As far as the INSIDER SALES AND AQUISITIONS are concerned I don't think that it would be out of line that a required news release, "immediately" after the activity on the same day ,no matter what time of the day of the insider activity was made MANDATORY, in order that a company stay in good standing with MARKET GOVERNING AUTHORITYS , wether it be the US orCANADA, even to the extent of HALTING THE STOCK BEFORE THE TRADE (instead of announcing a trade a WEEK later)
Now that would be an excellent idea,,,but that won't happen or then the big $$$ people would be peons like us,,,lol
