What Is a Fallen Angel?
A fallen angel is a company whose credit rating drops below the investment grade cutoff of BBB- at S&P and Fitch or Baa3 at Moody's, pushing its bonds into high-yield indices. The term distinguishes these issuers from companies that were rated speculative grade from the start, since fallen angels tend to be large, established businesses hit by a downturn, a leveraging event, or an industry shock.
The reverse trajectory has a name too: a rising star is a high-yield issuer upgraded back into investment grade. Together the two flows define the boundary traffic between the two credit markets, and strategists track the volume of each as a barometer of overall corporate credit health.
How a Downgrade to Junk Plays Out
Because index rules typically classify a bond by its middle rating, a company usually becomes a fallen angel once a second agency cuts it below investment grade. At that point the bonds exit investment grade indices at the next rebalancing, and funds benchmarked to those indices must sell regardless of price. That forced selling frequently pushes prices below what the fundamentals justify.
The high-yield market then has to absorb the debt, and fallen angels are often the largest issuers in it. Their bonds usually carry the looser covenants and longer maturities of investment grade paper, which makes them structurally different from bonds born in high yield. Research on fallen angel indices has repeatedly found that they outperform the broader high-yield market over time, precisely because the initial selling is mechanical rather than fundamental.
Why It Matters
The classic modern example is Ford. When S&P cut the automaker to junk in March 2020, roughly $36 billion of its bonds migrated into high-yield indices, the largest fallen angel event on record at the time. The bonds sold off hard, then rallied as markets stabilized, and Ford eventually earned upgrades back to investment grade in 2023, completing the round trip to rising star.
For students targeting credit roles, fallen angels are a favorite interview topic because they connect ratings mechanics, index construction, forced selling, and value investing in one story. Desks that anticipate downgrades can position ahead of the forced flows, and distressed or crossover funds screen cusp-rated BBB- names for exactly this setup.
