Conventional wisdom blames high fees and a "paradox of skill" for active management's failure. However, fees are at historic lows and increased manager skill should theoretically reduce market volatility. The fact that managers are performing worse despite these tailwinds indicates a deeper, structural market shift is the true cause.

Unlike discretionary managers with narrow focus, a systematic process has a view on every bond continuously. This allows it to act as a liquidity provider—trading opportunistically when others are forced to transact—and capture implementation alpha, effectively being 'paid to trade.'

In the post-zero-interest-rate era, the “everything rally” driven by liquidity is over. Higher base rates mean companies must demonstrate fundamental strength, not just ride a market wave. This environment rewards active managers who can perform deep credit selection, as weaker credits no longer outperform by default.

In bond investing, where upside is capped at a promised return, superior performance comes from what you exclude, not what you buy. The primary task is to eliminate the bonds that will default. Once those are removed, all the remaining performing bonds deliver a similar, contractually-fixed return.

Historically, investors sought active managers for outperformance (alpha). With the S&P 500 becoming a concentrated bet on a few tech stocks, leading Chief Investment Officers now justify using active management primarily as a way to achieve the broad-based diversification that the main index no longer provides.

BlackRock's CIO of Global Fixed Income argues that unlike equities, fixed income is about consistently getting paid back. The optimal strategy is broad diversification—tilting odds slightly in your favor and repeating it—rather than making concentrated, high-conviction "bravado" bets on specific market segments.

Contrary to equity investing where individual winners drive returns, the majority of alpha in credit comes from superior portfolio construction and risk management. The job is to avoid losers through a rigorous process, not to be a "star loan picker," as upside is inherently capped.

Contrary to the belief that indexing creates market inefficiencies, Michael Mauboussin argues the opposite. Indexing removes the weakest, 'closet indexing' players from the active pool, increasing the average skill level of the remaining competition and making it harder to find an edge.

While active equity funds often fail to beat benchmarks, active management in fixed income tells a different story. Allspring CEO Kate Burke notes over 90% of their active bond strategies outperform over multiple time horizons, attributing this success to deep, proprietary credit research.
