Collar¶
Long stock + Long put (lower strike) + Short call (higher strike)
Cost = Put premium - Call premium (often zero cost)
Protection = Between put and call strikes
where:
Put premiumcost of the downside put ·Call premiumcredit from the short upside call does: finances downside protection by selling away upside above the call strike — used by long-only managers to neutralize crash risk at near-zero cash cost, accepting capped upside; particularly common into year-end performance windows.

Practical Guidelines¶
- Define the Risk — What exactly are you hedging?
- Cost-Benefit — Hedge cost should be less than expected loss
- Basis Risk — Hedge instrument may not perfectly track exposure
- Rebalance — Hedges decay; rebalance regularly
- Don't Over-Hedge — Eliminating all risk eliminates all return
- Know When to Remove — Hedges aren't permanent
- Test Scenarios — Stress test your hedge before implementation
