State Street Global Advisors launched two new ETFs on Thursday that set out to help navigate ongoing bond market uncertainty.

SPDR DoubleLine Short Duration Total Return Tactical ETF (BATS: STOT) and SPDR DoubleLine Emerging Markets Fixed Income ETF (BATS: EMTL) began trading today on the Bats Global Markets.

Developed by SSGA and DoubleLine Capital, the new ETFs build on the success of the SPDR DoubleLine Total Return Tactical ETF (TOTL), the fastest-growing ETF launched in 2015.

STOT seeks to maximize current income with a dollar- weighted average effective duration between one and three years. STOT is managed by Jeffrey Gundlach, chief executive officer and chief investment officer of DoubleLine Capital, Philip Barach, DoubleLine president and Jeffrey Sherman.

The fund seeks to maximize total return over a full market cycle through active sector and security selection across a broad range of fixed income securities that could include, among others, securities issued or guaranteed by the US government, foreign and domestic corporate bonds, emerging market bonds and agency and non-agency mortgage backed securities. STOT has a gross expense ratio of 0.50 percent and a net expense ratio of 0.45 percent.

Meanwhile, EMTL seeks to offer actively managed exposure to fixed income instruments from emerging market sovereign and corporate issuers. The SPDR DoubleLine Emerging Markets Fixed Income ETF has a gross expense ratio of 0.75 percent and a net ratio of 0.65 percent.

In February 2015, State Street Global Advisors and DoubleLine Capital launched the SPDR DoubleLine Total Return Tactical ETF (TOTL), which offered access to DoubleLine’s active investment management. Attracting over $1.7 billion during its first ten months, TOTL was the fastest-growing ETF launched in all of 2015. Net assets under management in the SPDR DoubleLine Total Return Tactical ETF totaled over $2.2 billion as of March 31, 2016.

EMTL seeks to provide high total return from current income and capital appreciation. EMTL is managed by Luz Padilla, director of DoubleLine’s International Markets Fixed Income Team, Mark Christensen and Su Fei Koo. The fund seeks to maintain a weighted average effective duration between two and eight years through active security selection that combines bottom-up research with sovereign macro overlays.

James Ross, executive vice president and global head of SPDR Exchange Traded Funds at SSGA, said its clients have been asking us for solutions to help them navigate ongoing bond market uncertainty,

He added they were pleased to be expanding their relationship with DoubleLine to seek to help clients address this challenge.

“These additions to the SPDR line-up provide investors with new actively managed fixed income ETFs that may be able to help strengthen and complement core bond holdings,” Ross said.
