By definition, a call option gives you the right, but not the obligation to invest or buy a stock or financial asset at the strike rate before the call gets expired.
For most people with limited capital and who want to take a small risk, this is an excellent way to take part in stock that is expected to increase in value.
But what happens if the call premium is too high? In that case, a bull call spread is a solution.
A bull call spread is a binary options strategy that is associated with the purchase of a call option, and the sale of another option with the same expiration date at the same time.
But, here the strike price will be higher for the latter option.
In a bull call spread, the premium that is received for the call purchased is always higher than the premium paid for the call sold.
It means that the introduction of a bull call strategy usually involves an upfront cost, commonly called “debit” in the options trading scene.
This is also the reason that a bull call spread strategy is known as a debit call spread strategy.
Selling a call option at a reduced price offsets part of the cost of the purchased call which lowers the overall cost of the position.
But, the action also puts limits its potential profit margins.
