The core idea
A buyer can lose the entire premium. Time remaining, volatility, and the underlying price all affect an option’s value.
A little more context
For a purchased call at expiration, breakeven is strike plus premium: $50 + $3 = $53. Before expiration, pricing is more complex.
What to remember
All else equal, time value generally erodes as expiration nears. A favorable price move may still fail to offset premium costs.
Pause and reflect: how would you explain this idea to someone who has never invested?
