There are opportunities to spot mispriced securities and to capitalise on the present volatility. Global events including disinflationary pressures abroad, and a domestic Fed poised to move away from its Zero Interest Rate Policy, makes this an opportune time to exploit relative mispricing in prepayment- sensitive securities. Surveying the landscape of fixed-income alternatives, investors have extended duration or have taken on undue credit risk in this low interest rate environment to achieve returns. As other markets being to appear closes to fully priced, prepayment arbitrage strategies will likely exhibit less volatility while producing a stable source of return. The in-depth modelling of homeowner behavior that informs prepayment arbitrage strategies enables them to outperform and capitalise on uncertainty.
THE VALUE OF A LIQUID MARKET-NEUTRAL FIXED-INCOME STRATEGY Since 2008, investors in hedge funds have demanded better liquidity terms and now, more than ever, avoiding illiquidity is a critical concern. With liquidity risk mounting due to a confluence of factors, it is paramount for managers to focus on strategies that can support shorter-term cash needs while providing a stable and attractive risk-adjusted return. An alternative fixed-income strategy that includes Agency relative value can achieve these goals through the tactical use of basis trades, dollar rolls, coupon swaps, term swaps and inter-agency swaps. We discuss the liquidity profile of these securities that form the basis of our Agency relative value trading strategy.
Strong Liquidity in the Agency Pass-Through Market Agency pass-throughs are one of the most liquid fixed-income instruments after U.S. Treasuries. Commonly referred to as “TBA” (To Be Announced) securities, these securities trade as a forward market for Agency bonds, which are securities that are backed by the U.S. Government’s credit guarantee through Fannie Mae, Freddie Mac or Ginnie Mae. TBAs account for more than 90% of Agency pass-through trading, and there are scores of dealers active in the market. Issuance standards at both the loan and security levels give Agency pass-throughs a high degree of homogeneity, which helps to make the otherwise heterogeneous underlying loans extremely liquid. The average notional trading volume for TBAs is 165 billion USD per day, with bid-ask spreads ranging from 1/32 of a percentage in normal periods to 3/32 in extreme environments. The depth of the TBA market and low bid ask demonstrate just how liquid this market is. It is worth noting this market remained robust during the financial crisis, while structured credit and high yield corporate credit issuance declined to untenable levels. The outstanding stock of Agency bonds during
this period of acute duress actually increased from 3.99 trillion USD in 2007 to 5.27 trillion USD at the end of 2009. Agency pass-throughs clearly stand firm as one of the strongest avenues of liquidity across all fixed-income securities.
Relative Value Trading in the Agency Pass- Through Market TBAs are not only liquid, but also offer frequent alpha opportunities when traded tactically. Relative value (RV) trading strategies in Agency pass-throughs often register significant dislocations which can be capitalised on via statistical arbitrage and mean reversion trading. In the case of a basis trade, TBAs can be hedged using U.S. Treasuries, creating a duration-neutral position with an attractive risk- return profile.
Potential threats facing investors include credit and “liquidity” risk. A fixed-income arbitrage strategy that includes Agency relative value is well positioned to meet rising challenges that investors face from increased liquidity concerns while providing alpha opportunities and a low correlation to traditional assets. In the case of the Tradex Relative Value Fund, we believe this ultra-liquid component of our multi- strategy approach will keep our overall liquidity very advantageous in the current environment.
“Multi strategy fixed income portfolios are well equipped to generate alpha in times of increased volatility.”
We give a few examples of RV strategies that may be available in this space. Agency basis trades typically exploit moments of detachment in the pricing of Agency securities relative to U.S. Treasuries or Interest Rate Swaps by either going long or short the basis. Trades in the dollar roll market profit from moves in the “drop”, which is the difference in price of TBA securities between settlement months. Coupon swaps can be used to exploit mispricing between Agency securities with different coupons, as technical factors in the market and origination channels can distort relationships across the coupon stack. Term swaps target valuation differentials between securities issued by the same Agency with different maturity terms. Similarly, inter-agency swaps exploit dislocations in the prices of bonds of the same coupon and term, but issued by different Agencies. There are a variety of relative value strategies that can be utilised in the TBA market, and these tactical trades can be effective largely due to the ultra-liquid nature of this market.
WHAT'S NEXT IN CREDIT Following the 2008-2009 financial crisis, credit- sensitive securities experienced unprecedented spread widening as investors lost confidence not only in homeowners’ ability to repay mortgages, but in housing finance altogether. Being short of credit-sensitive securities during this period and subsequently purchasing over-penalised securities provided exemplary opportunities to generate outsized returns. Having navigated the Big Short and the Big Recovery, the Tradex team has adopted an opportunistic sub-strategy that is capable of taking advantage of such outsized market moves. While the Big Recovery has all but ran its course, there are a few sectors worth watching in the current credit cycle.
GSE Credit Risk Transfer (CRT) Government-sponsored enterprises (GSEs), like Fannie Mae, Ginnie Mae and Freddie Mac, issue credit risk transfer (CRT) bonds to transfer a portion of credit risk on mortgages they guarantee to private investors. Such a transfer has the added benefit of diversifying credit risk among several investors, as opposed to concentrating it in the hands of GSEs. Spread widening and risk-off sentiment has pushed CRT spreads wider and the credit curve steeper. At the same time, the housing market continues to recover and the current low interest rate environment (i.e. low refinancing incentive for borrowers) remains supportive of fundamentals. While there is value across the CRT space as a whole, we see the best risk/reward in the last cash flow (LCF) tranches. These classes have benefitted from strong housing fundamentals, resulting in homeowner balance sheet deleveraging due to strong prepayments and low defaults. With spreads 450 to 500 over swaps and spread durations of 7 to 8 years, we see this sector as having the potential to return 7 to 10 percent over the next year with strong carry and modest roll-down/spread tightening. Issuance of CRT remains strong and by all accounts, the market is here to stay.
Non-QM The qualified mortgage (QM) rules opened the door for private investors to originate non-qualified mortgages, and these loans are now becoming a factor in the RMBS market. Lenders are currently seeking access to the securitisation market, after
