Don't believe something happened. So there was a seller with a million or more shares that wanted out today. With a stock that has an avg. volume of appox. 1.2 million shares traded a day, a drop would be expected with a big seller. It will take two to three quarters of sales growth for GRNH to prove itself. I expect big sales in the 4th quarter this year.GRNH may recover most of the downside by the end of the day.If not today,tomorrow. IMO.
