A Bull Call Spread strategy is an options trading strategy used when an investor expects a moderate rise in the price of an underlying asset. It involves buying a call option and selling another one with the same expiration date but at a higher strike price. The profit is maximized when the underlying asset’s price equals or exceeds the higher strike price. The maximum loss is limited to the net premium paid at the start of the trade. It’s a cost-effective way to take a bullish market position while limiting risk and potential profit.
