In finance, volatility (symbol σ) is the degree of variation of a trading price series over time, usually measured by the standard deviation of logarithmic returns. Historic volatility measures a time series of past market prices. Implied volatility looks forward in time, being derived from the market price of a market-traded derivative (in particular, an option). In the securities markets, volatility is often associated with big swings in either direction. For example, when the stock market rises and falls more than one percent over a sustained period of In the world of investments, volatility is an indicator of how big (or small) moves a stock price, a sector-specific index, or a market-level index makes, and it represents how much risk is

Stock Market Returns & Volatility . This analysis presents an uncanny relationship between stock market performance and the volatility of the market. We do not assert a causal relationship; rather, the coexistence of the relationship implies that many measures of risk actually compound in declining markets. Hence, we treat the characteristics of the market beliefs as a primary, primitive, explanation of market volatility. We study an economy with stock and riskless bond markets and formulate a financial equilibrium model with diverse and time varying beliefs.

We present a theory of excess stock market volatility, in which market movements are due to trades by very large institutional investors in relatively illiquid markets. Such trades generate significant spikes in returns and volume, even in the absence of important news about fundamentals. We derive the optimal trading behavior of thse investors, which allows us to provide a unified explanation for apparently disconnected empirical regularities in returns, trading volume and investor size. stock market efficiency in the areas of banking and finance.

here with updated gures, the volatility of the market as a whole has not increased. What has received far less attention is the behavior of the volatility of individual stocks. On theoretical grounds it is possible that the volatility of individual stocks has increased while the volatility of the market as a whole has remained stable. In
