"Before this data, nobody knew the stock market's total return. People had opinions, but without data almost everyone was just guessing. It turned out the market did better than people imagined. In fact, marketwide performance beat many famous stock pickers. The investment world had been doing it all wrong."
"Rather than adopting the conventional wisdom of his industry, Beane forges a new path based on cutting-edge statistical analysis. Real data, instead of gut instinct. The sport had been doing it all wrong. This is what it was like at the University of Chicago in the 1960s when the Center for Research in Security Prices first assembled that reliable stock market data dating back to 1926."
The University of Chicago's Center for Research in Security Prices assembled reliable stock market data dating back to 1926, revolutionizing financial analysis similar to how Billy Beane used statistics in baseball. Before this data existed, investors relied on opinions and guesses rather than facts about actual market returns. The research revealed that overall market performance exceeded what most people imagined and outperformed many famous stock pickers. This discovery demonstrated that the investment industry had been operating incorrectly, relying on conventional wisdom instead of empirical evidence. The centennial of this research marks a significant milestone in understanding market behavior and validates the importance of data-driven decision-making over intuition in investing.
