Hedging is a risk management technique that involves taking an offsetting position to reduce or eliminate potential losses in your existing investments. Think of it as insurance for your portfolio—you pay a premium (the cost of the hedge) in exchange for protection against adverse price movements.
- Hedging protects against losses but also limits potential gains
- The cost of the hedge (premium, opportunity cost) is the price of protection
- Perfect hedges are rare—most hedges reduce risk rather than eliminate it
How Hedging Works
Hedging creates a counterbalancing position that profits when your main position loses, and vice versa. The goal is to reduce overall portfolio volatility and protect against worst-case scenarios.
Unhedged Portfolio:
- Long 100 shares at $100 = $10,000 exposure
- Stock drops to $80 = $2,000 loss
Hedged Portfolio:
- Long 100 shares at $100
- Long 1 Put Option (100 shares) at $95 strike, cost $200
- Stock drops to $80:
- Stock loss: $2,000
- Put gain: ($95-$80) × 100 = $1,500
- Net loss: $500 + $200 premium = $700
Quick Reference: Common Hedging Strategies
| Strategy | How It Works | Cost | Protection |
|---|---|---|---|
| Protective Put | Buy put options on stocks owned | Premium paid | Full downside protection |
| Collar | Buy put, sell call on same stock | Low/zero cost | Capped upside and downside |
| Inverse ETF | Buy ETF that moves opposite to market | Management fees | General market hedge |
| Futures Short | Sell futures against long position | Margin + carry | Direct price hedge |
| Pairs Trade | Long one stock, short correlated stock | Spread difference | Sector-neutral exposure |
Example: Protective Put Hedge
Position: 500 shares of AAPL at $175 = $87,500
Concern: Earnings announcement next week could cause 15% drop
Hedge: Buy 5 put contracts (500 shares) at $170 strike for $3.50/share = $1,750
Outcomes:
| AAPL Price | Stock Value | Put Value | Net Position | Result |
|---|---|---|---|---|
| $190 | $95,000 | $0 | $93,250 | +$5,750 (reduced by premium) |
| $175 | $87,500 | $0 | $85,750 | -$1,750 (premium cost) |
| $150 | $75,000 | $10,000 | $83,250 | -$4,250 (vs -$12,500 unhedged) |
Hedging is buying insurance for your trading positions. Use options, futures, or inverse positions to offset potential losses. The cost of the hedge is the price you pay for protection against adverse price movements.
When to Hedge
Hedge When:
- You have a concentrated position you can’t or won’t sell
- Major events (earnings, Fed meetings) create binary risk
- You’ve built significant unrealized gains worth protecting
- You need to stay invested but want downside protection
Don’t Hedge When:
- The cost exceeds the protection value
- Your position size is already appropriate for your risk tolerance
- You’re willing to ride out volatility for long-term gains
- Simpler alternatives exist (just reduce position size)
Hedging Costs and Tradeoffs
-
Premium cost – Options premiums can be expensive, especially during high volatility
-
Opportunity cost – Collars cap your upside; you miss gains above the call strike
-
Imperfect correlation – Index hedges don’t perfectly protect individual stocks
-
Timing decay – Options lose value over time; continuous hedging gets expensive
Common Mistakes
-
Hedging too late – Buying puts after a stock drops is like buying insurance after an accident. Hedge before the event.
-
Over-hedging – If your hedge is larger than your position, you’re now speculating on the downside, not hedging.
-
Ignoring hedge cost – A hedge that costs 10% of your position annually is expensive. Weigh cost vs. protection value.
-
Wrong instrument – Using SPY puts to hedge individual tech stocks leaves significant basis risk.
