Friday night the Quantifinder identified the below study. I haven’t updated it in over a year so I thought it would be interesting to do so.

Results are much the same as they were a year ago. Low QQQQ volume in an uptrend has often signalled at least a short-term drying up of buying interest. Historically this has created negative expectations over the next several days and weeks.

Much of the net negative thrust has often been found in the 1st two days following the setup.
