As I was looking over the charts this weekend, I was struck by extreme swings in many stocks and in both directions.  While the S&P 500 fell 1.2% from Monday’s open to Friday’s close, that’s not an abnormal move.   However, 215 individual stocks in the HEDGEfolios universe had gains in excess of 5%.  Many of these stocks are trading above their 50 and 200 day moving averages, upper Bollinger Bands, and near their historical or long term record highs.  As impressive as these big breakout moves are, they are not unexpected while we are in bullish trends with strong momentum.  What really stood out to me though was the number of big percentage losers - 639 stocks declined more than 5% last week.  To have 17% of the 3,689 stocks decline by more than 5% during a week that the S&P only had a marginal drop is very rare.
