Strategy Spotlight Getting More From Your LDI Portfolio Our approach to investing in long duration and long credit portfolios has delivered meaningful alpha over most market cycles.
In July, we rebutted the narrative that liability-driven investing (LDI) portfolios are best managed with less discretion and lower alpha targets. We believe the opposite: When risk, return and costs are properly defined, active management of LDI assets should handily beat further allocations to return-seeking assets on the efficiency scale, and thus a higher active risk LDI approach potentially leads to better risk-adjusted outcomes. (See "When More Is Less: Dialing Up Active Management in LDI Portfolios May Reduce Risk.") But how best to implement this strategy in LDI? In the following Q&A, portfolio managers Mike Cudzil and Mohit Mittal, and the leader of pension solutions in the Americas, Rene Martel, outline PIMCO's investment approach and its potential for generating alpha. Q: How much alpha should investors reasonably assume can be consistently achieved in long duration and long credit portfolios? A: In the U.S., most LDI portfolios include a meaningful amount of credit exposure, with some even benchmarked 100% against long credit indexes. This opens up a wide range of opportunities to outperform the index. Our approach, which emphasizes diversified sources of alpha and balances bottom-up and top-down considerations, has historically and consistently delivered more than 100 basis points of alpha over most full market cycles (see Figure 1). Q: Can you explain how you apply PIMCO’s investment process to long duration portfolios? A: Essentially, it's no different than our approach to managing fixed income portfolios in general. It begins with the principle of diversification. We believe that no single risk should dominate returns. We seek to add value through a disciplined approach that combines credit selection with top-down macroeconomic forecasts and sector rotation. By diversifying strategies and relying on multiple sources of value, we seek to generate a solid track record with a high degree of consistency. For decades, our investment process has been grounded in our Secular and Cyclical Forums, which bring together PIMCO investment professionals from around the world on an annual and quarterly basis, respectively. Our annual Secular Forum, which features several days of rigorous debate, including input from outside experts, distills a broad outlook for global macroeconomics and markets over the coming three to five years. These top-down insights help determine how portfolios will be positioned in relation to their benchmarks and broad market factors, including duration and sector exposures such as credit, mortgages and emerging markets. We fine-tune these views at thrice-annual Cyclical Forums, which incorporate current economic and financial developments to determine our six- to 12-month views. Finally, PIMCO’s Investment Committee meets most days to further refine the firm’s model portfolio with real-time information. Importantly, implementation and specific positioning are informed by bottom-up perspectives. These reflect input from teams of specialists in all areas of the fixed income markets. In credit, for example, more than 50 dedicated analysts conduct conduct thorough independent research to select individual securities. Notably, we do not rely on credit rating agencies. Historically, about 60% of the 11,000-plus securities PIMCO evaluates independently have had ratings that differed from those of the agencies. Additional bottom-up insights into trading and security selection flow from traders, analysts and portfolio managers across the full range of fixed income securities, including Treasuries, agencies, mortgages and emerging markets. All told, PIMCO has more than 100 global credit investment professionals in nine offices around the world. When it comes to LDI, our portfolio construction approach considers the unique nature of long duration portfolios. We analyze key rate-duration buckets, idiosyncratic credit risks related to longer maturities, and the dynamic nature of LDI benchmarks. For example, portfolio liquidity and positioning reflect the fact that certain LDI portfolio benchmarks are adjusted frequently to maintain their fit with liabilities. In addition, the credit research and issue-selection process takes account of the significant difference in average maturities of securities in LDI portfolios relative to broader bond mandates. As such, our tolerance for downgrade events and spread-widening may, at times, be lower in long duration portfolios. Finally, given the domestic focus of LDI strategies - driven by domestic discount rate methodologies - we tend to use non-U.S. exposures and currency management to a lesser extent than in other lines of business. These processes have helped us to achieve the same excess return generation consistency in long duration portfolios as PIMCO seeks across a wide range of strategies and mandates (see Figure 2). Q: Long-term bonds represent a small subset of the fixed income universe. What challenges does this present to alpha generation? A: In the U.S., the long duration universe, as defined by investment grade securities (both government and credit bonds) with maturities longer than 10 years, represents approximately 15% of the broad investment grade bond market. This presents some challenges: For example, at times liquidity may be lower than most market sectors, requiring investors to work harder and smarter to achieve proper issuer and sector diversification. Transaction costs also are likely to be higher. In addition, we always keep in mind that in long credit markets we are lending clients' money for fairly long periods of time. These factors - liquidity, transaction costs and long lending periods - magnify the potential negative impact of a mistake in credit assessment or a misjudgment in the evolution of a credit rating. They explain why thorough credit research is especially important in LDI. Importantly, however, these challenges represent alpha opportunities for skilled managers. Having sizeable and skilled credit research resources, we believe we can harness the premiums that potentially exist because of the challenges noted above. In that regard, we view our size as a significant advantage: It allows us to maintain a sizable amount of analyst, portfolio management and technological resources to quickly respond to market opportunities. It also helps facilitate partnerships with companies we view favorably, creating opportunities for long-term financing. Our market footprint can also help us influence debt covenants to the potential benefit of clients. Given all this, we think our ability to add alpha in LDI portfolios is very similar to the potential for adding alpha in traditional total return fixed income portfolios. In addition to alpha potential, we have developed innovative investment structures that seek to help our clients overcome challenges in long credit and long duration markets. Our long credit sector fund is a good example. This vehicle, used exclusively within our institutional separate accounts, pools long credit purchases of numerous investors into a private, commingled vehicle that creates opportunities and advantages, including the potential to: Get almost immediate exposure to the long credit market – rather than the several weeks often required to put cash to work in that segment of the market Achieve a high degree of diversification as investors access a portfolio that has incorporated new issues over several years (rather than just a few weeks of new-issue exposure) Reduce transaction costs thanks to heightened liquidity and the size of the commingled vehicle in relation to the size of any of its underlying investors Improve the liquidity profile of a long credit allocation, as any liquidity requirement (be it for benefit payments, rebalancing or other reasons) is generally quite small in relation to the size of the pooled vehicle Q: Let's talk about current market conditions. Corporate spreads are relatively tight and the Federal Reserve is gradually normalizing rates. Is this environment still conducive to achieving excess returns in line with PIMCO's recent historical experience? A: Actually, we believe today's environment has the potential to create even greater opportunities than those of the past several years. In recent years, central bank intervention has helped to suppress volatility in markets (although various subsectors have continued to see bouts of volatility, such as energy in Q1 2016/Q2 2017, autos in Q1 2017 and retail in Q2 2017). As a general rule, increased volatility should lead to increased alpha-generating potential (within reason). Our base case is that the Fed begins to shrink its balance sheet after the September meeting. If so, we see scope for volatility to increase, creating even more potential to add value in LDI portfolios. Our approach to credit investing seeks to identify companies and sectors that will outperform – or underperform – the broad market. Historically, security and sector selection has contributed about two-thirds of our alpha in credit strategies. Even though the aggregate level of credit spreads has tightened, we believe many sector-specific changes will be important drivers of excess return potential over the next 2-3 years. Consider, for example, that old media is being replaced by new media, Amazon is disintermediating brick-and-mortar retail stores, technology is revolutionizing energy and autos, and merger-and-acquisition cycles are shaking up numerous other sectors. Similarly, individual companies with strong assets and hard-to-penetrate markets may be well-insulated from future growth slowdowns. With our extensive resources and decades of experience as one of the world's largest investors in the global credit markets, PIMCO remains well-positioned to take advantage of differentiated performance within credit markets. In our view, the potential for rising interest rates and tighter credit markets heightens the need for active management. In recent years, falling interest rates and tightening credit spreads have boosted returns for passive and lower-active-risk LDI approaches. But with interest rates potentially on the rise and credit markets fairly valued, we are unlikely to witness another tide that lifts all boats. With beta, or benchmark, returns likely to be lower, excess returns take on added significance. In summary, we believe that today's environment continues to offer strong alpha opportunities. However, alpha is unlikely to stem from higher-beta risk as much as a thorough understanding of changing macro conditions and robust bottom-up credit research. Nonetheless, investors must recognize that markets are going to be more challenging to navigate than those of the last seven or eight years. Thus, we believe investors should seek to partner with investment managers with a deep bench of resources and experience in managing LDI portfolios through challenging environments (e.g., expertise in managing LDI portfolios in rising rate environments or knowhow in managing credit during spread-widening cycles). Q: PIMCO is a large player in U.S. long corporate bonds and many other markets. Is this an impediment to adding value in those portfolios? A: Not at all. In fact, we view our size as a unique advantage. The scale of our business allows us to have large teams of credit analysts and portfolios managers. This is increasingly important: In the last five years, for instance, the number of companies in the Bloomberg Barclays U.S. Long Credit benchmark has grown by about 25%, from 340 to 430 firms. Understanding how companies and sectors will evolve requires human and technological resources. Indeed, we believe our scale engenders many advantages: It helps us navigate changing liquidity conditions. With banks facing tighter post-crisis regulation, they have reduced their market-making function in credit markets. On several occasions, PIMCO has stepped up to become a liquidity provider. It can allow us to partner with companies to provide financing through reverse inquiries. In June, The Wall Street Journal highlighted how scale may create value in fixed income investing (see "In the New Bond Market, Bigger Is Better"). It gives us the resources to develop custom solutions and track risk against bespoke benchmarks and compliance regulations. LDI management requires customized glide paths and benchmarks with unique compliance regulations. Our size also enables us to have a deep bench of resources in pension solutions, compliance and risk management to develop customized solutions for clients and track risk against their liabilities. Finally, it helps us capitalize on the growth of passive investing, which has created a unique potential to add further alpha for our clients. Passive strategies buy and sell securities as benchmarks change (for instance, when securities get upgraded or downgraded). This often results in inefficiencies that can create opportunities for large asset managers like PIMCO. We recently explored this issue in "Bonds Are Different: Active Versus Passive Management in 12 Points." Q: Risk management is also a critical aspect of actively managed LDI portfolios. Could you discuss PIMCO’s risk management approach and how it applies to LDI portfolios? A: In LDI space, risk is often defined as the potential for (significant) divergence between the performance of assets and liabilities as market conditions fluctuate. As such, the first step in our risk management process is to develop a robust understanding and measurement of a client’s liability risk profile. We use several proprietary tools to measure and quantify liability risk exposure. Next, we design portfolio guidelines, objectives and benchmarks based on that liability risk exposure as well as our clients’ willingness and tolerance for risk. From there, we position the actively managed portfolio around liability targets or benchmarks with the objective of exceeding that benchmark return by an amount that is commensurate with the investor’s risk tolerance. We apply a robust risk management process that helps us scale deviations around the benchmark to an appropriate level in order to stay within the client’s risk tolerance objectives. To carry this out, PIMCO uses a wide range of proprietary analytics tools. We have always believed that to make independent decisions, it's essential to control the means for analyzing potential investments. As a result, we have devoted significant resources to building a library of in-house analytical software that helps to identify and quantify the risks inherent in different portfolio structures and strategies, specific bond market sectors, and securities within those sectors. Over the years, this effort has grown considerably. Although third parties provide similar tools, we seek to add value with our proprietary models. In-house development by portfolio managers and financial engineers enhances the quality of our models and increases portfolio managers' understanding of the results, since all analytical tools depend on input assumptions. Moreover, because we developed our systems in-house, we are well-positioned to quickly create new tools or enhance existing ones in response to product or market changes. We recognize, of course, that the coming three to five years will likely present unique challenges. Potential risks include rising geopolitical tensions, the consequences of debt creation over the last five years and the likely reduction of monetary policy support. That said, with our 250-plus portfolio management team, external advisors and client service teams, PIMCO remains committed to seeking consistent alpha for the benefit of its clients.
