Put | $255.00 | $28.88 |
| Sell 1 | Put | $240.00 | $20.88 |

GLW thesis for this bear put spread
The market-implied 1-standard-deviation range for GLW extends from approximately $183.85 on the downside to $326.67 on the upside. A GLW bear put spread caps both the risk and the reward of a bearish position; relative to an outright long put on GLW, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current GLW IV rank near 100.00% sits in the upper third of its 1-year distribution, which historically reverts; this raises the bar for premium-buying structures and lowers it for premium-selling structures on GLW at 97.57%. As a Technology name, GLW options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to GLW-specific events.
GLW bear put spread positions are structurally moderately bearish; the modeled P&L assumes European-style exercise at expiration and ignores early assignment, transaction costs, dividends paid before expiry on the stock leg (when present), and the bid-ask spread on the listed chain. GLW positions also carry Technology sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move GLW alongside the broader basket even when GLW-specific fundamentals are unchanged. Long-premium structures like a bear put spread on GLW are particularly exposed to IV-crush risk through scheduled events (earnings, FDA decisions, central-bank meetings) where IV typically contracts post-event regardless of the directional outcome. Always rebuild the position from current GLW chain quotes before placing a trade.
