Investors pulled money from Bill Gross ’s new mutual fund in February for the first time since the star bond investor moved to his new home at Janus Capital Group.

The Janus Global Unconstrained Bond fund saw a net $18.5 million in withdrawals from investors last month, and its assets under management sank to $1.45 billion from about $1.5 billion at the end of January, according to data released Monday by fund research firm Morningstar.
