with an investor conference call on the morning of Thursday, July 27.
Any public company I've worked at has had a trading window that opened a day or two after an earnings report came out, with most people who want to trade trading early in that window. Admittedly I've never been an executive and I don't know how the rules differ for execs, but the dates when these trades took place are when I would expect Equifax employees to execute options and sell stock.
It also strikes me as possible that information about a security breach discovered on the weekend might not make its way up the company hierarchy for a few days, and that execs might not have been aware of it when they traded.
I do think this should be investigated by the SEC, but I'm a little disappointed at the rush-to-judgement in this thread.
