"This week on our Masters in Business interview, we speak with University of Pennsylvania Wharton School professor Jeremy Siegel, sometimes referred to as the “Wizard of Wharton.”
Siegel also is a senior adviser to exchange-traded fund provider WisdomTree Investments, and he was an early advocate of fundamental index ETFs. Rather than assembling an index by its market capitalization, fundamental indexing uses other metrics such as earnings, dividend yield or book value. The goal is a passively managed fund that avoids getting overweighted in specific stocks and industries, something that happened when hot tech stocks soared during the dot-com era."
