PIMCO’s Bill Gross has doubled the weight of non-U.S. developed market bonds in the firm’s $250 billion Total Return Fund, the world’s largest mutual fund.

Total return’s holdings of Treasuries and other U.S. government-related debt were unchanged at the end of last month as Gross has spoken positively of buying Treasuries at the end front end of the yield curve, include three-, four- and five-year bonds, Susanne Walker reported for Bloomberg.

That is how things shape for the mutual fund, but ETF investors that have embraced the PIMCO Total Return ETF (NYSEArca: BOND) no doubt want to know if Gross is taking a similar tact with the smaller, but more nimble BOND.  With $3.9 billion in assets under management, BOND is the largest actively managed ETF.

BOND’s maximum sector guidelines are as follows: 10% to junk bonds, 30% to developed markets ex-U.S., 15% to emerging markets and 20% to currency, according to PIMCO.
