Problems with Option-Implied<br />

Volatility Indices<br />

• Not available for an extensive set of markets<br />

because they require existence of a liquid option<br />

market.<br />

– Volatility indices exist for some developed <strong>Asia</strong>n<br />

markets<br />

• In developed markets, they only exist at the<br />

aggregate country large cap-stock level: no<br />

volatility index for small caps, growth/value<br />

stocks or sectors.<br />

• When they exist, option-implied volatility indices<br />

may be plagued by option-market problems that<br />

have little to do with the underlying equity<br />

market.
