Trade July 16th
Position: Short put on (GLW)
Overview You sold a cash-secured put on Corning Incorporated (GLW) and collected a premium of $1,221. This trade creates an obligation to buy 100 shares per contract at the option’s strike price if the option is assigned before or at expiration. The premium received reduces your effective purchase price or increases your return if the option expires worthless.
Key trade economics
Premium received: $1,221 (cash received up front)
Contracts: implied 1 contract for standard options (100 shares) if premium equals $1,221 net; adjust proportionally if multiple contracts
Break-even at expiration: strike price − (premium per share). Premium per share = $1,221 / 100 = $12.21. Example: if strike = $35, break-even = $35 − $12.21 = $22.79.
Maximum profit: limited to the premium received ($1,221). That occurs if GLW stays above the strike through expiration and the option expires worthless.
Maximum loss: substantial if assigned and the share price falls to zero: (strike − 0) × 100 − premium received. In practice, maximum loss = (strike × 100) − $1,221.
Breakeven timeline: realized only at expiration; early assignment can result in owning shares prior to expiration.
Risk and reward profile
Reward is limited and fixed (the $1,221 premium).
Downside risk is large and grows as the stock declines below the strike, reduced only by the premium received.
Probability of assignment depends on moneyness and time to expiration. If GLW stays above the strike, you keep the premium and incur no share purchase.
If assigned, you will purchase 100 shares at the strike price. Your effective cost basis will be strike − $12.21 per share.
Why investors sell puts on GLW
Income generation: traders seeking yield may sell puts to collect premium.
Desire to acquire stock: selling a put can be a way to buy GLW at a lower effective price (strike minus premium) compared with current market price.
Neutral-to-bullish view: sellers profit if GLW remains flat or rises.
Considerations and management actions
Cash-secured: ensure you have enough cash to buy 100 shares at the strike (strike × 100) if you intend to be assigned.
Rolling: if GLW moves against you, you can roll the put (buy back the short put and sell another further-out or lower-strike put) to defer assignment and collect/adjust premium, at the cost of additional transaction risk.
Closing early: buy back the put to lock in profit or limit loss before expiration.
Assignment: if assigned, evaluate whether to hold the shares, sell covered calls, or sell the shares (realizing the position and netting the premium into the purchase outcome).
Greeks and volatility: higher implied volatility inflates premium. A decline in IV reduces the short put’s mark-to-market liability, benefiting the seller; a rise in IV increases it.
Tax and capital considerations
Premium received is typically recognized when the option is closed, expires, or is assigned. Tax treatment can vary by jurisdiction and depends on whether you are assigned and how long you hold the resulting shares.
Practical next steps
Confirm exact strike and expiration for precise break-even and risk calculations.
Ensure cash is available for assignment if you want a cash-secured strategy.
Decide an exit/management plan: let expire, close early, roll, or accept assignment and manage the long position.
Summary You collected $1,221 selling a GLW put. That premium is your maximum profit if the option expires worthless. Your breakeven is the strike minus $12.21 per share. The trade converts to a purchase obligation for 100 shares at the strike if assigned, so be prepared with cash or a plan to manage assignment and downside risk.
