Founder, chairman, and CEO of Fisher Investments, a multibillion-dollar money management firm headquartered in Woodside, Fisher is obviously an expert on finances. So it makes sense that he has been a columnist for Forbes for nearing three decades. He’s also the author of six books, including the New York Times bestseller How To Smell a Rat. Fisher has written dozens of research papers in the field of behavioral finance, and his theoretical work identifying and testing price-to-sales ratios made groundbreaking strides in defining and using PSRs as a financial forecasting tool.
