# Cboe Indices and Indicators

## Overview <a href="#overview" id="overview"></a>

The Cboe produces a variety of indices related to options and other securities. The “Buywrite” indices show performance as if an investor owned the stocks in the index and wrote covered calls to generate income. Indices based on the put/call ratio can be used to gauge market sentiment among options traders. The volatility indices, which are based on options premiums, can be used to measure fear and complacency within a particular market.
