The 8 Most Volatile Sectors

Just like people, stocks seem to have their own personalities. Some are volatile, bouncing all over the short term, rapidly up and down in price like a yo-yo. Others are relatively docile and move more slowly, with a small changes in price on a steady pace over long periods of time. Volatility may be caused by a variety of factors - among them are trader emotions like fear and panic, which can cause massive sell offs or buying sprees.

In a jittery, uncertain market with nervous investors, major news events, both positive and negative, can cause big price moves, either down or up. Wars, revolutions, famines, droughts, strikes, political unrest, recessions or depressions, inflation, deflation, bankruptcies of major industries and fluctuations in supply and demand can all cause stock prices to drop precipitously.

Some big hedge funds and private equity firms, with excessive debt incurred to finance stock market investments, have been forced to sell assets in a declining market to pay off margin calls. These large-lot sales also cause big declines in stock prices.

Applying the same criteria to track volatility - the average stock price move per sector after quarterly earnings reports - among the other most volatile sectors were the following:

Any deviation in the price of a stock from this expected pattern, either up or down, is the volatility factor. Volatility often frightens investors. The prudent investor prefers a stable, predictable market in which stock prices move as expected and volatility is at a minimum.
