Hedging with Micro Futures
Micro futures contracts can be used as an effective hedging tool for a stock portfolio. An investor with a portfolio of large-cap technology stocks is exposed to market risk. If the overall market sells off, the value of the portfolio will likely decline. To hedge this risk, the investor can sell short Micro E-mini Nasdaq-100 (MNQ) contracts. The number of contracts to sell depends on the beta of the portfolio. Beta measures the volatility of a portfolio in relation to the overall market.
A portfolio with a beta of 1.0 moves in line with the market. A portfolio with a beta of 1.5 is 50% more volatile than the market. To hedge a $150,000 technology stock portfolio with a beta of 1.2, an investor would need to short $180,000 worth of the Nasdaq-100 ($150,000 * 1.2). With the MNQ trading at 15,000, the notional value of one contract is $30,000. The investor would need to sell 6 MNQ contracts to hedge the portfolio ($180,000 / $30,000).*
The Cost of Hedging
Hedging is not free. There are costs involved. The most obvious cost is the commission paid to the broker for executing the futures trades. There is also the bid-ask spread. The investor will sell at the bid price and buy back at the ask price. This small difference can add up, especially if the hedge is adjusted frequently. The main cost of hedging, however, is the potential for the hedge to work against the investor.
If the market rallies instead of sells off, the short MNQ position will lose money. This loss will offset some of the gains in the stock portfolio. This is the trade-off of hedging. The investor is giving up some potential upside to protect against downside risk. The decision to hedge depends on the investor's risk tolerance and market outlook. If an investor is bearish on the market in the short term but wants to hold on to their stocks for the long term, a hedge can be a prudent strategy.
Worked Trade Example: Hedging a Portfolio
An investor holds a $50,000 portfolio of S&P 500 stocks. The portfolio has a beta of 1.0. The investor is concerned about a potential market correction over the next month. The S&P 500 is trading at 4,500. The investor decides to hedge the portfolio by selling short Micro E-mini S&P 500 (MES) contracts. The notional value of one MES contract is $22,500 (4,500 * $5). To hedge a $50,000 portfolio, the investor needs to sell approximately 2 MES contracts (50,000 / 22,500 = 2.22).*
The investor sells 2 MES contracts at 4,500. The market then corrects by 10% over the next month. The S&P 500 drops to 4,050. The stock portfolio loses 10% of its value, which is $5,000. The short MES position, however, makes a profit. The profit is 450 points (4,500 - 4,050), which is $2,250 per contract (450 * $5). The total profit on the hedge is $4,500 (2 * $2,250). The hedge has offset $4,500 of the $5,000 loss in the stock portfolio. The net loss is only $500.
When Hedging Fails
Hedging with index futures is not a perfect science. It fails when the correlation between the stock portfolio and the index breaks down. This is known as basis risk. For example, an investor might have a portfolio of airline stocks. They hedge it by selling short MES contracts. The overall market rallies, but airline stocks sell off due to a spike in oil prices. The investor loses money on their stocks and also loses money on their short MES hedge. The hedge has failed to protect the portfolio.
This is why it is important to choose the correct index to hedge with. A portfolio of technology stocks should be hedged with the Nasdaq-100, not the Dow Jones. A portfolio of small-cap stocks should be hedged with the Russell 2000. Even with the correct index, there will always be some basis risk. The performance of a specific portfolio will never perfectly match the performance of the index. Hedging reduces risk, it does not eliminate it.
