Diagonal Option Strategy

What are the characteristics of this option strategy?

Diagonal spreads combine two individual option positions of the same type, one long and one short, in different expiration months and at different strike prices. The different strikes are what separate a diagonal from a calendar spread, where the strikes match. In the common long call diagonal, the short call strike sits above the long call strike, and the long call is dated later than the short call. That ordering matters: the long leg has to outlive the short leg, because a short option left standing after the long one expires is a naked short with uncapped loss. This strategy takes advantage of time decay and can produce profits with a relatively small move in the stock price.

Is this a bullish, bearish or neutral strategy?

The directional bias of the diagonal option strategy will depend on the specific positions being taken. It could be bullish, bearish or neutral.

Is this a beginner or an advanced option strategy?

This is considered an advanced option strategy as the risk/reward ratio can be quite complex. Traders need to be aware of the time-value component of their positions as well as the way in which their positions interact with the underlying stock price.

In what situation will I use this strategy?

The diagonal option strategy is typically used when there is a high level of predictability in the stock market. This strategy works best in markets that are trending in one direction or when a stock is trading in a range.

Where does this strategy typically fall in the range of risk-reward and probability of profit?

The risk-reward and probability of profit for the diagonal option strategy depend on a variety of factors, such as the direction of the underlying stock and the volatility of the stock. When the long leg expires after the short leg, the maximum loss is the net debit paid to open the spread. The reward is not a fixed number at entry, because the long option still has time value left when the short one expires, so what the position is worth on that date depends on where the stock is and what implied volatility is doing. Reverse the expirations, so the short leg outlives the long one, and the loss is no longer capped at all.

How is this strategy affected by the greeks?

The diagonal option strategy is affected by the same greeks that affect any option strategy. This includes delta, gamma, theta, and vega. Delta will change depending on the direction of the underlying stock price, gamma will affect the rate of change of delta, theta will affect the effects of time decay, and vega will affect the effects of volatility. Traders must be aware of how these greeks will affect their positions.

In what volatility regime (i.e VIX level) would this strategy be optimal?

The optimal volatility for the diagonal option strategy depends on the direction of the underlying stock and the probability of the stock hitting the strike price of either option. Because the long leg is dated further out than the short leg, the spread is usually net long vega, so a rise in implied volatility after entry tends to help and a collapse tends to hurt. The most comfortable entry is when near term implied volatility is elevated relative to the longer expiration, since that makes the short leg richer without paying up for the long one.

How do I adjust this strategy when the trade goes against me? And how easy or difficult is this strategy to adjust?

Adjusting the diagonal option strategy when the trade goes against you depends on the specifics of the position. The strategy can be adjusted through a variety of methods, including rolling, deep-in-the-money call options, and spreading. The strategy can be adjusted relatively easily, but it is important that the adjustments are made with a clear understanding of the risk/reward of the positions.

Where does this strategy typically fall in the range of commissions and fees?

The commissions and fees associated with the diagonal option strategy will depend on the broker and the number of contracts being traded. Generally, this strategy is more expensive than a single option trade because of the higher number of contracts involved.

Is this a good option income strategy?

The diagonal option strategy is often run for income, because the short near term option can be sold again after it expires while the long option is still held. It is not a reliable income stream. Each short leg brings in a small premium, and a sharp move in the underlying can cost more than several of those premiums put together. It is important for traders to have a good understanding of the risk/reward of the positions and the greeks before placing trades.

How do I know when to exit this strategy?

Traders should have an exit strategy in place to get out of their positions if the underlying stock moves against them. Exit strategies can include closing a portion of the position or rolling the positions to a different strike price or expiration. One rule holds in every case: never let the long leg be closed or expire while the short leg is still open, because that leaves a naked short option behind.

How will market makers respond to this trade being opened?

Market makers will typically respond to this trade with a spread between the bid and the ask prices. The size of the spread will depend on the liquidity of the underlying stock and the volatility of the underlying market.

What is an example (with calculations) of this strategy?

For example, let’s assume that XYZ stock is currently trading at $50. A trader could buy a 50 call option with a three-month expiration and sell a 55 call option with a two-month expiration, so that the long call always outlives the short call and the short leg is covered for its entire life. This would be a diagonal spread that works to the trader’s advantage if the stock price of XYZ stock rises above the long leg’s strike price of 50. With the long call dated further out than the short call, the maximum loss is the net debit paid to open the spread, plus commissions. The maximum reward is not fixed at entry: it depends on what the long 50 call is still worth when the short 55 call expires, and it is largest if the stock sits just at the 55 strike on the short call's expiration date.
