Understanding Recent Convertible Market Performance

Historically, U.S. convertible securities have offered an attractive risk/return profile. From 1988 through 2021, the ICE BofA U.S. Convertible Index captured about 80% of the upside and 60% of the downside of the average rolling 12-month returns of the S&P 500, NASDAQ Composite, and Russell 2000 indices.1 Even when the S&P 500 exceeded or declined by more than 10% in any given quarter, convertibles continued to exhibit asymmetric returns relative to equities (Figure 1). Recent relative performance has been weaker. In 2021, the three equity indices rose 28.7%, 22.2%, and 14.8%, respectively, for a 21.9% average return; the convertible index returned 6.3%, or 29% of the equity indices’ average. Year-todate through April 2022 downturn, the average return for these three equity indices was (16.9)%, while convertibles returned (12.1)%, participating in about 72% of the decline.

Convertibles had particularly poor performance relative to the S&P 500 for several reasons (Figure 2). The best performing sectors in the S&P 500, such as Energy and Materials, have a very low representation in the convertible benchmark. In addition, the mega cap companies that performed exceptionally well in 2021, such as Apple, Microsoft, and Alphabet, have no representation at all in the convertible market.

Convertibles Look Attractive vs. Other Debt Instruments

We think investors should view convertibles as an alternative slice of their bond allocation. Unlike straight bonds. convertibles historically have a negative correlation to interest rates, because convertible bond performance is largely driven by the performance of the issuer’s equity. In periods when interest rates and inflation rise, equities tend to advance in tandem with corporate profits. Also, convertibles do not necessarily mature at their nominal $1,000 par value. If the underlying equity rises above the bond’s conversion price, the bond can be converted into cash or common stock worth more than the bond’s par value. Owning a fixed-income security with performance relatively independent of interest rates and with capital appreciation potential may be an advantage in the current market environment (Figure 3 below and Figure 4 on the following page).

The sharp selloff in the stocks of many companies in 2021 that had recently issued convertible bonds has created an attractive opportunity for convertible investors, in our view. Many of these bonds are now trading below 90, in some cases very close to their theoretical bond floors, and many offer yields to maturity of 2% to 7%. These bonds are not “busted,” (their imbedded call options are not worthless), so there exists the capital appreciation potential if the underling share price recovers. For example, the convertible bonds of a game developer were trading near 90 recently. When the issuer announced it was being acquired, the bonds rose to 102.

Convertible bonds trading close to their theoretical bond floors pose relatively little downside risk, unless the company becomes financially distressed or interest rates rise significantly. Since most of these convertible securities are notes that mature in two to five years, their interest rate risk is relatively low. One downside, however, is that most of these instruments were issued with minimal cash coupons and their current cash yields are generally very low or nonexistent, even if their yields-to-maturity are attractive.

Adding convertible bonds to a traditional fixed income portfolio also offers the benefit of exposure to sectors, such as Information Technology and Healthcare, with large weightings in the convertible universe but little or no weight in most fixed income benchmarks.

While convertible bonds are usually the most volatile of fixed income securities, recent market dynamics may give investors an opportunity to capture potential favorable returns relative to other debt instruments.


MacKay’s Approach to US Convertibles

Since it’s inception, MacKay’s Convertible team has sought long-term fundamental value in actively managed portfolios. We largely own securities that we believe offer a measure of downside protection, issued by companies with strong business models whose underlying equities trade at reasonable valuations based on prospective free cash flow. The strategy generally has not fared well in speculative environments, when momentum and hype drove convertible performance. Fortunately, such markets are infrequent and generally short-lived: They have prevailed at least twice in the last quarter century, in the late 1990’s and in 2020. Our strategy’s relative performance was poor in both periods, and rebounded when the market corrected. 

In 2000, the MacKay Convertibles strategy returned 3.8% after fees and 4.3% gross, while the convertible index returned (10)%. In 2021, the MacKay Convertibles strategy outperformed in each quarter, generating an annual return of 9.7% after fees and 10.3% gross, while the Convertible Index returned 6.3%.3 Relative to peers, the strategy was top quartile for one-year returns.4

We don’t expect a correction ahead comparable to 2000, but we do think the market is likely to continue to favor securities with sound fundamentals and reasonable valuations when interest rates are no longer kept near zero and crowds of online speculators no longer divorce a company’s share price from its earnings prospects. We believe our strategy’s strong results in 2021 demonstrate the soundness of our investment approach in a market where valuations once again matter. 

1. Based on internal calculations comparing the rolling 12-month returns of the ICE BofA U.S. Convertible Index with the equal weighted average of the S&P 500, NASDAQ Composite, and Russell 2000 indices between 1988-2021.

2. Percentage capture determined based on average quarterly returns. Average quarterly returns calculated based on the relevant asset class’ performance in each calendar quarter where the S&P exceeded +10% or declined more than (10)%.

The Convertible Composite includes all discretionary convertible accounts managed with similar objectives for a full month, including those accounts no longer with the firm. This strategy primarily consists of convertible securities such as bonds, debentures, corporate notes, and preferred stocks or other securities that are convertible into common stock or the cash value of a stock or a basket or index of equity securities. The strategy may invest in debt securities that are rated investment grade and below investment grade or, if unrated, that we determine to be of equivalent quality. Gross-of-fees composite performance reflects reinvestment of income and dividends and is a market-weighted average of the time-weighted return, before advisory fees and related expenses, of each account for the period since inception. Net-of-fees composite performance is derived by reducing the quarterly gross-of-fees composite returns by 0.125%, our highest quarterly fee.

The three-year annualized standard deviation measures the variability of the composite gross returns and the index returns over the preceding 36-month period. 


Convertible securities are subject to a risk of loss. Convertible securities may be subordinate to other securities. The total return for a convertible security depends, in part, upon the performance of the underlying stock into which it can be converted. Additionally, an issuer may encounter financial difficulties which could affect its ability to make interest and principal payments. If an issuer stops making interest and/or principal payments, an investor could lose its entire investment. There can be no assurance that investment objectives will be met and there is no guarantee against loss.

Unlike the index, portfolios within the composite are actively managed and may also include derivatives. There is no guarantee that any of the securities in the index are contained in the portfolio. The performance of the index assumes reinvestment of dividends but does not reflect the impact of fees, applicable taxes or trading costs which, unlike the index, may reduce the returns of the portfolio. Investors cannot invest in an index. Because of these differences, the performance of the index should not be relied upon as an accurate measure of comparison.
