Investors added about $2.5 million to Bill Gross’s Janus Global Unconstrained Bond Fund in March, the first net inflows since October to the $1.3 billion mutual fund, according to data compiled by Bloomberg.

The fund, which invests in fixed-income securities and derivatives, is up 1.9 percent this year through Thursday. It is coming off its best quarter since Gross took over management in October 2014 after his acrimonious departure from Pacific Investment Management Co.

He is outperforming 90 percent of his Bloomberg unconstrained bond fund peers and ranks in the top 15 percent of Morningstar Inc.’s nontraditional bond funds this year. Since Gross took over management on Oct. 6, 2014, the fund has had a total return of almost 1 percent.

Investors withdrew about $2.3 million from Gross’s fund in February, $14.8 million in January, $57 million in December and $74 million in November after adding $5.9 million in October. Gross manages the fund with Kumar Palghat.

Redemption estimates for the Janus fund are based on the change in assets over the month that isn’t accounted for by performance or reinvested dividends. The number may vary from actual figures and from estimates compiled by other data providers.

Janus spokeswoman Erin Passan declined to comment on the fund’s flows.
