(Bloomberg) -- Investors pulled $33.2 million from Jeffrey Gundlach's DoubleLine Total Return Bond Fund in October, the first outflow since January 2014.

DoubleLine's open-end mutual funds collectively posted a net inflow of $455.3 million last month and $12.3 billion this year, Los Angeles-based DoubleLine Capital said Tuesday in a statement.

The $61.6 billion Total Return has been one of the industry's fastest growers, and a year ago it reached the $50 billion milestone in record time for an actively run stock or bond mutual fund.

This year through October the fund gained 3.7%, trailing the benchmark Bloomberg Barclays U.S. Aggregate index, which rose 5%. Total Return, which invests mostly in mortgage-backed securities, has outperformed 71% of its Bloomberg peers in 2016, 90% over the last three years and 92% over five years.

Gundlach's biggest fund has received an inflow of $8.3 billion year-to-date, according to DoubleLine.

The firm also said the $7.7 billion DoubleLine Core Fixed Income Fund took in $166.5 million during October, bringing year-to-date net deposits to $2.1 billion. The $1.4 billion DoubleLine Shiller Enhanced CAPE Fund, which combines fixed-income investments with derivatives that track stock sectors, attracted a net $77.3 million in October and $672 million this year.
