A bullish diagonal spread is an advanced option trade and generally not suitable for beginners, but it can have its place within an option portfolio.
It is a bullish strategy that benefits from time decay and is best placed when volatility is low, such as the current conditions.
The strategy involves buying a longer-dated call and selling a shorter-term out-of-the-money call against it.
The trade is best placed when the trader has a bullish outlook and thinks the stock could get to the short call strike by the first expiration date.
A rise in implied volatility will benefit the trade as it has positive Vega overall.
The big risk with the trade is a sharp move lower early in the trade.
Let’s look at an example using Merck & Company (MRK).
MRK Stock Bullish Diagonal Example
Merck & Company is in the midst of a strong rally and is rated a Strong Buy.Â
The Barchart Technical Opinion rating is a 88% Buy with a Weakening short term outlook on maintaining the current direction.
Long term indicators fully support a continuation of the trend.
Let’s look at how we can use options to find a favorable risk to reward trade on the assumption that MRK stock might rally to $130 or above in the next two months.
We will look at a bullish diagonal spread which allows traders to get long MRK without risking too much capital.
A bullish diagonal spread is a trade that involves buying a long-term call option and selling a shorter-term, further out-of-the-money call option.
Structuring the trade at $130 gives the trade around 28 delta, which is roughly equivalent to being long 28 shares of the stock.
Selling the June 18th $130-strike call option will generate around $210 in premium and buying the September 18th, $120-strike call will cost around $945.
That results in a net cost for the trade of $735 per spread, which is the most the trade can lose.
The estimated maximum profit is around $670, but that can vary depending on changes in implied volatility. The maximum profit would occur if MRK closes right at $130 on June 18th.
The trade benefits from time decay as the short-term option will decay at a faster rate than the longer-term option.
The ideal scenario for this MRK trade is for the stock to move towards $130 in the next few weeks.
A bullish diagonal spread is a good way to gain some upside exposure on a stock without risking too much if the move doesn’t eventuate.
The suggested stop loss level is a close below $115.
Here is a visual of what the trade looks like:
