FYI: While index investing has been gaining traction, exchange-traded funds have been taking market
share away from index mutual funds during the past decade. This could be due to ETFs’ intraday
tradability and broad accessibility. Many also attribute this trend to ETFs’ perceived cost and tax
advantages over index mutual funds. ETFs do not incur some of the administrative costs that their
index mutual fund counterparts face, but they are not always cheaper.
