American Century Select High Yield ETF (AHYB)

AHYB is an actively managed ETF that selects high-yield corporate bonds with qualities more typically associated with investment-grade debt — emphasizing issuers with stronger balance sheets and lower bankruptcy risk than the typical junk bond — aiming to capture high-yield income with reduced credit deterioration risk.

American Century Investments manages AHYB within the context of a broad fixed-income franchise. The fund operates on a simple but disciplined principle: the high-yield bond market contains a spectrum of credit quality, from companies barely below investment grade to those in financial distress. Rather than hold the entire market or chase the highest yields, AHYB’s managers screen the universe for the highest-quality bonds available in the high-yield segment — names that could be investment-grade today or might become investment-grade tomorrow.

This selective approach creates a fund that yields more than investment-grade bonds (because it still owns sub-BBB rated debt) but carries less credit risk than a broad high-yield fund that owns bonds from severely distressed issuers. The portfolio typically includes 100 to 200 individual bonds, reflecting a focused selection strategy rather than a broad market approach.

Core holdings: rising-star companies and quality issuers

The fund’s first segment is high-yield bonds from companies that are fundamentally sound but technically rated below investment grade. These might be younger, high-growth companies (software, healthcare, financial services) that have invested heavily and carry debt but have strong operational momentum. A technology company rated B+ with clear revenue growth and positive cash flow generation is fundamentally different from a struggling retail company rated B- with declining sales and no clear path to stability. AHYB leans toward the former.

The second segment is bonds from companies recently downgraded from investment grade into the high-yield universe. These “fallen angels” often carry fading problems — perhaps a cyclical downturn in their industry has depressed profits — that may be temporary. If the business recovers, the credit rating follows, and the bond appreciates as it normalizes. American Century’s managers hunt for cyclical downgrade situations where the company’s long-term credit quality has not deteriorated, only its near-term earnings have weakened.

The third segment is bonds from mature, established companies with stable cash generation that happen to be rated high-yield only because of capital structure decisions — heavy debt loads taken on for acquisitions or buyouts. These issuers have the cash flow to service their debt even through economic downturns; the risk is not bankruptcy but leverage reduction taking time. A telecommunications company with high leverage but stable, regulated revenue streams falls into this category.

The fund generally avoids the deepest-risk segment of high-yield: bonds from companies in structural distress, with deteriorating market positions, or in industries facing existential threat. It also avoids forcing yield by buying the most distressed debt; if a bond is yielding 12 percent, the market is pricing in substantial risk, and AHYB’s managers prefer 6 to 7 percent yield on sounder credits rather than reach for 10 percent on damaged ones.

What this selectivity costs

AHYB’s expense ratio reflects active management — the cost of credit research, portfolio monitoring, and trading high-yield bonds. Because the fund holds a smaller, more curated portfolio than a broad high-yield index fund, it will not participate fully in rallies driven by the riskiest high-yield debt, and it may avoid the worst losses when the deepest-distressed bonds implode. The trade-off is deliberate: give up some upside participation in exchange for lower downside.

The fund’s concentration in higher-quality segments of high-yield means it will underperform a broad high-yield index fund during periods when the entire market is rallying and credit is improving broadly. It will also underperform during speculative explosions when capital seeks yield at any cost and lends to marginal credits at tight spreads. But in credit downturn cycles, when high-yield spreads widen and the weakest credits default, AHYB’s quality bias should cushion the losses.

Income and volatility

AHYB distributes the coupon income from its bond holdings, making it income-producing. The fund’s share price fluctuates with the market value of the underlying bonds, moving with changes in credit spreads (the extra yield investors demand for holding corporate debt over risk-free Treasuries) and overall interest rates. In stable credit environments, the fund provides steady income with modest price appreciation. In credit crises, the price can decline sharply as spreads widen and credit losses flow through the portfolio.

Who uses AHYB

Conservative high-yield investors use AHYB as a way to capture the yield premium of high-yield bonds without taking maximum leverage and credit risk. Insurance companies and pension funds sometimes use it as part of a credit diversification strategy, owning some of the higher-quality end of junk bonds without being forced to own the most distressed credits. Individual investors seeking income sometimes prefer AHYB to a broad high-yield index fund, accepting the narrower yield in exchange for what they hope is a lower probability of sharp losses.

The fund is suitable for investors who understand that high-yield bonds are corporate debt, not equities, and that credit cycles are real. A recession or credit event can significantly reduce the fund’s value in a matter of months. The selectivity AHYB brings reduces that risk relative to a broad high-yield fund, but does not eliminate it. Anyone considering AHYB should compare it to both investment-grade bond funds and broad high-yield funds, and decide whether it sits in a sweet spot in their portfolio or whether a clearer bet on either credit quality or credit yield is preferable.
