After Vanguard’s decision to swap out a bundle of exchange traded fund underlying MSCI indices for FTSE and CRSP benchmarks in an attempt to cut costs, the industry has put the spotlight on indexing. Nevertheless, when it comes down to it, it’s the investor’s opinion that really matters.

Dodd Kittsley, iShares head of global exchange-traded product market trends research, previously pointed out that the S&P-, MSCI- and Russell-benchmarked ETFs account for 85% of U.S. equity assets, and MSCI also made up a 60% market share in emerging market ETF assets and 51% in global assets.

“Clearly, when it comes to choosing an index to track, many investors favor certain index providers for specific exposure types,” Kittsley said.

“The thing we all want to keep at the back of our minds is we don’t want anything to happen in the industry that will stop the innovation that has been happening,” Rick Redding, executive director of the IIA and former CME Group executive, said in the article.
