Rob Arnott, founder and chairman of Research Affiliates, discusses how the All Asset strategies seek to avoid asset class bubbles while potentially benefiting from “anti-bubbles,” while Jim Masturzo, head of asset allocation at Research Affiliates, discusses what is driving net yields for the All Asset strategies relative to mainstream stocks and bonds. John Cavalieri, asset allocation strategist for PIMCO, explains the rationale for the upcoming change to the primary benchmark for All Asset All Authority. As always, their insights are in the context of the PIMCO All Asset and All Asset All Authority funds.

Q: How are the All Asset strategies positioned to take advantage of opportunities when so many markets have historically low yields and high valuations – what many are calling ‘bubbles’?  

Arnott: Before we turn to the opportunities that the All Asset strategies seek to capture, let’s first define “bubble.” We define a bubble as having two characteristics. First, we view the asset or market as expensive relative to its potential future growth and income, such that it has little chance of delivering better future returns (a “risk premium”) relative to U.S. government bonds or cash. This can be gauged using a generally accepted valuation model, like a discounted cash flow model, with a plausible projection of future cash flows. Second, the marginal buyer of the asset or asset class in a bubble appears to have little interest in valuation models, presumably buying based on a popular narrative and expecting to resell the asset to someone else at a higher future price. And apparently hoping the market will signal when it’s time to sell!

In recent publications1 we have explored both bubbles and the “anti-bubbles” we see in certain markets today. We define an anti-bubble as effectively the opposite of a bubble. It is a market that requires what we view as implausibly pessimistic assumptions in order not to beat bonds and cash when using a standard valuation model. In addition, in an anti-bubble, the marginal seller appears to have no interest in valuation models, which may be indicating the asset is undervalued. 

We believe these definitions can help in seeking to identify a bubble or anti-bubble in real time, instead of years after the fact.

It bears mention that while an individual stock (or other asset) can be a bubble, an individual asset generally cannot be an anti-bubble; almost any single asset can go to zero. Furthermore, bubbles continue to reward investors – and anti-bubbles continue to punish investors – until the bubble or anti-bubble bursts. This is why we think averaging into the anti-bubble stocks (and out of the bubble stocks) is so important: Make too large a bet too soon, and you can get hurt.

So, how do the All Asset strategies seek to avoid the trap of current bubbles and instead seek out anti-bubbles and assets that are likely undervalued? The key is that the All Asset strategies are designed to 1) systematically shift an investor’s exposure away from bubble assets (which admittedly could mean missing late-stage trending markets, even though that may be akin to picking up nickels in front of a steamroller); 2) diversify across investments that we believe are not in bubble territory; and 3) seek out anti-bubble opportunities. A disciplined contrarian, value-oriented trading approach is at the heart of this investment process, which averages out of the expensive, beloved markets and into inexpensive, out-of-favor markets – uncomfortable trades that go against most investors’ evolutionary wiring to follow trends.

As we look across global asset classes, emerging markets – most notably unloved emerging market (EM) value stocks and state-owned enterprises – fall squarely within our anti-bubble camp. As of 31 July 2019, allocations to EM asset classes amounted to 38.7% in the All Asset strategy and 45.0% in the All Authority strategy.2 While emerging markets as a whole currently trade at much more attractive valuations than the U.S. markets, value strategies within emerging markets are even cheaper, with the gap between growth and value in record territory (as proxied by the MSCI Emerging Market Growth and Value indices). Our models indicate that EM value stocks have potential to deliver an additional performance advantage over their broader cap-weighted market benchmarks over the next decade.

Along with seeking anti-bubbles in the EM arena, the All Asset approach aims to reduce investors’ exposure to bubbles in equities by largely avoiding cap-weighted index exposures, especially late in market cycles. Instead, the All Asset funds allocate to a range of PIMCO equity funds that are based on the Research Affiliates’ Fundamental Equity strategy, which seeks to sever the link between stock price and portfolio weights by systematically rebalancing to portfolio weights that are based on measures of fundamental business scale. As of 31 July 2019, total allocations to this family of funds are 39.1% in All Asset and 48.3% in All Authority.3

Lastly, we reiterate that the trajectory of a bubble or an anti-bubble (and the conditions underlying it) will, by its nature, continue until it turns. Without this expectation, the bubble would collapse immediately. Our approach of systematically dollar-cost averaging into our positions is designed to harvest incremental return over the long term. A disciplined process that continually tilts away from markets that appear overvalued and into markets that may be unjustifiably deemed cheap may potentially reward those who are steadfast, patient, and willing to accept some short-horizon maverick risk. We aim to position our investors to benefit when the anti-bubble eventually turns, or the bubble inevitably bursts.

Q: What are the key drivers of the All Asset funds’ net yields?

Masturzo: Let’s begin with some context: namely, how the yields of mainstream assets have trended this year, and why an understanding of yield levels matters for investors.

A central market theme of 2019 has been the continuing pullback in interest rates, with the U.S. 10-year Treasury yield closing the second quarter at around 2% and falling further from there. Equity yields have been no better, with the S&P 500 dividend yield coming in at 1.9% for the second quarter (according to Bloomberg), or a bit higher if share buybacks are considered, but still lower than the long-term historical average. The low yields are largely a result of the strong and extended bull market in mainstream assets, in which prices have grown faster than cash flows. 

This context matters when looking ahead because yield is an essential component in any model of expected return. To illustrate the point, consider a very simple and purely hypothetical asset: a default-free zero-coupon bond, held to maturity. For this asset, its yield is both its expected return today and also, by definition, its realized return to maturity in the future. While other assets or portfolios of assets may have more complex dynamics, yield is still an essential ingredient in the expected return. With this in mind, it makes sense to look at the yield of the All Asset funds, as well as to understand the current contributors to that yield.

As with many things in finance, not everyone agrees on a single definition of yield. For regulatory purposes, PIMCO cites two types of yield for each of its funds – distribution yield and SEC yield4 – each with its own underlying assumptions. As Figure 1 shows, despite differences in how these yields are defined, their values have been similar in most periods for the All Asset funds. 

The distribution yield in both funds has been rising since 2016 and is currently (as of 30 June  2019) 4.83% for All Asset Fund and 5.15% for All Asset All Authority Fund. In fact, with only a few exceptions (10.4% of the time for All Asset Fund and 9.6% of the time for All Asset All Authority Fund), both All Asset funds have maintained a distribution yield above 4% for their monthly reporting periods over the last 16 and 15 years, respectively. Although yields in the past few years have been lower than in early periods for these strategies, this trend is in line with reduced yields for most major asset classes.

Distribution and SEC yields for the All Asset funds are up since 2016

These yield levels are largely a result of the structural orientation of the funds.  The All Asset model underlying the strategies is based on a series of expected returns of which yield is a core building block.  The funds’ disciplined investment process and orientation toward diversifying “Third Pillar” assets mean that EM stocks and bonds, absolute return strategies, high yield bonds, and real return strategies have been key sources of yield.

Moreover, many of the underlying PIMCO funds that we use employ a “PLUS” strategy, which seeks to provide capital-efficient, two-in-one yield-enhancing potential within a single fund. For example, a fund might aim to provide exposure to a primary asset class, such as equities or commodities, through the use of futures contracts or total return swaps, and also fully collateralize those positions with high quality fixed income. We believe this is a capital-efficient approach to seeking a structurally higher yield in a risk-prudent manner, while still limiting tracking error to the underlying fund’s primary benchmark.

Also, our emphasis on RAE equity strategies (versus market cap-weighted equity strategies) offers an additional potential yield premium, given the value orientation of RAE. 

Finally, our ability to invest across a range of PIMCO’s more liquid absolute-return strategies as an alternative source of low-beta “dry powder” can also offer potential yield enhancement when used in lieu of traditional dry-power allocations, such as short-term and core bond strategies, given today’s low yields in those areas. 

While the funds’ yields may seem attractive in isolation, it is important to remember that these yields do not include the potential incremental return from capital appreciation or income growth from the underlying markets, or the potential for active manager alpha from tactical asset allocation or security selection within the underlying PIMCO funds. Taking all of these factors – including the related investment risks – into account, we believe the All Asset and All Authority strategies are well positioned.

Q: What is the rationale for the upcoming change to the primary benchmark for the PIMCO All Asset All Authority Fund?

Cavalieri: On 13 September 2019, PIMCO filed a prospectus update for the PIMCO All Asset All Authority Fund indicating that the fund’s primary benchmark will change from the S&P 500 to the Bloomberg Barclays U.S. TIPS Index, effective 1 October 2019. 

There is no change to the fund’s secondary benchmark, Consumer Price Index (CPI) + 6.5%, and there are no changes to the primary or secondary benchmarks for the PIMCO All Asset Fund, which remain the Bloomberg Barclays U.S. TIPS 1-10 Year Index and CPI+5%, respectively.

Why did we make this change for All Asset All Authority? In short, the goals are to improve clarity for shareholders regarding the nature of the fund’s investment strategy and to provide a more relevant point of comparison for returns. 

Recall that the All Asset strategies are designed to seek maximum long-term real returns while diversifying investors away from mainstream U.S. equities. To that end, All Asset All Authority has historically had a low average U.S. equity beta (0.34) and net negative average exposure to U.S. equities (-11.6% of net assets) as of 30 June 2019, since inception. So while the S&P 500 is often used as a primary benchmark for asset allocation funds – which typically have equity-centric approaches – its use in the context of the highly diversifying All Asset All Authority strategy seemed less appropriate. 

By contrast, U.S. Treasury Inflation-Protected Securities (TIPS) share an explicit real return orientation with the fund, and we believe the TIPS index better aligns with the fund’s return and risk attributes (e.g., higher correlation and beta, and lower tracking error), as shown in Figure 3.

Comparative statistics for PIMCO All Asset All Authority Fund (10/31/2003 - 7/31/2019)

In addition, changing All Asset All Authority’s primary benchmark to the Bloomberg Barclays U.S. TIPS Index creates better alignment with the All Asset Fund, which similarly uses a U.S. TIPS index as its primary benchmark.

Importantly, nothing else is changing with respect to All Asset All Authority Fund. The investment process and team remain the same, as does the fund’s secondary benchmark of CPI+6.5%, which we believe investors look to as an indication of the fund’s long-term real return aspiration. 

We believe investors in All Asset All Authority (and its sister fund, All Asset) appreciate that these strategies emphasize diversifying and inflation-sensitive “Third Pillar” markets (including real assets, emerging markets, and high yield bonds) as their allocation home base, not mainstream U.S. stocks. As such, our hope is that moving from the S&P 500 to the U.S. TIPS index as All Asset All Authority’s primary benchmark will reinforce the diversifying and real return nature of the strategy, and as a result provide a more relevant point of comparison for past and future returns.

The terms “cheap” and “rich” as used herein generally refer to a security or asset class that is deemed to be substantially under- or overpriced compared to both its historical average as well as to the investment manager’s future expectations. There is no guarantee of future results or that a security’s valuation will ensure a profit or protect against a loss.

The performance figures presented reflect the total return performance for the Institutional Class shares (after fees) and reflect changes in share price and reinvestment of dividend and capital gain distributions. All periods longer than one year are annualized. The minimum initial investment for Institutional class shares is $1 million; however, it may be modified for certain financial intermediaries who submit trades on behalf of eligible investors.

Investments made by a Fund and the results achieved by a Fund are not expected to be the same as those made by any other PIMCO-advised Fund, including those with a similar name, investment objective or policies.  A new or smaller Fund’s performance may not represent how the Fund is expected to or may perform in the long-term.  New Funds have limited operating histories for investors to evaluate and new and smaller Funds may not attract sufficient assets to achieve investment and trading efficiencies.  A Fund may be forced to sell a comparatively large portion of its portfolio to meet significant shareholder redemptions for cash, or hold a comparatively large portion of its portfolio in cash due to significant share purchases for cash, in each case when the Fund otherwise would not seek to do so, which may adversely affect performance.

Differences in the Fund’s performance versus the index and related attribution information with respect to particular categories of securities or individual positions may be attributable, in part, to differences in the pricing methodologies used by the Fund and the index.

There is no assurance that any fund, including any fund that has experienced high or unusual performance for one or more periods, will experience similar levels of performance in the future. High performance is defined as a significant increase in either 1) a fund’s total return in excess of that of the fund’s benchmark between reporting periods or 2) a fund’s total return in excess of the fund’s historical returns between reporting periods. Unusual performance is defined as a significant change in a fund’s performance as compared to one or more previous reporting periods.

A word about risk:

The fund invests in other PIMCO funds and performance is subject to underlying investment weightings which will vary. Investing in the bond market is subject to risks, including market, interest rate, issuer, credit, inflation risk, and liquidity risk. The value of most bonds and bond strategies are impacted by changes in interest rates. Bonds and bond strategies with longer durations tend to be more sensitive and volatile than those with shorter durations; bond prices generally fall as interest rates rise, and the current low interest rate environment increases this risk. Current reductions in bond counterparty capacity may contribute to decreased market liquidity and increased price volatility. Bond investments may be worth more or less than the original cost when redeemed.  Investing in foreign denominated and/or domiciled securities may involve heightened risk due to currency fluctuations, and economic and political risks, which may be enhanced in emerging markets. Commodities contain heightened risk including market, political, regulatory, and natural conditions, and may not be suitable for all investors.  Mortgage and asset-backed securities may be sensitive to changes in interest rates, subject to early repayment risk, and their value may fluctuate in response to the market’s perception of issuer creditworthiness; while generally supported by some form of government or private guarantee there is no assurance that private guarantors will meet their obligations. High-yield, lower-rated, securities involve greater risk than higher-rated securities; portfolios that invest in them may be subject to greater levels of credit and liquidity risk than portfolios that do not. Investing in securities of smaller companies tends to be more volatile and less liquid than securities of larger companies.  Inflation-linked bonds (ILBs) issued by a government are fixed-income securities whose principal value is periodically adjusted according to the rate of inflation; ILBs decline in value when real interest rates rise. Treasury Inflation-Protected Securities (TIPS) are ILBs issued by the U.S. government. Equities may decline in value due to both real and perceived general market, economic, and industry conditions. Entering into short sales includes the potential for loss of more money than the actual cost of the investment, and the risk that the third party to the short sale may fail to honor its contract terms, causing a loss to the portfolio. The use of leverage may cause a portfolio to liquidate positions when it may not be advantageous to do so to satisfy its obligations or to meet segregation requirements. Leverage, including borrowing, may cause a portfolio to be more volatile than if the portfolio had not been leveraged. Derivatives and commodity-linked derivatives may involve certain costs and risks such as liquidity, interest rate, market, credit, management and the risk that a position could not be closed when most advantageous. Commodity-linked derivative instruments may involve additional costs and risks such as changes in commodity index volatility or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. Investing in derivatives could lose more than the amount invested.  The cost of investing in the Fund will generally be higher than the cost of investing in a fund that invests directly in individual stocks and bonds.  Diversification does not ensure against loss.

Portfolio structure is subject to change without notice and may not be representative of current or future allocations. There is no guarantee that these investment strategies will work under all market conditions or are suitable for all investors and each investor should evaluate their ability to invest long-term, especially during periods of downturn in the market. Investors should consult their investment professional prior to making an investment decision.

Alpha is a measure of performance on a risk-adjusted basis calculated by comparing the volatility (price risk) of a portfolio vs. its risk-adjusted performance to a benchmark index; the excess return relative to the benchmark is alpha. Beta is a measure of price sensitivity to market movements. Market beta is 1. Correlation is a statistical measure of how two securities move in relation to each other. The correlation of various indexes or securities against one another or against inflation is based upon data over a certain time period. These correlations may vary substantially in the future or over different time periods that can result in greater volatility. Duration is the measure of a bond's price sensitivity to interest rates and is expressed in years. R-Squared is a statistical measure that represents the percentage of a portfolio's movements that can be explained by movements in a benchmark index. Standard deviation is a measure of the dispersion of a set of data from its mean. The more spread apart the data, the higher the deviation. Tracking error measures the dispersion or volatility of excess returns relative to a benchmark.
