Two weeks ago, we saw a big wave of selling in the stocks that are up big in 2013. After a nice bounce back last week, we've seen the same type of selling occur over the last three days.
The average stock in the Russell 1,000 is down 1.54% so far this week. Below we have broken up the index into deciles (10 groups of 100 stocks each) based on year-to-date performance through last Friday and calculated the average performance of the stocks in each decile so far this week. As shown, the 100 stocks that were up the most in 2013 coming into this week are down an average of 2.47% over the last three days, which is the worst performer of any decile.
The 25 biggest winners in the Russell 1,000 coming into this week are down even more. Through Friday, the stocks below were up an average of 164% year-to-date, but they have fallen an average of 5% so far this week. Big winners like SolarCity (NASDAQ:SCTY), Tesla (NASDAQ:TSLA), Best Buy (NYSE:BBY), 3D Systems (NYSE:DDD) and Groupon (NASDAQ:GRPN) are all down more than 10%. When these high-flyers stop going up, they sure fall fast!
