Well before the market opened for trading today, I stated that: it is clear that today’s large gap in the $NDX/QQQ will be largely due solely to one stock, AAPL (Apple).  As appearances can be deceptive at times, the charts below help to support the case that the impressive gain of nearly 1% in the $NDX/QQQ today was indeed almost exclusively due to a single stock, that of the largest weighted component of this market leading index. Although I often like to say that one day does not make a trend, I believe that the market internals warrant close monitoring at this time as today had the feel of large but stealthy institutional selling that began immediately following the large opening gap in the $NDX today. The remainder of my thoughts are summarized in the annotations on the charts below.
