oh, sorry, here's the definition of material news. I thought I knew what it mean, and I was right.
"News released by a company that might affect the value of its securities or influence investors' decisions."
But the point is that you need to halt if that material news is leaked. Taken from your post:
"Trading halts are issued based on the principle that all investors should have the same timely access to important company information."
All investors got the information in the same timely manner so no halt. And it did affect the value of the securities and influence the investors decisions so it was material.
As for a halt on gqc, they should have halted the stock before hole 90 NR, there was trading the day before the news, a pop in volume and share price. I just wish when I saw it happening I loaded up instead of sitting on what I had.
