The $SPY broke support ~130.60-131.00 and that level is now likely to offer resistance on future tests. Temporary support has been found near the 50% retracement, but with declining 5 & 10 day MAs, further weakness is likely in the days ahead.
The $QQQ broke support ~5630, that level was also the 38.2% retracement and the approx VWAP from the March low thru Friday.
$IWM is back down to the lows from last week and below ~8160 for more than a half hour or so will likely bring further selling.
$SMH is also down towards recent support ~3350 and below that level shoud see a test of the March lows.
