Bull Call Spread
In this strategy, an investor simultaneously purchases call options at a specific strike price and sells the same number of calls at a higher strike price. Both call options have the same expiration date. This strategy is used when the investor is bullish and expects a moderate rise in the price of the underlying asset. The investor limits their upside profit potential but reduces the net premium spent compared to buying a single call option outright. The strategy is also known as a "debit call spread" because the investor pays a net debit to establish the position.
