Episode 278: Juhani Linnainmaa: Financial Advisors, and the Cross-Section of Returns

If you dive deep into financial advisor fixed effects, you'll begin to understand that an advisor's own portfolio has a bigger impact on the portfolios of their clients than the characteristics of the clients themselves. To help us make sense of this and to further explain financial values and the cross-section of returns, we are joined by the influential and notorious Professor of Finance, Juhani Linnainmaa. Our conversation begins with a comprehensive analysis of financial values, including a comparison between the trading patterns of advisors and those of their clients, a disquisition of misguided beliefs, an examination of client characteristics, and the ins and outs of portfolio variation and customizations. Canada recently adopted regulations from the Mutual Fund Dealers Association (MFDA), and we discuss how this has affected the use of financial advice in the country before comparing the benefit of increased equity share to the cost of advice, what hiring a new advisor before a financial crisis may mean for clients, and the role of regulation in the industry. We end with the cross-section of returns by examining accounting-based anomalies pre-1963, how profitability and investment relate to data mining, why a financial firm would switch between growth and value, and finally, Professor Juhani Linnainmaa's definition of success.
