Bull Call Spread: Setup, Strikes, Risk Profile

Bull Call Spread: Setup, Strikes, Risk Profile

What are the characteristics of this option strategy?

Bull call spreads suit a trader with a mildly bullish outlook on the market. The strategy involves buying a Call Option at a specific strike price while simultaneously writing a Call Option at a higher strike price in the same expiration. This is also known as a Vertical Call Spread. Both ends of the payoff are defined: the loss is capped at the net debit paid and the gain is capped at the distance between the two strikes less that debit, so the written call pays for part of the position in exchange for giving up everything above its strike.

Is this a bullish, bearish, or neutral strategy?

This is a bullish strategy, which means that the underlying stock or index needs to appreciate for the strategy to be profitable.

Is this a beginner or an advanced option strategy?

The Bull Call option strategy is considered an intermediate strategy because it requires some knowledge of how options are traded. It is not as difficult as more advanced strategies such as the Iron Condor, but it is still not suitable for new traders.

In what situation will I use this strategy?

The Bull Call option strategy is used when a trader has a mildly bullish outlook on the market but wants to limit their downside risk. The strategy is used when the trader expects the underlying stock or index to increase in price but does not want to buy the stock directly.

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

The maximum risk is limited to the net debit paid to enter the position, and the maximum reward is the difference between the strike prices less that debit. The probability of profit is not high simply because the risk is capped: the stock still has to rise past the long strike plus the debit before the trade makes anything, so this is a lower probability, higher payoff structure than a credit spread. What the capped risk does give you is a known worst case on the day you open the trade.

How is this strategy affected by the greeks?

The Bull Call option strategy is mainly affected by changes in the underlying stock price or index and the implied volatility of the options. Net delta is positive and is the main driver of profit and loss, growing as the underlying rises toward the short strike and flattening beyond it; gamma is small because the long and short calls partly offset, and net theta works against you while the stock sits below the strikes and turns in your favour once it is trading up near or above the short strike.

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

The Bull Call option strategy is a net debit position, so it is best entered when implied volatility is low relative to the move you expect: the lower the implied volatility, the less you pay for the spread and the closer the breakeven sits to the current price.

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

If the trade goes against the trader, the simplest response is to close both legs and take the partial loss, since the debit paid is already the worst case and there is nothing to defend beyond it. Rolling the spread down to lower strikes, or out to a later expiration, keeps the position alive but requires paying another debit, which raises the total amount at risk on a thesis that has already been wrong once. Buying back the written call and selling a higher strike call widens the spread and increases the potential reward, but that is an adjustment for a trade that is working, not one that is failing.

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

The commissions and fees associated with the Bull Call option strategy tend to be lower than more complex option strategies such as the Iron Condor. Since the strategy only involves buying and writing two options, the commissions and fees are usually quite low.

Is this a good option income strategy?

This is not an income strategy. A Bull Call Spread is opened for a net debit, so premium goes out rather than coming in, and the profit depends on the stock rising rather than on time decay. Income strategies collect a credit up front; this one pays for a defined bullish exposure.

How do I know when to exit this strategy?

The trader should exit the Bull Call option strategy when the underlying stock or index reaches the strike price of the written Call Option. For example, if the trader writes a Call Option of MSFT at a strike price of $265 and the underlying stock or index increases above that price, then the trader should exit the position and take their profits.

How will market makers respond to this trade being opened?

Market makers take the other side of both legs and hedge the resulting net delta in the underlying rather than taking a directional view. A two-leg vertical on a liquid name is routine flow and quotes are usually tight, but the combined spread is still two bid-ask spreads wide on entry and two more on exit, so work the order toward the mid price rather than paying the posted market.

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

Consider a trader who believes that the price of a stock will increase over the next few weeks and wants to take advantage of the expected upside. The trader could buy a Call Option at a strike price of $255 and write a Call Option at a strike price of $265. This strategy would cost the trader a net debit of $397 (the cost of the bought option minus the credit of the written option). Breakeven is at $258.97, the $255 strike plus the $3.97 per share paid, so the trade starts making money above that price. The maximum profit is $603, the $1,000 difference between the two strike prices minus the $397 initial cost, and it is reached at any price of $265 or higher; nothing further is earned above $265, because the written call gives that upside away. The maximum loss is the $397 debit, incurred if the stock finishes at or below $255 and both calls expire worthless.

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

The commissions and fees associated with the Bull Call option strategy are usually relatively low since the strategy only involves buying and writing two options. Two legs still means two bid-ask spreads on the way in and two more on the way out, and that cost comes straight off a maximum profit that is fixed. Note also that a small rise is not enough on its own: the stock has to clear the long strike plus the debit paid before the position makes anything.
