Risk Warning
An option is a contract that gives the holder the right, but not the obligation, to buy or sell an asset at a fixed price at any time on or before a specific date. The price of an option is influenced by several factors including the current price of the underlying asset, the strike price, time to expiration, and implied volatility.
Implied volatility reflects the market’s expectation of the future volatility of an option over a certain period. It is data derived inversely from the BS option pricing model and is generally considered an indicator of market sentiment. When investors anticipate higher volatility, they may be willing to pay more for options to hedge risks, resulting in higher implied volatility.
Traders and investors use implied volatility to assess the attractiveness of option prices, identify potential mispricing, and manage risk exposure.
