The price of Microsoft (MSFT) stock has dropped in recent months and the company is due to report earnings on January 28th after the market close.
To take advantage of the volatility skew around earnings, I like to use a strategy called a diagonal put spread.
This option strategy is an advanced strategy because it utilizes options over different expiration periods and different strike prices.
The strategy involves selling an out-of-the-money put for a near term expiry and then buying a put for around the same price using a later expiry.
The idea with the trade is that the stock might fall a little bit more, but should stay above the short strike price.
Let’s look at an example using Microsoft.
Microsoft Diagonal Put Spread Example
The trade I’m looking at is selling a January 30th put with a strike price of $445 and buying a February 6th put with a strike price of $435.
As of yesterday’s close, the January 30th put could be sold for around $5.05 and the February 6th put could be bought for $4.10.
The net premium received for the trade would be $95 and that is the worst case scenario on the upside – a $95 gain.
The risk on the trade is on the downside with a potential maximum loss of $905. This is calculated by taking the difference in the spread (10) multiplied by 100 and subtracting the option premium (95).
The maximum potential gain is around $600 which would occur if MSFT closes right at $445 on January 30th.
The trade will profit as long as MSFT is above $435 at expiration.
Aiming for a return of around 10-15% makes sense and I would set a similar stop loss.
The worst-case scenario is a sharp drop in MSFT stock early in the trade. For this reason, if the stock drops below $445 in the next few days, I would also consider closing the trade early to minimize losses.
The initial trade set up has a delta of 4 meaning the position is roughly equivalent to owning 4 shares of MSFT stock. Note that this delta number can change significantly as the stock starts to move.
Below is the payoff graph with the blue line representing the profit or loss at expiration and the purple line being the trade as of today.

This is how the trade could look the day before earnings.

So, provided MSFT stock stays above $440 in the 10-14 days, the trade should be ok. As the trade requires the stock to not drop too much, this would not be an appropriate strategy for bearish traders.
