If that's the case, it seems like the executives at Equifax who were dumping stock after they learned of the breach (but before it was reported) were jumping the gun. They should have just held on to it!
"Three senior executives including the company’s chief financial officer sold $1.8 million in shares three days after the company learned on July 29 hackers had breached personal data for up to 143 million Americans."
