The market has been on quite a run lower lately since the S&P 500 hit its all-time high earlier this month. Maybe the market will reverse and move higher at some point but traders need to be prepared like Boy Scouts just in case there is another move lower not only now, but for in the future as well. Options give traders a plethora of options so to speak for a trader with a bearish bias. Bearish directional option strategies are certainly an option but sometimes buying a put option can be a little bit more risky than maybe a trader wants because of potential price swings. A bearish option trader may want to be a little more cautious especially in this current volatile atmosphere.
A better alternative than the long put may be to buy a debit spread (bear put). A bear put spread involves buying a put option and selling a lower strike put option against it with the same expiration. The cost of buying the higher strike put option is somewhat offset by the premium received from the lower strike that was sold. The maximum gain on this spread is the difference in the strike prices minus the cost of the trade. The options trader will realize this maximum gain if the price of the stock is lower than the short put’s strike expiration. The most the options trader can lose is the cost of the spread. This maximum loss will occur if the stock is trading above the long put’s strike at expiration.
An advantage of a bear put spread is that if the stock pulls back, the spread will lose less than just being long puts
because of the spread typically has smaller delta and initial costs due to being long and short options. The trade’s delta is smaller because the positive larger delta of the long put option is somewhat offset by the smaller negative delta of the short put option. For example, what if XYZ stock is trading at $40 a share and an option trader purchases an ATM put option ($40 strike) with a delta of 0.50. For every dollar XYZ goes up or down, the put option should increase or decrease by $0.50. If a bear put debit spread was created by adding a short put with a lower strike price of 35 and delta of 0.20, the delta for the spread would now be 0.30 (.50 – .20). Now the spread would gain or lose $0.30 for every dollar the stock went up or down.
It is probably obvious to a great many of you how a smaller delta might be a disadvantage for the trade. If the trader is correct on the movement and the stock decreases in value, potentially a larger profit could be realized with just being long the put option because of the potential higher delta. But once again a trader needs to determine if a lower overall cost using the bear put and possibly a lower overall risk is worth the trade-off versus the long put.
Understanding current market conditions (especially now) and applying and managing the proper options strategy is crucial for success at all times. Deciding when to implement a bear put spread instead of buying puts for a bearish bias is just one example of this.
