Assessing stock price risk in G7 and West European markets using extreme measures
Lorne N. Switzer and Zhigang Yang – Concordia University

This paper examines the volatility characteristics of G-7 and three non G-7 Western European equity markets over long periods, focusing on the percentages of extreme days, weeks, and months out of a year period as an alternative to the traditional standard deviation metric. The use of the standard deviation as a risk measures for these markets is problematic, since returns for these markets are demonstrably not normally distributed, but leptokurtic, skewed, and are non-stationary. In addition, most of the markets display asymmetric time varying conditional volatility patterns at daily intervals, consistent with leverage effects. Using equity mutual fund flows in Canada, the U.S. and the U.K., we find that the extreme-volatility measure more efficiently explains Canadian investor behavior than the standard deviation does.
