I made a number of bets on the tech industry early on in my career (2005-08): that the Web and Javascript would become increasingly more important, that Python would be a major language both for web development and for scientific computing, that Google and other new tech companies would continue growing until they were bigger than we could imagine, that startups would become a more respectable way of spending your career. I would happily crow about them to anyone that would listen, while also arranging my professional life to benefit from them. They happened. Did I cause the ascendancy of Javascript, or Python, or Google, or startups? Of course not. I called it, and then lots of other people, as events progressed, independently made the same call and jumped on the bandwagon.
So it is with Dalio (and Buffett, and other thought leaders in the financial industry). It's unlikely that their words are moving markets, particularly since their bets are often contrarian and unremarkable at the time they start publicly stating them, and financial markets often take years to catch up. Rather, they spot the trend, understand the implications, and then position themselves to benefit when everyone else spots the trend and understands the implications.
