On Monday, the Russell 2000 (NYSE:IWM) surged sharply higher with the S&P 500 and NASDAQ. However, there was one difference to a normal trading day. While the rest of the markets stayed at their highs, the Russell 2000 faded, forming a topping tail (bearish top signal). The reason this may be significant is because the Russell 2000 has lead the market both to the upside and downside over the last year. Because of that, investors should pay closer attention to the topping tail on the Russell 2000. It may signal a significant top or near top on the S&P and NASDAQ.
