SPY Retakes Lead After Briefly Trailing VOO in AUM

The Vanguard 500 ETF (VOO) briefly overtook the SPDR S&P 500 ETF (SPY) last week as the world’s largest ETF by assets under management. This marked a significant milestone for Vanguard, the ETF industry, and was a sign of growing retail adoption.

“This was a tremendous milestone for [VOO] to initially pass [SPY], and I think it will pass again,” Rosenbluth said. “The Vanguard ETF tends to gather assets from buy and hold investors that are more strategic, retail, financial advisors. Whereas SPY, based on our understanding, is used by institutional investors. Market volatility, like we've had in the past week, is actually a good thing for people turning to SPY because of its liquidity and a tactical approach.”
