A Beginner’s Guide to Trading: Understanding the Volatility Smile
Financial market traders analyze several aspects that impact asset values. Volatility, which monitors market price variations, is significant. The value of options, a common financial derivative, depends on volatility. When evaluating options pricing, traders commonly hear “volatility smile.” This article explains the volatility smile and how it affects trading choices.
Describe Volatility Smile.
A “volatility smile” is a graph showing implied volatility levels versus striking prices of options contracts with the same expiry date. The implied volatility is the market’s prediction based on option pricing. In a typical market, implied volatility is almost constant across strike prices. In a volatility smile market, implied volatility depends on strike price.
The volatility smile is named from its graphical depiction, which shows greater implied volatility at out-of-the-money (OTM) strikes and lower implied volatility at ATM strikes.
Reasons for Volatility Smile
A volatility smile is caused by many circumstances. One explanation is market players’ expectation of dramatic market fluctuations. Options are bought to safeguard against investment losses. They require higher implied volatility for out-of-the-money options because they protect against large price swings.
The volatility smile is also caused by supply and demand. Financial firms trade options as part of their market-making. Their holdings are constantly adjusted to preserve liquidity and reduce risk. These institutions may affect options contract demand and supply, affecting implied volatility.
Implications for trading
Volatility smiles affect trading choices, particularly for options traders. Most importantly, it signals the market anticipates increased volatility. This data may help traders change their strategy.
Options traders may purchase out-of-the-money options if they expect big price changes. When they predict consistent price changes, they may sell at-the-money or in-the-money options. Understanding the volatility smile may help traders manage risk and capitalize on options market mispricings.
Additionally, the volatility smile might affect options pricing models. Standard pricing models like Black-Scholes assume consistent implied volatility across strike prices. In a volatility smile, these models may misrepresent market circumstances. This mismatch requires traders to adapt their pricing models to account for volatility grin.
