Goodwin argues against the passive "index-hugging" approach to credit focused on coupon payments and agency ratings. Diameter's edge comes from approaching credit like an equity long-short fund, constantly analyzing what macro and sector trends will change security prices over the next 3 to 24 months to generate total return.

A strategic divergence exists in EM corporate credit. Mandate-bound real money funds feel compelled to stay invested due to a lack of near-term negative catalysts, while more flexible hedge funds are actively taking short positions, betting that historically tight spreads will inevitably widen over the next 6-12 months.

Identifying flawed investments, especially in opaque markets like private credit, is rarely about one decisive discovery. It involves assembling a 'mosaic' from many small pieces of information and red flags. This gradual build-up of evidence is what allows for an early, profitable exit before negatives become obvious to all.

Traditional credit rotation strategies based on beta and starting spreads have become ineffective. Analysis now shows a sector's net supply—the volume of new debt issued versus what's maturing—is the most critical factor determining its relative performance, making technicals more important than fundamentals.

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.

The market is focused on potential rate cuts, but the true opportunity for credit investors is in the numerous corporate and real estate capital structures designed for a zero-rate world. These are unsustainable at today's normalized rates, meaning the full impact of past hikes is still unfolding.

Judging the credit market by its overall index spread is misleading. The significant gap between the tightest and widest spreads (high dispersion) reveals that the market is rewarding quality and punishing uncertainty. This makes individual credit selection far more important than a top-down market view.

In a market where spreads are tight and technicals prevent sustained sell-offs, making large directional bets is a poor strategy. The best approach is to stay close to benchmarks in terms of overall risk and allocate the risk budget to identifying specific winners and losers through deep, fundamental credit analysis.

Barclays' research shows that the best investment performance comes from combining fundamental analysts with systematic signals. The key is to filter out trades where the two perspectives diverge, as this method is exceptionally effective at eliminating potential losing investments and generating alpha.

A credit investor's true edge lies not in understanding a company's operations, but in mastering the right-hand side of the balance sheet. This includes legal structures, credit agreements, and bankruptcy processes. Private equity investors, who are owners, will always have superior knowledge of the business itself (the left-hand side).
