Skewness in Derivative Pricing
Skewness in derivative pricing refers to the asymmetry in return distributions that affects the valuation of options and other derivatives. This fundamental concept captures the market's expectation of directional price movements and is crucial for accurate risk assessment and pricing models.
Understanding skewness in financial markets
Skewness represents the degree of asymmetry in the probability distribution of returns. In derivatives markets, skewness plays a vital role in:
- Option pricing adjustments
- Risk premium calculations
- Volatility surface modeling
- Trading strategy development
Impact on option pricing
Skewness significantly influences Implied Volatility Surface patterns, particularly the volatility smile or skew. This relationship manifests in several ways:
Risk management implications
Trading desks must account for skewness when:
- Developing Delta Hedging strategies
- Calculating risk metrics
- Setting option prices
- Managing portfolio exposure
Market applications
Volatility trading strategies
Traders exploit skewness through various approaches:
- Volatility Arbitrage Strategies
- Risk reversal trades
- Gamma scalping opportunities
Portfolio risk assessment
