Hi Tootip
Here are the day’s trades in half hour bites per link http://www.nasdaq.com/symbol/ssh/real-time
Starting from 9:30 to 9:59 through to 15:30 to 16:00 –
3,200; 1,473; 3,989; 500; 12,206; 9,871; 24,889; 300; 2,500; 1,100; 100; 100; 7,350 sums to 67,578.
But summary for day says 129,269 ( http://www.nasdaq.com/symbol/ssh ) which is 61,691 above the sum of the half hourly reports of real time sales.
Are you able to throw any light on this? Is the difference of 61,691 private placements, stock options exercised, or what?
Trust you or other readers might be able to clarify.
