HDSN COULD SELL AT THAT TIME AND MAKE MORE MONEY FOR THE SELLER. But waits until the end of the day and sells for lower than the open.
with due respect: most stocks, most of the time, behave the same way. Around the 10 am mark the stock price is normally, not counting the anomali of positive PRs, higher than the rest of the day (that is why I avoid buying any stock at the 10 am -12 pm mark) then by 2 pm to 4 pm is when the price will normalize (most of time will dip from its 10am higher) - which, imo, is the best time to buy.
Perhaps HDSN could not sell all of its shares at the 10 am - 11 am mark and had to continue selling at lower prices later on in the day.
If HDSN withholds selling at the 10am-12 pm mark, as you suggest (when the price is higher), but only sells 2pm - 4pm mark, what reason for it to do that? what would be its motive?
