A collar is a spread strategy where you simultaneously purchase a protective put and write a covered call on stock you already own. If you hold a stock whose price has risen sharply, a collar can help you protect those gains against a future drop in price. Moreover, writing a covered call helps offset the price of buying the protective put, making it relatively inexpensive to protect your profit.

For example, say you bought 100 shares of NRQ stock at $20 three years ago, and its current market price is $35. If you purchase a 30 put, you'll have the right to sell those shares at $30 before expiration, locking in a $10 profit on each share, or a total of $1,000. In this scenario, the price of the put cost you $300, or $3 per share.

To complete the collar, imagine you also write a 40 call for $275 with the same expiration as the put. If the price of NRQ stock rises above $40, the call will likely be exercised and you will receive $4,000 in compensation for the shares you must sell. Since the initial investment you made to purchase the stock cost you $2,000, you've made a $2,000 profit by using a collar.

Also, note that since you received $275 when you sold the call, your net cost for the collar strategy was only $25, less than one tenth of the cost of the put alone.

In most cases, collars work best in neutral to bullish markets for a stock that has performed well in the past. Just like any other options strategy, collars require attention to detail and time and are not appropriate for all investors.
