FYI: Assets in global exchange-traded funds (ETFs) rose from about $70 billion in 2000 to more than $4.5 trillion by the end of 2017. This dramatic growth has raised a variety of concerns about the possible detrimental impacts of these flows on underlying securities—with many arguing that substantial flows into ETFs and other index vehicles have increased comovements and volatility in returns of constituent securities.
