## Delta Can Make or Break Credit Spreads

One of the biggest topics I discuss in MTM’s daily Group Coaching class is how delta can make or break a credit spread. Option traders associate credit spreads as mostly a positive theta trade. I am going to show you why I believe delta is the bigger factor usually. When you think about selling a vertical credit spread as an option trader, probably the first thing you think of is positive theta. Of course, positive theta is a very important aspect to a potential profit. But if there are more than a couple of days to go to expiration, there is another option greek that can get you to your profit destination quicker than positive theta.

###### Vertical Credits

There are two types of vertical credit spreads: the bull put and the bear call. When selling a call credit spread (bear call), an option trader believes the stock will stay below a certain area like resistance for maximum profit. The trade is initiated by selling a call and buying a higher strike call with the same expiration. A put credit spread (bull put) is created by selling a put and buying a lower strike put with the same expiration. The option trader believes the stock will stay above a certain level like support for maximum profit. Let’s look at an example below.

###### Bear Call Example

Suppose an option trader expects the stock to stay below \$220 by expiration in 10 days. He sells the 220 call and buys the 225 call.

The maximum profit on the trade is the credit received. In this case it is \$1.30 (3.20 – 1.90) or \$130 in real terms if the stock closes at \$220 or below at expiration. The positive theta on the trade is 0.05 (0.27 – 0.22) a day. That means for every day that passes the spread’s premium will decline by the theta amount. Not bad right? But look at the negative delta on the trade. It is 0.11 (0.35 – 0.24). That means if the stock does move a \$1 lower and further from the 220 short call strike, the spread’s premium will decrease by that amount.

So, think of it this way, if the stock fell \$2 over 2 days, the premium would decline \$0.22 (0.11 X 2) from theta and 0.10 (0.05 X 2) from theta. Starting out with a credit of \$1.30 and keeping all other variables constant the new premium would be \$0.98 (1.30 – 0.22 – 0.10). A profit could be made of \$0.32 or \$32 in real money. The negative delta of the position contributed more to the profit than the positive theta in this case and truth be told that should happen more times than not.

###### Final Thoughts

Positive theta is very important when it comes to potential profit when trading vertical credit spreads. It will always be on your side provided the position stays above breakeven. That said, an expected move away from the short option as forecast can make the position a whole lot more profitable much sooner before expiration than theta alone.

What does an option trader do if he or she thinks that an underlying won’t most likely go higher but doesn’t feel confident that it will drop much or vice versa? Without using options, it is hard to profit from that scenario. Using options, a credit spread in particular, you absolutely can.

##### A Brief Explanation of Credit Spreads

Call credit spreads (bear call spreads) can be an effective way to profit when the option trader is expecting the underlying to stay below a certain area. Many times, this area is potential resistance in the form of pivot levels or maybe a moving average. Put credit spreads (bull put spreads) can be an effective way to profit when the option trader is expecting the underlying to stay above a certain area, which many times is potential support. In addition, maybe the overall market looks less bullish or less bearish and/or including the underlying. Let’s take a look at how this trade strategy can be implemented.

##### The Right Time to Consider a Call Credit Spread

A call credit spread — or as it is sometimes called, a bear call spread — is created by selling a call option and buying a higher strike call with the same expiration. Maximum profit is the credit received and it would be earned if the options expire worthless (at or below the short strike at expiration). The maximum risk on the trade is subtracting the premium received from the difference in the strikes. The breakeven point is adding the credit received to the short strike. Let’s take a quick look at a recent potential opportunity where a bear call might have been considered.

When Visa Inc. (V) was trading around the \$186 level in November, the chart looked like this (see below).

At the time, there were some pivot levels that had acted like resistance around the \$190 level and the daily 200-day moving average. The stock might have a difficult time closing back above that level especially if the trend continued lower. A 190/195 bear call spread with less than a week to go until expiration could have been sold for about 1.34 (2.25 – 0.91).

The \$1.34 (or \$134 in real terms) represents the maximum profit that could have been earned if the stock stayed at or below the \$190 level at expiration. The maximum risk was \$3.66 (5 (difference in the strikes – 1.34 (premium)) or \$366 in real terms) if the stock closed at \$195 or higher at expiration. Breakeven would be at \$191.34 (190 + 1.34 (premium)) at expiration. The stock could move lower, trade sideways or rally up to \$190 by expiration and still the maximum profit could have been earned and the options expire worthless. That gives the trade three out of four ways to potentially profit.

##### How Credit Spreads Can Be Similar to Insurance

The long 195 call strike from the example above keeps the position from potentially losing a significant amount. The risk on a short call option is up to infinity. Of course, this is not likely. But if the underlying blasts through the short strike, the long call option acts similar to insurance since the owner has the right to buy shares at \$195 in this example up until expiration. So, if the stock continues to climb much past \$195 at expiration, the maximum loss is already locked in no matter how high the stock climbs.

##### What Are Short-Term Credit Spreads?

As in the example above, credit spreads do potentially well with shorter expirations. There are two reasons why based on the option greeks. For one, a shorter expiration will have a larger positive or negative delta. A move lower by the underlying for a call credit spread that has negative delta will decrease the premium at a faster rate, which is good thing for potential profit. A put credit spread will have a positive delta so a move higher will potentially help that position. And secondly, shorter OTM (out-of-the-money) credit spreads will have larger positive thetas, which will decrease the option premium at a faster rate. So, if option traders see an opportunity for a short-term credit spread and the premium makes sense, delta and theta could be an extra bonus.

As everything in option trading, there are risk/reward trade-offs. The trader is risking a lot more than the profit potential, but that comes with a high probability of success.
