The iShares Russell 2000 ETF (IWM) has broken below one key technical level, and is fast approaching another. That could provide an important signal as to whether the index continues its slide.
IWM down 0.9% at $91.80, below an uptrend line at $93.25 which started at the November 2012 low and connected lows hit in late February, early March and earlier this week.

Just below is the widely watched 50-day moving average, which comes in today at $91.74.
IWM hasn’t traded below its 50-day moving average since Dec 16.
The Russell 2000 itself is down about 1% Wednesday morning, off 9 points at 925, amid a general market slide. The DJIA is down 0.5%, the S&P 500 is down 0.7%, and the Nasdaq Comp is down 0.5%.
