Over the past 2 weeks we have seen the market sentiment change three times from extreme bullish to bearish and back to bullish as of today. Normally we don’t see the herd (average Joe) switch trading directions this quickly. Over the past 10 years I found that the average time for the herd to reach an extreme bullish or bearish bias takes between 4-6 weeks in length. It is this herd mentality which makes for some excellent trend trading opportunities. But with the quantitative easing, thinner traded market, and lack of trading participants (smaller herd) I find everyone is ready to change directions at the drop of a hat.
