- Preferred stocks are hybrid instruments that exhibit the characteristics of both equity and debt securities. Their unique credit quality, security structure, coupon type, and volatility profiles can help them serve as an attractive diversifier in a multi-asset portfolio.
- In the current market environment, preferred stocks have felt pressure from rising interest rates but have performed relatively well versus other high-yielding instruments.
- We believe this outperformance could continue if economic growth continues to support U.S. credit issuers and should equity markets remain stable. Tailwinds for the broad universe of preferred stock also include relatively strong capitalization of financial institutions, strong U.S. economic fundamentals, and their floating rate characteristics.
Overview of preferred stocks
Preferred stock is a special type of equity share class that shares some properties of both equity and debt instruments. The security lies in the middle of a company's capital structure - above common stock in the event of liquidation, but below traditional debt. This caveat presents a subordination risk that is priced into preferred stock's price and yield, which helps explain why preferred stock tends to yield higher than traditional bonds.
Banks and financial institutions are the main issuers of these securities because they can help satisfy regulatory requirements to support their liabilities. This is reflected in major indexes - the sector composition of the S&P U.S. Preferred Stock Index is about 84% financials and real estate.

For investors, preferred stocks offer a variety of potentially attractive portfolio functions. Since they can appreciate like a stock but pay coupons like a bond, they can provide investors distinctive benefits. Those include:
1. Higher yield potential: As discussed, preferred stocks typically have higher yields than their corresponding corporate debt counterparts. Chart 2 highlights how the 12-month trailing index yield of the S&P U.S. Preferred Stock Index has been higher than many fixed income exposures. The increased income potential drives an obvious argument for their addition to a fixed income portfolio.

Notes: Yield is represented by the yield to redemption for fixed income assets. The S&P Preferred stock's yield is represented by its 12-month trailing yield.1 Index performance is for illustrative purposes only. Index performance does not reflect any management fees, transaction costs or expenses. Indexes are unmanaged and one cannot invest directly in an index. Past performance does not guarantee future results.
2. Favorable risk characteristics: Despite their relatively high yields, the risk characteristics of preferred securities have recently been more favorable than those of equities and some fixed income assets. The reason why is intuitive: Issuers of preferred securities have benefited from strengthened fundamentals in the post-crisis growth regime, boosting their creditworthiness and diminishing their perceived riskiness. On the equity side, the limited direct equity participation of preferred shares can help minimize their volatility relative to pure equity exposures. Chart 3 shows how the addition of preferreds to a fixed income portfolio has increased income and reduced risk in potential portfolios as the allocation to preferreds is increased.

Notes: The "no preferreds" portfolio is comprised of a 25% allocation to the iBoxx $ High Yield Corporate Bond (NYSEARCA:HYG), Markit iBoxx USD Liquid Investment Grade, Bloomberg Barclays Agg, and JPMorgan EM Bond Indexes. The subsequent portfolios continue 23.75%, 22.5%, and 20% to the 5%, 10% and 20% preferred portfolios.2 Preferred stocks are represented by the S&P U.S. Preferred Stock Index.

3. Diverse return stream: Preferred stocks have lower historical correlations to traditional stocks and bonds, which means they tend to move in different directions when market conditions change. Depending on the market environment, this may allow preferred shares to help mitigate downside risks from falling equity markets.

4. Credit quality diversification: The credit quality of preferred stock issuers varies significantly across issuers. At the index level, we find that 80% of the securities within the S&P Preferred Stock Index have a credit rating from BBB+ to B-. The higher skew toward the BBB+ rating than in high yield benchmarks can help explain why the broad index has a lower yield than high yield, but higher yield than investment grade (figure 5).

Preferred stock in the current market environment
It's important to note that preferreds have performed well in 2018 relative to other higher-yielding, longer-duration products with similar yield profiles. While it is true that preferred stocks may see price declines along with other traditional long-term bonds in a rising rate environment, the losses may be offset by the potential yield and equity appreciation.
Additionally, because we expect the rate rises to be gradual, we wouldn't expect to see big downward spikes in preferred prices. Preferred stocks may also be attractive due to the fact that they're issued mainly by financial companies, which have historically tended to do well in rising rate environments. For example, monthly returns of the S&P 500 Financial Sector Index have a 0.54 correlation to changes in the 2-year U.S. Treasury yield over the last five years, which is greater than the 0.3 correlation to the 2-year to the S&P 500.4
Key risks to monitor include those broadly to other asset classes: trade war developments, rapid tightening of financial conditions, and a slowdown in global growth. While we do not expect the latter two to occur soon, the former is difficult to forecast. Historically, preferreds have helped insulate equity investors from pure equity market drawdowns, but they typically lose more than IG and HY counterparts.

Historically, the higher yields, diverse return streams and credit quality, and favorable risk characteristics have provided preferred investors with a complement to their multi-asset portfolios. During periods of rising interest rates, preferreds have done well versus other fixed income exposures given their high tilt toward financials and equity-like upside. Still, preferred stocks may continue to feel pressure from rising interest rates. Elsewhere, tightening financial conditions and trade war risks are broad risks to monitor for preferred stock. Nonetheless, the merits of preferred stocks may be appropriate for multi-asset investors looking to diversify their return streams and source of yield.

1 Yield to redemption is the annualized rate of return an investor would receive if they held the bond to maturity (redemption). The 12-month trailing yield is the percentage of income an investment has paid out in the past 12 months.
2 The equal-weighted allocation to the identified indexes was selected as to represent a hypothetical global bond portfolio. In order to demonstrate the potential risk and yield profile of incrementally adding an allocation to preferred stocks, the weights between the original four indexes were reduced equally. Risk is represented by the annualized standard deviation of daily returns from August 2013 to August 2018.
3 Correlation is used in statistics to measure how strong a relationship between two variables is. It is calculated by taking the covariance of two variables and dividing it by the product of their individual standard deviations. The range of values for correlation is bounded by 1.0 on an absolute value basis or between -1.0 and 1.0.

Preferred stocks are not necessarily correlated with securities markets generally. Rising interest rates may cause the value of the Fund's investments to decline significantly. Removal of stocks from the index due to maturity, redemption, call features or conversion may cause a decrease in the yield of the index and the Fund.
Funds that concentrate investments in specific industries, sectors, markets or asset classes may underperform or be more volatile than other industries, sectors, markets or asset classes and than the general securities market.
Diversification and asset allocation may not protect against market risk or loss of principal.
Fixed income risks include interest-rate and credit risk. Typically, when interest rates rise, there is a corresponding decline in bond values. Credit risk refers to the possibility that the bond issuer will not be able to make principal and interest payments.
Non-investment-grade debt securities (high-yield/junk bonds) may be subject to greater market fluctuations, risk of default or loss of income and principal than higher-rated securities.
