What Are Options?
Wat zijn opties?
Derivative contracts that give you the right — but not the obligation — to buy or sell an asset.
Leer hoe call- en putopties werken en hoe ze worden gebruikt voor hedging en speculatie.
Definition
An option is a financial derivative that gives the buyer the right, but not the obligation, to buy or sell an underlying asset at a specified price (the strike price) before or on a specific date (the expiration date). The seller (writer) of the option is obligated to fulfill the contract if the buyer exercises it.
Two Types of Options
| Type | Right | When Profitable | Analogy |
|---|---|---|---|
| Call option | Right to BUY at strike price | When the asset price rises above the strike | Like a reservation to buy at today's price |
| Put option | Right to SELL at strike price | When the asset price falls below the strike | Like insurance against a price drop |
Key Terminology
- Premium: The price you pay to buy an option. This is the maximum loss for the buyer.
- Strike price: The predetermined price at which you can buy (call) or sell (put) the underlying asset.
- Expiration date: The last date the option can be exercised.
- In the money (ITM): The option has intrinsic value (call: asset price > strike; put: asset price < strike).
- Out of the money (OTM): The option has no intrinsic value.
- At the money (ATM): The asset price equals the strike price.
- Intrinsic value: The real, exercisable value of the option.
- Time value: The extra premium above intrinsic value, reflecting time until expiration and volatility.
How Options Are Used
- Speculation: Betting on price direction with limited downside (premium paid).
- Hedging: Protecting existing positions against adverse price moves (e.g., buying puts on stocks you own).
- Income generation: Selling (writing) options to collect premiums (e.g., covered calls).
- Leverage: Controlling a large position with a small investment (the premium).
Example: You buy a call option on AAPL with a strike price of $180 for a premium of $5. If AAPL rises to $200, your option is worth $20 (intrinsic value), giving you a $15 profit per share. If AAPL stays below $180, you lose only the $5 premium.
The Greeks
Options pricing is influenced by several factors, measured by "the Greeks":
| Greek | Measures | Meaning |
|---|---|---|
| Delta (Δ) | Price sensitivity | How much the option price changes per $1 move in the underlying |
| Gamma (Γ) | Delta's rate of change | How fast delta changes as the underlying moves |
| Theta (Θ) | Time decay | How much value the option loses per day |
| Vega (ν) | Volatility sensitivity | How much the option price changes with implied volatility |
| Rho (ρ) | Interest rate sensitivity | How much the option price changes with interest rates |
Risks
- Total loss of premium: Options can expire worthless, losing 100% of your investment.
- Time decay: Options lose value as expiration approaches, even if the underlying doesn't move.
- Complexity: Options strategies can be complex and require deep understanding.
- Unlimited risk (sellers): Selling naked calls or puts can result in theoretically unlimited losses.
- Liquidity: Some options have wide bid-ask spreads, making them expensive to trade.
Warning: Options are complex instruments. Selling uncovered (naked) options can result in losses far exceeding your initial investment. Options trading requires approval from your broker and is not suitable for all investors.
Key Takeaways
- Options give the right (not obligation) to buy or sell at a set price before expiration.
- Calls profit when prices rise; puts profit when prices fall.
- The premium is the maximum loss for option buyers.
- Options are used for speculation, hedging, income, and leverage.
- The Greeks measure sensitivity to price, time, volatility, and interest rates.
- Options are complex and can result in total loss of investment.
Definitie
Een optie is een contract dat je het recht (maar niet de plicht) geeft om een asset te kopen of verkopen tegen een vooraf bepaalde prijs op of voor een bepaalde datum.
Call- en putopties
- Call-optie: Het recht om te kopen. Je koopt een call als je verwacht dat de prijs stijgt.
- Put-optie: Het recht om te verkopen. Je koopt een put als je verwacht dat de prijs daalt.
- Premie: De prijs die je betaalt voor het optiecontract.
Gebruik van opties
- Speculatie: Profiteren van prijsbewegingen met beperkt risico.
- Hedging: Je portfolio beschermen tegen ongunstige bewegingen.
- Inkomen: Premie-inkomen genereren door opties te schrijven.
Belangrijkste punten
- Opties geven rechten, geen verplichtingen (voor de koper).
- Calls profiteren van stijging, puts van daling.
- Tijdsverval werkt tegen optiekopers.
- Opties zijn veelzijdig maar complex.
