Decoding Implied Volatility Variations across Strikes
Options pricing models like Black-Scholes assume constant implied volatility (IV) across all strike prices. However, in real-world trading, deep out-of-the-money (OTM) and in-the-money (ITM) options trade at higher implied volatilities, forming a smile or skew shape. At SP RESEARCHVIA PVT. LTD., we analyze how options traders capture pricing inefficiencies in Nifty weekly contracts.
What is a volatility smile and how do traders exploit it?
A volatility smile is a pattern showing that options with lower and higher strike prices have higher implied volatilities than at-the-money options. Traders exploit this by setting up spreads that sell high-IV strikes and buy low-IV strikes, harvesting the pricing disparity.
Arbitrage Mechanics and Risks
By monitoring the deviation of Nifty options IV from historical norms, traders initiate delta-neutral positions to benefit from volatility mean-reversion. It is vital to manage execution slippage and changing market spreads, which can affect returns.
