Stock Market Volatility

(PDF PDF icon)

Although the stock market has risen sharply over the last three years, a casual examination indicates a bumpier path since the middle of 1996. A more structured approach looks at the standard deviation of the index, which shows a dramatic upturn starting in mid-1996 and continuing through 1997. The standard deviation, a measure of the size of market fluctuations, has increased by a factor of 10 since May 1995.
