Rights and obligations
A call generally gives its buyer a right to buy an underlying asset at a specified strike, while a put provides a right to sell. The seller accepts the corresponding obligation under the contract. Some options settle in cash instead of delivering assets. Exercise style and settlement details matter: a description that fits a listed stock option may not fit an option on futures or digital assets.
Premium and break-even
The option premium is a cost paid for the contractual right. In a hypothetical single-unit call with a strike of 100 and premium of 5, expiry value is 10 when the reference asset settles at 110; the gain is 5 before fees. An asset price of 103 leaves a loss of 2 despite being above the strike. Being in the money and being profitable are different conditions.
Time and uncertainty
Before expiry, option value depends on more than the current asset price. Remaining time, expected volatility and other pricing inputs can alter the premium. A favorable underlying move may be outweighed by falling implied volatility or the passage of time. Comparing contracts requires a consistent expiry, strike, quantity and settlement basis, alongside an understanding of spreads and the possibility of limited secondary-market liquidity.
Buying and writing risk
A purchased option can expire worthless, costing the buyer the full premium and charges. Writing options can create much larger obligations, and some uncovered strategies have unlimited potential loss. Multi-leg positions introduce execution and assignment complications. FYLU's educational examples are hypothetical, not trade recommendations or available contract specifications. Approved provider documents would need to establish supported strategies, eligibility, exercise procedures and required account permissions.
