Bond Ladders
We generally do not recommend bond ladder strategies for institutional portfolios. Ladders typically lack sufficient diversification among sectors and issuers and transaction costs will be higher than a fund or SMA. Bond ladders are also likely to suffer from a cash drag. For example, the coupon interest may be too small to be reinvested at similar rates as the rest of the ladder and therefore earns lower money market returns instead of being reinvested at higher yields. Consequently, a ladder would be expected to generate lower returns than a comparable bond fund or SMA. If shorter duration is desired, a short-term bond fund or SMA might be able to accomplish that goal more efficiently than the ladder.
Bond ladders are sometimes perceived as simple, do-it-yourself strategies. However, finding the right bonds to purchase can be difficult given the complexity of fixed income markets. An understanding of the market and associated risks are required along with the tools to regularly monitor changing conditions. Bankruptcies, defaults and fluctuating interest rates are just some of the complexities that may challenge bond investors and the risks are only amplified with fewer individual positions. Even with comprehensive, up front analysis, an investor may not have the time or expertise to maintain constant monitoring of the portfolio, which is required to manage risks properly.
Separately Managed Accounts
A separately managed bond account can be a very good fit for larger asset balances, particularly where there are unique constraints and a need for customization. An organization that adheres to specific Environmental, Social and Governance (ESG) investing criteria and wishes to avoid certain issuers based on their ESG requirements may prefer separately managed accounts. Another example is a defined benefit pension plan that elects to customize the fixed income portfolio to match the liability characteristics of their plan to reduce funded status volatility.
Other benefits of bond SMAs include professional investment management, broad diversification of holdings (especially with larger SMAs) and generally lower investment expenses than a comparable bond fund. An investor that expects regular cash flows in or out of the SMA should consider the additional transaction costs associated with that trading activity (bid/ask spread). Frequent trading to either raise cash or invest cash contributions can add cost and therefore nullify the investment expense savings advantage that SMAs might offer relative to bond funds. Lastly, custody costs of a bond SMA present another consideration, as transaction-based custody fees may add to the total cost of the SMA as well.
Bond Funds
Bond funds are a good fit for most investors. They offer superior diversification for even very small balances. Funds are professionally managed and institutional share classes frequently carry competitive investment expenses. They also provide daily liquidity and often aggregate trading activity into larger trades that reduce transaction costs and the potential drag on fund returns. Bond funds do have to manage daily investor cash flows, but skilled fund managers monitor those trends closely. Most large bond funds maintain sufficient cash cushions to meet redemption requests without materially impacting the broader portfolio.
