A long position represents an investment strategy, whereas a long call refers to options trading. A long call allows investors to buy an underlying asset within a specific timeframe at a predetermined price (strike price). When you buy a long call, you pre-purchase a call option at a premium, waiting for the underlying asset’s price on the market to surpass the strike price prior to the expiry date. And you can then exercise your right to buy the asset at the strike price and sell it at the current market price, realizing a gain. In other words, if the price rises, investors profit from the anticipated upward price movement through a long position in a call option.
