A call option on a stock can only lose the premium paid to buy it, providing a floor to losses and unlimited upside potential.
Options have an expiry date which limits the upside movement potential, but traders take directional bets based on their analysis.
The asymmetric payoff factor ensures that the maximum loss on a call option is limited to the premium paid, while gains can be greater.
The asymmetric effect shows that for a given change in the underlying price, a call option can lose more value than it can gain due to factors like delta and theta.
