The number is zero. Any more than that would be a serious scandal--can't imagine that would be legal. Market manipulation is a pretty serious crime ever since the days of Jay Gould.
I'm not so sure, remember when it was perfectly legal for members of Congress and their staff to use information gained through their jobs to make stock purchases? I mean this was just a few years ago....
I'm not saying that consumer reports did anything wrong, but insider trading or not, it happens. And places we would not expect. Who would've ever thought that members of Congress in their staff would be allowed to do insider trading? Until someone pointed out that it was illegal some years back, it never crossed my mind. I assumed it was illegal
