Important insider information is seldom kept secret from family, friends, and close associates But it's seldom revealed to strangers, as insiders know they expose themself to job loss and jail.

So if 10 insiders are originally in on a big secret, some will be telling the story to family, friends, and associates. And then they each tell others, and so on like a chain letter.

The point is, if one gets insider info from a stranger on the phone and its true, the news is most likely already reflected in the SP - because of the leaks. But maybe you’ll be the lucky stranger who is in on the 1st round of the chain. That's probably as likely as winning the lottery - but it happens.
