Index funds have become some of the most widely-followed assets on Wall Street of late, with record-breaking capital inflows. Recent research by Arun Rangarajan of Harvard University defines index investing as “investing in a predefined and publicly known list of stocks using a publicly disclosed and replicable strategy.” Today’s article looks at index funds that could be appropriate for income investors. Given the growth of the importance of index funds in portfolios, individuals understandably want to learn more about them. For instance, most retail investors know that if you hold an index fund intended to replicate the S&P 500 index, you have a clear benchmark: the total return on the S&P 500 index. So far in the year, the index is up about 7% and hit a record-high in early April. The SPDR S&P 500 ETF Trust (NYSEARCA:SPY), an exchange-traded fund (ETF) that tracks the returns of the index, is also up around 7% year-to-date (YTD).InvestorPlace - Stock Market News, Stock Advice & Trading Tips 7 Great Stocks to Buy Under $10 With that information, here’re our seven index funds for passive income-seekers: Financial Select Sector SPDR Fund (NYSEARCA:XLF) Invesco Dow Jones Industrial Average Dividend ETF (NYSEARCA:DJD) iShares Global Materials ETF (NYSEARCA:MXI) iShares Residential and Multisector Real Estate ETF (NYSEARCA:REZ) Schwab Emerging Markets Equity ETF (NYSEARCA:SCHE) Vanguard Consumer Staples Index Fund ETF (NYSEARCA:VDC) Vanguard Dividend Appreciation Index Fund ETF Shares (NYSEARCA:VIG) Investors looking to profit from the long-term growth of companies stateside could simply buy an index-tracker ETF like SPY.
