The market’s recent rebound has emboldened ETF investors, who are pumping money into equity funds with energy and real estate leading inflows among sectors.

Investors added $9.4 billion to U.S. stock ETFs in June following two months of net outflows, investment research firm Morningstar said Tuesday.

The company notes that in the top-heavy ETF business, the largest managers continue to get bigger.

For example, State Street Global Advisors collected inflows of about $9 billion last month to lead all ETF providers. It is the second-largest ETF manager with $291 billion in assets, according to Morningstar.

BlackRock’s iShares is the largest with $482 billion while Vanguard follows State Street with $209 billion.
