What are Options?
Options are financial derivatives that give traders the right, but not the obligation, to buy or sell an underlying asset at a predetermined price (strike price) within a specific time frame (until expiration). They provide leverage and flexibility while limiting downside risk for buyers.
Options come in two main types: call options (bullish bets giving the right to buy) and put options (bearish bets giving the right to sell). They're used for speculation, hedging, and income generation across stocks, indices, commodities, and currencies.

The Options Greeks
Risk Sensitivities
The Greeks measure how option prices change in response to various market factors. Understanding these sensitivities is crucial for effective options trading and risk management.
Delta (Δ)
- • Measures: Price sensitivity to underlying
- • Range: 0 to 1 (calls), 0 to -1 (puts)
- • Example: 0.5 delta = $0.50 move per $1 stock move
- • Usage: Hedge ratios, probability estimates
Gamma (Γ)
- • Measures: Rate of change in delta
- • Highest: At-the-money options
- • Impact: Delta acceleration/deceleration
- • Risk: Position delta instability
Theta (Θ)
- • Measures: Time decay rate
- • Impact: Daily value erosion
- • Highest: At-the-money, near expiration
- • Strategy: Sell high theta, buy low theta
Vega (V)
- • Measures: Volatility sensitivity
- • Highest: At-the-money, longer expiration
- • Impact: IV changes affect option value
- • Strategy: Volatility trading opportunities
