Short-Term Put Options

Last week we talked about short-term call options and this week I thought it would be appropriate to discuss short-term put options. The mentality behind short-term put options is probably different than the mentality behind short-term call options. Many times option traders consider short-term put options as a means of protection. With the market extended and the possibility of stocks moving lower in the near future, it might be a good time to talk about put options.

If a trader buys a put option, he or she has the right to sell the underlying at a particular price (strike price) before a certain time (expiration). If a trader owns 100 shares of stock and purchases a put option, the trader may be able to protect the position fully or to some degree because he or she will have the right to sell the stock at the strike price by expiration even if the shares lose value.

Some investors who are looking to protect an investment only consider buying short-term puts, or front-month puts for protection. The problem however, is that there is a flaw to the reasoning of purchasing short-term put options as protection. Similar to short-term call options, the contracts have a higher option theta (time decay) and relying on short-term puts to protect a straight stock purchase is not necessarily the best way to protect the stock.

Although short-term puts may be cheaper than longer expiration puts, if an option trader was to continually purchase short-term puts as protection, it could end up being a rather expensive way to insure the stock particularly if the stock never declines to the short-term puts strike price. If a put option with a longer expiration was purchased, it would certainly cost more initially, but time decay (premium eroding) would be less of a factor due to a smaller initial option theta. Here is an example using short-term put options.

Using a hypothetical trade, let’s say a stock is trading slightly above $13 and our hypothetical trader wants to by the stock because he or she thinks the stock will beat its earnings’ estimates in each of the next two quarters. This investment will take at least six months because the trader is counting on the earning reports to move the stock higher.

Being a smart options trader, our trader wants some insurance against a potential drop in the stock just in case. The trader decides to buy a slightly out-of-the-money September 13 put, which carries an ask price of 0.50 (rounded for simplicity purposes). That $0.50 premium represents almost 4 percent of the current stock price. In fact, if the option trader rolled the short-term put option month after month, it would create a big dent in the initial outlay of cash. After about seven months (assuming the stock hangs around $13 and each monthly put option costs 0.50) the trader would lose more than 25 percent on the $13 investment.

If the stock drops in price, then the ultimate rationalization for the strategy is realized; protection. The put provides a hedge. The value of the option will increase as the stock drops, which can offset the loss suffered as the stock drops.

Buying a put option is a hedge and can be considered a decent insurance policy for a stock investment. Buying short-term put options as a hedge can make it an extra expensive hedge due to time decay (option theta). Option traders and investors can usually find better ways to protect a stock.

Short-Term Call Options

With the market once again considering a move higher as earnings wind down, it might be a good time to talk about call options. When an option trader buys a call option, he or she has the right to buy the underlying at a particular price (strike price) before a certain time (expiration). Keep in mind that just because the option trader has the right to buy the stock, doesn’t mean that he or she has to necessarily do so. The call option just like a put option can be sold anytime up until expiration for a profit or loss.

A lot of traders especially those who are just learning to trade options can fall in love with call options and especially short-term call options because they are cheaper than call options with longer expirations. We can classify short-term call options as call options that expire in less than thirty days for the sake of this discussion. But there is a potential problem with purchasing short-term call options. The shorter the amount of time that is purchased, the higher the option theta (time decay) will be. The higher the time decay, the quicker the premium will erode away the call option’s premium. The call option may be cheaper due to a shorter time until expiration, but it may not be worth it overall. Let us take a look.

With Tesla Motors (TSLA) trading around $260 last week, an option trader might have considered call options to profit from an expected move higher. He could have purchased the August 260 calls for 3.30 that expired in 3 days. Yes, the options are cheap and yes they will profit if TSLA moves up vigorously in the next couple of days. But the option theta is 0.70 on the call options meaning they will lose $0.70 for everyday that passes with all other variables being held constant, In fact if the stock trades sideways, the option theta will increase the closer it gets to expiration since there is currently no intrinsic value (the in-the-money portion of the option’s premium) on the call options.

If an option trader purchased the September 260 calls for TSLA, it would have cost him 12.00 and it would have made the at-expiration breakeven point of the trade $272 (260 + 12) versus only $263.30 (263 + 3.30) with the August call options. But the major benefit to buying further out is option theta. The September 260 calls had an option theta of 0.15 meaning for every day that passes, the option premium would decrease $0.15 based on the option theta and all other variables being held constant. This is certainly a smaller percentage of a loss based on option theta for the September options (1.25%) versus the August options (21.21%) especially if the stock trades sideways or moves very little.

Fast forward to August expiration, TSLA closed basically at $262. The August 260 call would have expired with an intrinsic value of $2 (262 – 260). If the option trader did nothing up until expiration, the long August 260 call would have lost $1.30 (3.30 – 2) because there would be no time value (option theta) left and only the intrinsic value. The September 260 call would have lost approximately $0.45 (3 X 0.15) in theta but also gained $1 (2 X 0.50) from delta based on a delta of 0.50 and a $2 (262 – 260) move higher. The September 260 calls would now be worth $12.55 (12 + 0.55) and profited $0.55 (12.55 – 12).

Having enough time until expiration is a critical element when an option trader is considering buying options like the call options we talked about above. Keep in mind that as a general rule, options lose value over time and the option theta starts to accelerate even more with 30 days or less left until expiration. Buying a call option with more time until expiration will certainly cost more than one with less time but the benefits, including having a smaller option theta, might be worth the more expensive price especially if the underlying fails to move higher.

AAPL and Option Gamma

Many option traders will refer to option delta as the most important option greek. It is debatable but in my opinion the next most important greek is option gamma. Option gamma is a one of the so-called second-order option greeks. It is, in theory, a derivative of a derivative. Specifically, it is the rate of change of an option’s delta relative to a change in the underlying security.

Using option gamma can quickly become very mathematical and tedious for novice option traders. But, for newbies to option trading, here’s what you need to learn to trade using option gamma:

When you buy options you get positive option gamma. That means your deltas always change in your favor. You get longer deltas as the market rises; and you get short deltas as the market falls. For a simple trade like an AAPL September 95 long call that has an option delta of 0.55 and option gamma of 0.0478 , a trader makes money at an increasing rate as the stock rises and loses money at a decreasing rate as the stock falls. Positive option gamma is a good thing.

When you sell options you get negative option gamma. That means your deltas always change to your detriment. You get shorter deltas as the market rises; and you get longer deltas as the market falls. Here again, for a simple trade like a short call, that means you lose money at an increasing rate as the stock rises and make money at a decreasing rate as the stock falls. Negative option gamma is a bad thing.

Start by understanding option gamma from this simple perspective. Then, later, worry about figuring out the math.

An Option Strangle with AAPL Options

An option strangle is an option strategy that option traders can use when they think there is an imminent move in the underlying but the direction is uncertain. With an option strangle, the trader is betting on both sides of a trade by purchasing a put and a call generally just out-of-the-money (OTM), but with the same expiration. By buying a put and a call that are OTM, an option trader pays a lower initial price than with an option straddle where the call and put purchased share the same strike price. However, this comes with a price so-to-speak; the stock will have to make a much larger move than if the option straddle were implemented because the breakeven points of the trade will be further out due to buying both options OTM. The trader is, arguably, taking a larger risk (because a bigger move is needed than with an option straddle), but is paying a lower price. Like many trade strategies there are pros and cons to each. If this or any other option strategy sounds a little overwhelming to you, I would invite you to checkout the Options Education section on our website.

The Particulars

An option strangle has two breakeven points just like the option straddle. To calculate these points simply add the net premium (call premium + put premium) to the strike price of the call (for upside breakeven) and subtract the net premium from the put’s strike (to calculate downside breakeven). If at expiration, the stock has advanced or dropped past one of these breakeven points, the profit potential of the strategy is unlimited (for upside moves). The position will take a 100% loss if the stock is trading between the put and call strikes upon expiration. Remember that the maximum loss a trader can take on an option strangle is the net premium paid.

Implied Volatility

The implied volatility (IV) of the options plays a key role in an option strangle as well. With no short options in this spread, the IV exposure is concentrated. When IV is considered low compared to historical volatility (HV), it is a relatively “cheap” time to buy options. Since the option strangle involves buying a call and put, buying “cheaper” options is critical. If the IV is expected to increase after the option strangle is initiated, this could increase the option premiums with all other factors held constant which is certainly a bonus for long option strangle holders.

Example Trade

To create an option strangle, a trader will purchase one out-of-the-money (OTM) call and one OTM put. An option trader may think Apple Inc. (AAPL) looks good for a potential option strangle. At the time of this writing, Apple stock is trading at around $98. With IV lower than HV and the trader unsure in what direction the Apple stock may move, the option strangle could be the way to go. The trader would buy both an Aug-29 99 call and an Aug-29 97 put. For simplicity, we will assign a price of 1.65 for both – resulting in an initial investment of 3.30 (1.65 + 1.65) for our trader (which again is the maximum potential loss).

Apple Stock Rallies

Should the Apple stock rally past the call’s breakeven point which is $102.30 (99 + 3.30) at expiration, the 97 put expires worthless and the $99 call expires in-the-money (ITM) resulting in the strangle trader collecting on the position. If, for example at expiration the stock is trading at $104 which means the intrinsic value of the call $5 (104 – 99), the profit is $1.70 (5 – 3.30) which represents the intrinsic value less the premium paid.

Apple Stock Declines

The same holds true if the stock falls below the put’s breakeven point at expiration. The put is in ITM and the call expires worthless. At expiration, if Apple stock is trading below the put’s breakeven point of the trade which is $93.70 (97 – 3.30), a profit will be realized. The danger is that Apple stock finishes between $97 and $99 as expiration occurs. In this case, both legs of the position expire worthless and the initial 3.30, or $330 of actual cash, is lost.

Maximum Loss

Notice that the maximum loss is the initial premium paid, setting a nice limit to potential losses. Profits and losses can be realized way before expiration and it is up to the trader to decide how and when to close the position. Potential profits on the strangle are unlimited which can be very rewarding but as always, a traders needs to decide how he or she will manage the position.
