This exact scenario happened to me. I was flying United business class SFO to EWR and the guy next to me was writing a Powerpoint slide in 9000-point bold type "BUY XYZ CORP FOR 880 MILLION" and when I got to work a few hours later our counsel advised me that it was not at all improper to trade on that information, which we did.
Well, I’ve figured out how I’m spending my spring break- buy a ton of cheap stock in some random startup, dress head-to-toe in Microsoft swag, and then spend a few days hanging out in various SFO lounges working on fake PowerPoints declaring intent to buy the startup
Seems good. But I also feel like if you're the kind of person who can command the disposition of a billion dollars, just stop writing slides. Stand up in front of the board and say what you came to say and then sit back down.
