A occurrence where the three major averages mentioned above are diverging from each other. During top line divergence, there is some combination of either one of the three being positive (up) with the other two negative (down) or one negative and two being positive. This indicates a choppy session as there is relative strength in some indices which may be acting as a drag on the others and vice versa. When the moderator calls out top line divergence generally the market is stuck in a range.
