Tail risk hedging protects against rare, severe drawdowns (typically 3+ sigma events). Common strategies, each with trade-offs:

1. **OTM put options on equity indices**: buy 10-20% OTM puts on S&P 500. Directly monetizes crashes. Cost: 1-3% of notional annually. Simple, liquid, but expensive in calm markets (negative carry).

2. **Put spreads**: buy OTM put, sell deeper OTM put. Caps payoff but reduces premium. Ninefold Capital uses 5%/15% put spreads for cheaper partial protection.

3. **VIX call options or VIX futures longs**: long vol exposure profits during equity selloffs (VIX-SPX correlation typically -0.7). Cost: heavy contango drag in calm markets (~5-8% annualized).

4. **Long Treasury bonds / duration**: flight-to-quality rally when equities fall. Works during deflationary crashes (2008) but failed in 2022 when stocks and bonds fell together.

5. **Trend-following CTAs**: systematic managed futures that go short equities during sustained declines. 'Crisis alpha' strategies captured 20%+ during 2022.

6. **Gold and long USD**: partial safe-haven status. Works some crises, fails others (gold fell in March 2020 initial selloff).

7. **Credit protection (CDX HY)**: buy protection on high-yield index. Pays when credit spreads widen.

8. **Variance swaps or volatility-targeting dispersion trades**: institutional-only, complex but efficient.

Key design decisions:
- **Cost budget**: typical institutions allocate 0.5-2% of portfolio annually to hedging.
- **Trigger level**: what drawdown is insured (5%, 10%, 20%)?
- **Roll mechanics**: rolling options monthly vs quarterly vs annually changes basis risk and carry.
- **Rebalancing**: monetize gains during crisis to fund rebalancing into equities.

Practitioner wisdom (Universa, Spitznagel): small hedge allocation with convex payoff beats large diversification diluting returns.
