Demand for ETFs steadied at a healthy level this week as stocks continued their march into record territory. On net, $11.5 billion flowed into U.S.-listed ETFs during the week ending Thursday, Feb. 18, pushing year-to-date inflows up to $129.3 billion, ahead of the $98.3 billion seen at this same time a year ago.

The weekly inflows went primarily into U.S. and international equity ETFs, which picked up $4.7 billion and $6.1 billion in new money, respectively.

Fixed income products didn’t fare nearly as well—inflows were negligible—with investors turned off by a swift sell-off in Treasuries and investment-grade corporate bonds. The 10-year Treasury bond yield touched a one-year high above 1.36% during the week (bond prices and yields move inversely) amid rising economic growth and inflation expectations.

ARK Assets Keep Piling Up

In terms of individual ETFs, the low-cost index fund mainstays and a handful of hot ARK ETFs continued to dominate the flows charts.

The Vanguard S&P 500 ETF (VOO), the SPDR S&P 500 ETF Trust (SPY) and the Vanguard FTSE Emerging Markets ETF (VWO) took the top three positions on the weekly inflows list.

At the same time, the ARK Fintech Innovation ETF (ARKF), the ARK Innovation ETF (ARKK) and the ARK Next Generation Internet ETF (ARKW) each picked up between $522 million and $746 million in new cash.

ARK is currently the seventh-largest ETF issuer, with just under $60 billion in total assets under management.

Its high-flying suite of ETFs sold off modestly this week, but each of the company’s funds is up substantially on a year-to-date basis.

Fixed Income Outflows

While equity ETFs generally remained well-supported this week, fixed income ETFs faced pressure, prompting some investors to lighten up their exposure to the asset class.

Several bond, gold and utility ETFs (considered a bond proxy by some) registered steep outflows during the week.

The iShares iBoxx USD Investment Grade Corporate Bond ETF (LQD), the iShares 20+Year Treasury Bond ETF (TLT) and the Utilities Select Sector SPDR Fund (XLU) took the top three positions on the weekly outflows list, with redemptions ranging from $782 million to $1.91 billion.
