Others have replied to this, and I agree that it sounds like a car salesman's pitch. But a CEO who doesn't tell you to buy lots of his company stock is not doing his job. While HB was talking, almost 200K shares traded in the PM; that is impressive!
And just to be complete, a CEO that promotes his stock when he KNOWS (or is in a position that he should know) of materially adverse conditions, is putting himself in serious trouble.
HB put it all out there, and did a tremendous job.
