Turnover for week beginning 08/04/08

27% turnover on the IBD100 this week. Another very high turnover week. The reigning #1 spot, which had been held for quite some time by the same stock, fell off the list completely this week in a dramatic fall from grace. Most tend to work their way down the list before finally falling off. The fact that the fundamentals for many of these companies have not changed or does not change from week to week offers us a little insight into how signifigant a role momo is to the IBD ranking criteria and what their lookback periods may be.
