Leading the way in net inflows were diversified emerging markets ETFs ($4.6 billion in inflows) and high yield ETFs ($2 billion).
Through the first 10 months of 2011, ETFs (including ETNs) saw net inflows of $94 billion, a pace that could produce the fifth straight year of $100 billion or more in inflows to ETFs, SI said.
At the end of October 2011, U.S. ETF assets stood at $1.08 trillion, up from $970 billion at the end of September.
