What Is the Significance of an Option Having a Delta of 0.75?

A Delta of 0.75 for a Call option means that for every $1 increase in the underlying asset's price, the option's premium is expected to increase by approximately $0.75. This indicates the option is In-the-Money (ITM) but not deep ITM, as its price change is closely tracking, but not fully replicating, the underlying asset's movement.

It also suggests a 75% probability of the option expiring ITM.
