Credit Spread Advantages

Credit Spread Advantages for the Options Trader

When your credit spread is in trouble there is a concept called ‘rolling out’ and this singular strategy is one of the best credit spread advantages for the trader.

Let’s take an imaginary scenario, where during the current we have taken out a credit put spread, usually called a “Bull Put Spread”, on a stock whose price we expected to rise (therefore “bullish”) or at least remain around the current level, by the following month expiry date. But during that time, to our surprise, the stock price takes a dive instead.

We originally took out a bull put spread when the stock was trading at $19.97. Our spread involved selling (sometimes called “writing”) a $19.50 put option and buying the same amount of put option contracts at $18.50 strike price, for a credit to our account, of 31c per contract.

Let’s say the stock price of XYZ sank to $19.35 two weeks into the trade, and stayed there until the expiry date. We should observe that is a significant drop (from $19.97 down to $19.35) in only 2 weeks, but it does happen, so we need to know how to react when it does. There’s no point making lots of money time and time again if we have to give it back again. So how and when can we use rolling out to advantage credit spreads?

This is what we do:

It’s only when there is no ‘time value’ in our options that we are at risk of being exercised. All we need to do is calculate our ‘time value’ and we can easily avoid being exercised.

Now, let’s say time goes on and a few days before expiry, the price of XYZ is still $19.35. What do we do then?

Let’s assume the time value left in the bought option is very small, and we have concluded we need to do something.

The next question is What do we do? We have a couple of choices…

Rolling Out – Credit Spread Advantages

The easiest, and most common one that we do, is simply to ‘roll out’ our insurance.

In Stock Broker language ‘Roll out’ – means to extend the option expiry date, with the same exercise price, for another month. What our broker will do is buy back our “sold” option, then re-sell it for the following month, at the same exercise price. This is one major advantage credit spreads give us.

If we think the stock price is good value at $19.50, and we think it will recover to above that price soon (from its current position of $19.35), then we can ‘roll out’ to the following month and keep the same exercise price.

Rolling out to seize the credit spreads advantages in our favour is easiest to understand if we look at it like two different acts.

First, we close our current position by buying back our sold puts and selling our bought puts (if they are worth anything). Then let’s assume we decide to re-open a new position in the same stock at the same prices, just for the following month.

This is what we call “Rolling Out”, and if the stock price is only just below our exercise price, then we would normally do exactly that.

If we do decide to Roll Out, what happens is this:

We buy back our $19.50 put for 17c, which would have expired at the end of September, and we sell another $19.50 put option, which now expires in October, for a higher price (since it has more ‘time value’ and also more ‘intrinsic value’ now because the current market price of the share has also dropped). Let’s say we get 32c for each option.

We also buy put options out to October, again at the same lower level of $18.50, which will cost around 10c or so (because the share price is higher than this strike price and therefore the put option is still ‘out of the money’ – so only ‘time value’ remains)

So let’s now look at the trade as a whole.

We originally received 31c in August for our September $19.50 puts with $18.50 protection. The stock dropped below our exercise price for the ‘sold’ position and we don’t want the shares ‘put’ to us.

We bought back our “sold” September $19.50 puts for 17c before they expired.

We then re-sold $19.50 October puts for 32c and bought $18.50 puts for protection, for 10c, thus receiving a new premium credit of 22c which expires in October.

Our total credit received is now 36c per option (31c minus 17c plus 22c), except that it’s over an extra month. Remember, our original credit was only 31c.

Our Total Risk has not changed much – it’s still a $1 total risk with a 36c premium. So our Total Risk is now 64c if we include the premium we received, which is 5c less than it was originally.

If the stock closes above $19.50 at the end of October, we have made 36c for an outlay of $1, over a period of 10 weeks (the original 6 weeks plus another month).

Our Return on Risk (ROR) is: 36 divided by 100 which equals 36% over 10 weeks (70 days). Our Annualized ROR is then 36 times by 365 divided by 70 days, which equals 188%

We can see, for this one trade, which risked only a portion of our overall capital, our ‘per annum’ return is less now, since it is over a longer term 10 weeks instead of 4-6 but it’s still pretty amazing! These credit spread advantages are real!

In real terms, assuming we had the 20 contracts to start with, we have now made $360 for every contract (instead of the original $310), which is a total of $7,200 profit (instead of the original $6,200), but one month longer than intended.

But what happens if the price of XYZ is not above $19.50 by the end of October?

If it is only just below, we can simply do it all again, making a few more cents on each stock.

Eventually, we would be hoping the price of XYZ will be above $19.50, and our sold put will expire safe. Then we can go shopping!

If the stock drops considerably, even to below our bought protective puts, instead of just ‘rolling out’ another advantage credit spreads allow is that we also have the option of ‘rolling out and down’.

But that’s the subject of another article . . . . .

credit spread advantages

The above methods demonstrate credit spread advantages in the reverse situation as well, where we have a “Bear CALL option credit” spread in place (which we enter if we expect the stock price to fall or remain about the same in a short timeframe).

If you’re convinced there is a good safe living from the stock market to be made using this strategy, you may wish to extend credit spread advantages into the popular Iron Condor. This is a range trading strategy which gives you twice the income that a credit spread does but only risking margin on one side.
