I am guessing you aren’t a big crypto investor :). You are making an assumption that the other investors are all rational and use the same criteria when buying stocks. That is becoming less and less true every day.

Well if that's the case we can all go home, welcome our quant finance overlords with grace and hope they are magnanimous towards us mere mortals.

Reading other people's minds is not yet possible :( , for everything else there's AQR, RenTech and D.E. Shaw.

My point is that some stocks people are buying with their hearts and not as much with their brains. They believe in the future and they buy no matter what the price. Revenue multiples are not considered. Spacex will almost certainly be one of these stocks when it goes public.

that is the same as my point. You have to be able to read the emotions of all the other market participants

Furthermore, $650 billion is spent on advertising each year and growing. That's a huge TAM for ad-tech companies like Google and Facebook.

What is the global spend on space launches annually? $5 billion maybe? And not growing very quickly, if at all. And most of that market is inaccessible because many of the biggest space agencies prefer to keep things in-house, even if it means a worse product at a higher cost.
