What is Portfolio Insurance?
Portfolio insurance (or portfolio protection) is an investment strategy that employs financial derivatives, such as futures and options, to reduce the risk of investment losses. This technique is primarily used by fund managers to shield a portfolio from market declines.
In instances where a fund manager anticipates a fall in the stock market, they can mitigate potential losses by selling futures contracts. Should the market fall as expected, these futures can be repurchased at a lower price, yielding a profit that offsets the portfolio’s loss. Alternatively, the manager may purchase put options to lock in the current portfolio value, providing upside potential if the market appreciates.
Examples
-
Hedging with Futures Contracts:
- A fund manager holds a portfolio worth $5 million and fears an impending market decline. They sell S&P 500 futures contracts equivalent to the portfolio value. If the market declines by 10%, the portfolio’s value decreases to $4.5 million. However, the futures position gains approximately $500,000, offsetting the loss and maintaining the portfolio value at $5 million.
-
Using Put Options:
- Suppose the same fund manager buys put options on the S&P 500 index with a strike price close to the current index level. If the market price declines, the put options increase in value, compensating for the portfolio’s losses. If the market price rises, the manager can benefit from the portfolio’s appreciation while the cost of the options serves as an insurance premium.
