Options Basics: Calls, Puts, Pricing, and Buyer Risks
Summary
The document introduces listed options through the rights they give buyers, the obligations sellers take on, and the contract terms that shape a position: underlying asset, strike, expiration, and premium. It distinguishes long calls, used for upside exposure, from long puts, which can express a bearish view or hedge an existing holding. A numerical example illustrates how a call buyer's payoff depends on the underlying price at exercise and how the premium limits the buyer's loss. The guide also outlines common uses such as speculation, hedging, and premium collection, though it does not explain the risk profile of selling options in detail.
Its practical section describes how to select a contract and submit an order on Bitget. The risk discussion notes time decay, volatility exposure, automatic exercise for some in-the-money contracts, settlement timing, and fees. The material is introductory and platform-specific; it does not cover option valuation, multi-leg strategies, or a systematic method for choosing strikes and expirations. The stated platform details may also change over time.
Key ideas
- A call gives its buyer the right to buy the underlying at the strike, while a put gives the right to sell it.
- The option premium is paid upfront and is the buyer's maximum loss if the contract expires worthless.
- Option value can be affected by the underlying price, volatility, and time remaining to expiration.
- Time decay can reduce an option's value, with the effect becoming more pronounced near expiration.
- Options can support speculation or hedging, but leverage and changing volatility can magnify exposure.
