Numbers aren’t everything and the speaker makes some good points. That being said, every bubble in history has been built around a story that excited the marketplace.
I am of the opinion that good companies don’t need to be propped up with fantastical stories. Which is not meant to demean the prose associated with a company. But that prose needs to be closer to a documentary than a tall tale.
Your investment horizon also makes a difference. If you are investing for a few days to a few weeks, story can work. If you you are investing for multiple years story is more likely to get you into trouble than the numbers.
