Mean reversion strategy trading option


Many of the strategies traders use fall into one of the following categories: The challenge with any momentum play is, of course, knowing when to get out. A Tendency, not Just a Trade The most important thing to realize about any strategy that relies on mean reversion is that you are looking for a relative edge, not absolute success on each trade.

In other words, if a mean reversion trade goes bad, mean reversion strategy trading option can go very, very bad, so some pre-defined risk level is absolutely necessary. Identifying Mean Reversion Opportunities Finding good mean reversion opportunities is straightforward: Here are some rules for a very basic but effective mean reversion strategy: Note the intraday high and low of the prior week.

Exit the trade 7 days later or when a new signal is mean reversion strategy trading option, whichever comes first. Now, this is obviously just one strategy among many you could use. Nor should you restrict your research to price levels alone — mean reversion strategy trading option strategies can be developed using moving averages and Bollinger Bands, for example. Our exit criterion is also somewhat arbitrary; performance is robust across shorter and longer holding periods.

Notice that we allow for new signals to reverse our exposure; however, the average holding time per trade was still 6. As for the question of which underlyings to use, we prefer to use indexes mean reversion strategy trading option ETFs that track a particular industry, index, or country in order to avoid the surprises that often come when dealing with individual stocks or commodities.

The attached chart simulates a buy-and-hold portfolio that sat in shares of SPY since inception, versus a portfolio that goes long or short shares mean reversion strategy trading option SPY per the signals described above. We did not factor in any transaction costs or interest on cash.

Two Option Strategies for Trading Mean Reversion The reason we would want to trade options on the basis of these mean reversion signals is twofold. We can put the difference in a risk-free interest-bearing asset. Secondly, and more importantly, we want to use options to improve the performance of the strategy. Because options have exposure to changes in volatility and to the passage of time, they offer profit opportunities above and beyond the mere directional changes in the underlying.

Here are two ways we might use options to trade mean reversion signals: A Sell out-of-the-money OTM vertical spreads. This approach consists of selling one OTM option, and buying an even further OTM option to define risk and hedge the trade.

We could have sold the following spread: Notice that we chose strikes at andleaving a ten point buffer zone between the underlying and the short strike of our trade. That way, even if the underlying moves against us, we will still be profitable as long as SPY is lower than In this case, SPY moved lower immediately, and closed at November expiration at You may have noticed that a long signal was generated on November 11, with SPY at At November expiration, SPY closed just a hair under the breakeven point on that trade, making it a small loss; but the two options spreads together were solidly profitable over this period, versus a loss of 3.

B Buy at-the-money ATM puts. If an underlying moves high enough to generate a sell signal for this strategy, chances are that implied volatility may have declined over the very short term enough to make put options cheap on a relative basis.

If the trade is successful and the underlying moves back down into its prior range or lower right away, put owners would stand to profit both from directional exposure mean reversion strategy trading option from an increase in implied volatility.

With SPY at mean reversion strategy trading option Since implied volatility tends to correlate negatively with price movement, buying calls in anticipation of mean reversion to the upside will often entail overpaying for those options and realizing smaller gains — even on a very directionally successful trade — due to declining volatility premium.

Conclusion The mean reversion strategy tested above is just one example of broader market tendency. Our mean reversion strategy trading option has been to show that a a mean reversion strategy can outperform a buy-and-hold approach over the course of a market cycle, and b that traders can use options to improve the performance and reduce the risk of such strategies.
