QLC seeks investment results that correspond generally to the price and yield performance (before fees and expenses) of the Northern Trust Quality Large Cap Index. Given the potential economic headwinds like inflation, ETF investors will want to shore up their portfolios with quality funds that can outpace the major indexes, like the FlexShares US Quality Large Cap Index Fund (QLC). With that in mind, QLC can be their fund — it's up close to 22% on the year versus the S&P 500 Value Index's 20% gain.
