DoubleLine Asset-Backed Securities ETF (DABS)

The DoubleLine Asset-Backed Securities ETF (ticker DABS) is an exchange-traded fund that holds a portfolio of asset-backed securities, collateralized loan obligations, and other structured credit instruments. It represents the DoubleLine Capital philosophy applied to a liquid, daily-tradable wrapper: seek higher yields in the credit markets by owning loans and securities backed by underlying pools of consumer and commercial debt, rather than chasing those yields through risky equity stakes or long-duration bonds.

DoubleLine’s founding and philosophy

DoubleLine Capital was founded in 2009 by Jeffrey Gundlach, a veteran credit analyst and bond-fund manager, at a moment when the asset-backed securities market had nearly collapsed. The 2008 financial crisis had exposed deep flaws in the origination and underwriting of mortgage-backed securities: loans had been issued without proper verification of borrowers’ ability to repay, and the securities built from pools of these loans had been mispriced because investors did not understand the risks. The crisis taught the market to be extremely skeptical of structured debt.

Gundlach’s insight was not that asset-backed securities were inherently sound — the bad ones had deserved to blow up — but that the post-crisis repricing had created genuine opportunities in the wreckage. Good-quality loans, properly documented and prudently securitized, could offer attractive yields once the panic subsided. DoubleLine built a business around that bet, focusing on careful credit analysis and selection rather than taking on leverage or chasing the highest yields at any cost.

Over the 2010s, the firm grew by managing that strategy in traditional mutual funds and separately managed accounts for institutions and individuals. Returns were respectable, though often modest relative to the broader equity market. The fixed-income world is less glamorous and often slower than equities, but it is also more stable. By the late 2010s and into the 2020s, DoubleLine had proved that disciplined credit selection in asset-backed securities could work as a scalable, institutional-grade business.

The shift to an ETF wrapper

DABS was launched as DoubleLine’s entry into the exchange-traded fund space, bringing the same strategy — careful selection of asset-backed securities and structured credit — into a daily-tradable, transparent wrapper. The move reflected a broader industry shift: as ETFs became the default vehicle for many investors, asset managers who had previously run only mutual funds or separate accounts started adapting their strategies into ETF form to reach broader audiences and reduce fund minimums.

The DABS prospectus outlines the fund’s mandate: invest in asset-backed securities (which include mortgage-backed securities, auto-loan securities, credit card receivables, equipment leases, and other structures), collateralized loan obligations (pools of corporate loans), and similar credit instruments, with an emphasis on finding opportunities where the yield compensates for the risk involved and the underlying collateral is of reasonable quality.

What DABS holds and how it generates yield

Asset-backed securities are created by originating institutions — banks, auto lenders, credit card companies, and consumer finance firms — that bundle together many loans or receivables and sell securities backed by the cash flows from those underlying pools. When a consumer makes a car payment or a credit card payment, some of that cash flows through to the security holder. When a borrower defaults, the security’s value can decline. The yield an investor receives depends both on the coupon rate set when the security was issued and on the path of actual losses within the underlying pool.

DABS’ portfolio typically holds a mix of seasoned securities from earlier originations (which have substantial payment history and known loss patterns) and more recently issued ones. The fund does not chase the highest-yielding securities indiscriminately; instead, the managers assess the quality of the underlying loans, the structure of the security (which tranches are senior and protected, which are junior and more exposed), and the market price relative to the fundamental credit quality. That discipline is meant to avoid the trap of buying something cheap because it is radioactive and deserves to be.

The fund’s duration — a measure of how much a bond’s price will swing if interest rates change — is typically kept short, in the range of three to five years. That means DABS is not sensitive to the same large swings in value that a long-duration Treasury bond or mortgage-backed security would experience if rates spike. The shorter duration also means the fund returns capital relatively quickly, which in a rising-rate environment can be beneficial because that capital can be reinvested at higher yields.

Risk and the broader credit cycle

DABS carries meaningful risks that investors should understand. The primary risk is credit risk: if a large wave of defaults occurs in the underlying pools of loans — for example, auto defaults spiking during a recession, or credit card delinquencies rising sharply — the securities can suffer significant losses. The subordinate tranches, which absorb losses first, can be wiped out entirely.

A second risk is liquidity. While asset-backed securities are traded in large volumes and are generally liquid compared to some fixed-income instruments, they are not as liquid as U.S. Treasury bonds or liquid corporate bonds. In a market stress event where many participants try to sell at once, bid-ask spreads can widen sharply and large sellers may face price pressure. DABS, as an ETF, can be redeemed by shareholders daily, which means the fund itself must hold or be able to obtain enough liquidity to honor redemptions. During extreme market dislocations, that can strain the fund.

A third risk is interest-rate sensitivity. Though DABS’ short duration reduces this compared to longer-duration bonds, the fund is not immune to rate moves. If the Federal Reserve raises rates sharply, existing bond prices fall, and DABS could decline in value. The short duration mitigates this somewhat, but it is not a hedge.

Finally, there is structural risk. The asset-backed securities market evolves, and loan origination standards change. A period of loose underwriting — where lenders lower their credit standards to grow volume — can lead to poor-quality collateral that will result in elevated defaults years later when the cycle turns. Investors in DABS are, in effect, betting that DoubleLine’s analysis team can identify good collateral and avoid the worst of the garbage being issued in the current environment. If they fail, or if the credit cycle turns sharply, the fund’s returns can disappoint.

Who DABS is for and how to evaluate it

DABS is most suitable for investors seeking higher income than a traditional broad bond fund offers, with a tolerance for credit risk and a willingness to accept that in a bad credit environment, losses are possible. It is typically used as a diversifier within a fixed-income allocation, not as a core bond holding.

Researching DABS starts with the prospectus and fact sheet, which detail the portfolio’s composition, the top holdings, and the sector breakdown. Investors should review the fund’s performance history in different rate and credit-cycle environments — how did it perform during the 2018 credit scare, the pandemic selloff in 2020, or the interest-rate shock of 2022? That history offers clues to how the fund might behave in future stress. Reading DoubleLine’s quarterly commentaries and reports can also illuminate the managers’ outlook on credit cycles and the specific opportunities they see at any given time. Finally, understanding the fundamentals of asset-backed securities themselves — what drives auto default rates, how credit card delinquencies vary with the unemployment rate — is essential context for evaluating whether DABS is a good fit for your portfolio and time horizon.
