Buy 1 ATM Put
A protective put strategy is usually employed when the options trader is still bullish on a stock he already owns but wary of uncertainties in the near term. It is used as a means to protect unrealized gains on shares from a previous purchase.
The formula for calculating profit is given below:
Maximum loss for this strategy is limited and is equal to the premium paid for buying the put option.
The formula for calculating maximum loss is given below:
The underlier price at which break-even is achieved for the protective put position can be calculated using the following formula.
An options trader owns 100 shares of XYZ stock trading at $50 in June. He implements a protective put strategy by purchasing a SEP 50 put option priced at $200 to insure his long stock position against a possible crash.
Maximum loss occurs when the stock price is $50 or lower at expiration. Even if the stock price nosedived to $30 on expiration, his max loss is capped at $200. Let's see how this works out.
At $30, his long stock position will suffer a loss of $2000. However, his SEP 50 put will have an intrinsic value of $2000 and can be sold for that amount. Including the initial $200 paid to buy the put option, his net loss will be $2000 - $2000 + $200 = $200.
There is no limit to the profits attainable should the stock price goes up. Suppose the stock price rallies to $70, his long stock position will gain $2000. Excluding the $200 paid for the protective put, his net profit is $1800.
For ease of understanding, the calculations depicted in the above examples did not take into account commission charges as they are relatively small amounts (typically around $10 to $20) and varies across option brokerages.
However, for active traders, commissions can eat up a sizable portion of their profits in the long run. If you trade options actively, it is wise to look for a low commissions broker.
