pkp, according to trade volume for December HDSN had 21.5 M shares whereas NITE, ETMM and AUTO had combined 85.5 M shares. So with so few shares compared to the top three MMs why is it always HDSN which moves in mid afternoon to take the daily pps down and rarely the top three MMs? We do not complain about the top three because we do not experience them seemingly walking down the pps by assuming the low ask as does HDSN. We should experience this walk down as being more related to the other three MMs taking it down given they combined have four times more volume.
