I think this is why regulators are concerned about the steep drop in "startups" going public. You have these huge companies with enormous valuations, and they arent subject to the disclosure and reporting requirements that regulators have designed for public companies...
The most ridiculous recent example was Morgan Stanley marketing Uber to high net worth individuals. [0] Potential investors were not even allowed to see the financials! You just had to take Morgan Stanley's word for it that the valuation was "reasonable".

The effects of these consolidated investment cycles result in bubbles. The more stored trust involved, and the more systems put in place to bring more stored trust to bear on an idea, market, company, etc., the more disruption there will be on the changes in the cycles. Cycles are a thing with technology, probably due to the discovery phases of market bubbles. All theory, of course. I'd like to see it put to analysis though.
Better?
