Insider trade on Splunk acquisition?
I know this isn't what happened, but what if one day I'm waiting for the bus and I over hear a guy talking on their phone about an imminent acquisition?<p>1. Would that still fall under insider trading even if the information was accidentally heard, and even if I wasn't 100% sure of its accuracy?<p>2. If I had no clear connection to the company how would it be proven that I was trading on insider information? Surely it's not enough just to say the trade was statistically unlikely, or is it?
