The 20 largest fund flows so far this year total a bit more than $94 billion. Eighteen of the funds are passive and carry especially low expense ratios (a median of 8 basis points).

By company, iShares was the biggest winner in YTD flows, with 11 of the top 20. As for type of fund, it ran the gamut: S&P 500, small cap, emerging markets and fixed income.

Consider the overall total for another moment. If $94 billion were a company’s annual revenue, it would rank #23 on the newly released Fortune 500 – more than Citigroup, Wells Fargo or Bank of America.
