(New York)

ETFs are a product that has been growing at breakneck speed. AUM in the product is approaching $4 tn, which is astonishing given that it has really only taken a decade to get there, but still quite a bit smaller than the $16 tn in mutual funds. Experts say that the ETF market is going to increasingly resemble the mutual fund market as offerings diversify into smart beta, thematic ETFs, customizable ETFs, and fixed income. The last area—fixed income—is where creative indexing makes the most sense, as doing so can account for the common weighting issues that are much riskier in bonds than in equities (you don’t want your largest holding to be the issuer with the most debt).

FINSUM: The logic for fixed income ETFs is very strong, especially given how illiquid and restrictive buying bonds directly is. However, smart beta and other active ETFs (which are more expensive) don’t really have a big leg up on experienced mutual funds.
