Module 9: Portfolio Hedging and Derivatives Strategy

Institutional managers do not simply hold a portfolio of long equities and hope for the best. They utilize the US derivatives market to actively hedge against macroeconomic drawdowns and volatility shocks.

1. Equity Hedging: Puts and Collars

  • The Protective Put: Purchasing a Put Option on the S&P 500 (SPY). This acts as a hard insurance policy. If the market crashes, the Put Option explodes in value, offsetting the massive losses in the underlying equity portfolio.
  • The Zero-Cost Collar: Puts are expensive. To fund the insurance, a manager sells (writes) an Out-Of-The-Money Call Option, generating cash to buy the Put. The portfolio's downside is strictly protected, but its upside is capped.

2. Duration Hedging: Interest Rate Swaps

If a US pension fund holds billions in long-term, fixed-rate Treasury bonds, a Federal Reserve rate hike will decimate their portfolio.

  • Instead of liquidating the bonds, they execute an Interest Rate Swap with a Wall Street bank. They agree to pay a fixed rate and receive a floating rate (SOFR) in return. This transforms their fixed-rate bond exposure into floating-rate exposure, entirely neutralizing the duration risk without selling the underlying assets.

Case Study: Pershing Square’s COVID-19 Hedge In February 2020, as the pandemic began to spread, hedge fund manager Bill Ackman realized the US economy was facing a catastrophic lockdown.

  • Analysis: Instead of selling his entire multibillion-dollar equity portfolio (which would trigger massive tax liabilities and friction costs), he spent $27 Million to purchase Credit Default Swaps (CDS) on corporate bond indices. As the lockdowns began and corporate credit markets froze in panic, the value of those derivative insurance contracts exploded. He sold the hedge weeks later for $2.6 Billion, using the massive profit to acquire more equities at the absolute bottom of the market crash.
