The flagship fund of Jeffrey Gundlach's DoubleLine registered outflows in December amounting to $2.08 billion, Reuters reported. Citing data from Morningstar on Wednesday, January 1, the report said this marked the seventh straight month that investors had taken their money out from the fund. Morningstar gives independent investment research to investors around the world.

Reuters reported that a bond market selloff and bond fund outflows were triggered after Federal Reserve Chairman Ben Bernanke told Congress in May that the agency could start tapering its monthly bond purchases in 2013 if the economy in the US would be strong enough.

Morningstar said the most recent outflow from Los Angeles-based DoubleLine Total Return Bond Fund has brought total outflows from the fund in 2013 to an estimated $6 billion. However, the outflows in December were the largest in three months, data from the research firm showed. It was even more than double the $811 million worth of withdrawals made by investors in November last year, research showed. The first ever monthly outflow was posted by DoubleLine in June last year when investors took out $1.2 billion.

DoubleLine Chief Executive Officer and Chief Investment Officer Jeffrey Gundlach runs the $31 billion fund, which posted a slight 0.02% increase last year, outperforming 87% of its rivals, based on data from Morningstar.

Information from the website of DoubleLine revealed that as of September 30, 2013, it had more than $52 billion in assets under management, the report said. The website also showed that DoubleLine's mission is to give their clients better risk-adjusted returns. The company also invest substantial resources in staff and systems in order to match resources with the demands of managing market risk and to follow the guidelines of clients. The DoubleLine website also said that company-wide stability is reinforced by employee ownership, making the investment team and principals more directly accountable to the client.
