Original Summary

Why should investors care about social media sentiment? “The key to success is being where other investors will be, several months before they get there. So ask yourself whether the story about your stock is one that is likely to catch the fancy of the crowd. Can the story generate contagious dreams? Is it a story on which investors can build castles in the air—but castles in the air that really rest on a firm foundation?” — Burton Malkiel In Burton Malkiel's A Random Walk Down Wall Street. He describes two theories of asset valuation, the Firm-Foundation Theory and the Castle-in-the-Air Theory. You're probably familiar with the Firm-Foundation Theory , it claims that every investment has a true intrinsic value based on future cash flows, earnings, and dividends. The Castle-in-the-Air theory is all about crowd psychology. It believes investments have value because other people believe they have value. It describes cryptocurrencies, meme stocks and sets the price for Chanel bags. It's hype, newsprint, and stock tips from your hair dresser. It was always possible to measure the Firm-Foundation , but we've only recently been able to measure the Castle-in-the-Air with the ubiquity of social media. I built rumor.io to join the Firm-Foundation AND the Castle-in-the-Air . Choose investments with a firm foundation that also have the attention of the crowd. Try to understand what appeals to investors. It doesn't mean always following the hype, it's about anticipating where the hype is going next.
