Concerned about the impact of Britain's upcoming vote on European Union membership, investors pulled $11 billion out of the 10 largest European equity exchange-traded funds year-to-date through June 15, according to S&P Global Market Intelligence's ETF reports on Tuesday.
Two of the largest ETFs, based on assets under management, had inflows in 2016, while others from BlackRock, SSGA Funds Management, WisdomTree, and Vanguard had sharp outflows.
Vanguard FTSE Europe, the largest of the European-focused ETFs with $12.68 billion in assets, had the third-highest year-to-date outflows, $1.06 billion, according to S&P Global Market Intelligence. The Vanguard fund has a hefty 31.40 percent stake in United Kingdom domiciled securities, including HSBC Holdings and Royal Dutch Shell.
