the QQQ needs to see topping confirmation price action before SPY heads back down in earnest
* bulls need the $NDX & QQQ to hug the daily 200,2 upper Bollinger Band for a period of consecutive weeks
* the % change for QQQ and $NDX starts with the end of 2014, and the current QQQ high of +78.12% change is marked with a green horizontal line
* Note - the ratio of QQQ to SPY price action sits at a new multi-year high ... mutual funds and ETF's have investing $'s concentrated in an increasingly smaller number of stocks
