protective-collar

A protective collar combines three positions: holding stock, buying a protective put to limit losses, and selling a covered call to offset the put cost. This strategy caps downside at the put strike while capping upside at the call strike, typically offsetting costs to near-zero or net credit over 30–90 day horizons.

A protective collar adds a short call to the put, generating premium that offsets or eliminates the put's cost. A put alone provides downside protection but no income offset. The collar trades unlimited upside for cost efficiency, making it ideal when you want defined risk without paying full put premiums.

Yes. This Skill uses numpy, pandas, and matplotlib to compute option Greeks, strike selections, P&L across price scenarios, and portfolio-level collar configurations. You'll need numpy≥1.24.0, pandas≥2.0.0, and matplotlib≥3.7.0 to run the analysis.

Use a collar when you own mid-to-large-cap stock, expect volatility within 30–90 days, and want to limit downside while offsetting hedging costs through call premium. It's cost-efficient for positions where you accept a defined cap on gains to reduce or eliminate protection expense.

Strike selection depends on your risk tolerance, cost constraints, and return targets. This Skill automates strike recommendations by computing P&L, Greeks, and payoff diagrams across strike pairs, helping you balance protection level, income generation, and upside cap for your portfolio context.

Collars cap your upside at the call strike, lock in opportunity cost if the stock rallies sharply, and require active management across positions with aligned expiries. Early assignment on short calls or shifts in implied volatility can affect economics before expiration.
