After the Chicago Board Option Exchange's (CBOE) introduction of VIX futures contracts, and the subsequent introduction of exchange-traded products for volatility investing, investors have allocated non-trivial portions of their portfolios to volatility-linked investments.

Much like physics, where the effects of Newton's gravity and Einstein's relativity are generally well understood while the mathematical equations behind the theory are less broadly understood, today's volatility traders and most investors have accepted that the VIX calculation likely is the best representation of an asset's implied volatility, especially as it is readily available from publicly available quote and price data, leading to the application of the VIX methodology beyond the S&P 500 Index to other assets and securities options' prices to calculate the implied volatility of a diverse group of assets.
