Such ETFs include the Vanguard S&P 500 ETF (VOO) which brought in $46 billion in flows, and the Vanguard Value ETF (VTV), which, even in a less-than-stellar year of performance, still brought in $15 billion in flows. Nadig explains that having money in these more predictable, large, diversified funds that invest broadly is a great thing. Looking ahead for TIPS after a huge year, Nadig actually believes that a better play in 2022 will be commodities when investing for systemic, longer-term inflation.
