Rising Stars
Rising Stars
A rising star is a high-yield bond upgraded to investment-grade (BB to BBB) by a rating agency. The upgrade triggers index inclusion, price gains, and automatic buying by constrained investors.
Key takeaways
- A rising star becomes an investment-grade bond when upgraded, causing investment-grade index funds to buy automatically.
- The upgrade announcement typically drives 2–6% price gains in a single day as spreads compress and index funds add the bond.
- Rising stars often become core holdings in portfolios: stable businesses that proved themselves over a 3–5 year period.
- Common paths to rising-star status include debt paydown, EBITDA growth, deleveraging, and market recognition of improved fundamentals.
- Investors who hold a rising-star candidate early (when it is still rated BB) benefit from both yield and the price appreciation upon upgrade.
What drives an upgrade to investment grade
A company rated BB (high-yield) can improve its credit profile through operational excellence, debt reduction, or business evolution. When metrics improve sufficiently, the rating agency upgrades it to BBB, and it becomes investment grade.
Common upgrade drivers:
1. Deleveraging: A company committed to paying down debt reduces leverage from 4x to 3x or below. The agency sees sustainable de-risking and upgrades. This is especially common for companies financed by private equity that execute a deleveraging roadmap post-acquisition.
2. EBITDA growth: A company grows its operating earnings faster than debt, causing leverage to fall naturally. Example: A telecom company grows revenue 5% annually while holding debt flat; after 5 years, leverage falls from 4x to 3x. Upgrade.
3. Market and business expansion: A company enters new geographies, products, or customer segments, diversifying revenue and reducing cyclicality. Example: A manufacturer expands from one region to multiple; revenues increase, margins stabilize, leverage falls. Upgrade.
4. Management execution: A new CEO or CFO executes a clear strategy for debt reduction and operational improvement. Over 2–3 years, results materialize, and the agency upgrades. Example: A struggling airline acquires smaller competitors, reduces costs, improves margins, and is upgraded from B to BB, then BB to BBB.
5. Market sentiment and technical factors: Sometimes upgrades reflect changing sentiment, not just improved metrics. A sector comes into favor (energy prices recover, tech spending increases), and companies in that sector see upgrades. The metrics may not have changed much, but the agency's view of the sector's future does.
The mechanics of rising from HY to IG
When a rating agency announces an upgrade from BB to BBB, three things happen:
1. Spread compression (immediate)
An IG bond (BBB) typically trades at OAS +100–150 bp. A HY bond (BB) trades at OAS +400–500 bp. When a bond is upgraded from BB to BBB, spreads compress. The 300 bp spread narrowing translates to an immediate 3–4% price gain on a 5–7 year bond, 5–8% on a 10-year bond.
Example: A 6-year bond trading at yield 5% (OAS +450) is upgraded. It now trades at yield 3.5% (OAS +100). The price moves from par (100) to 107. A bondholder or investor holding this bond realizes a 7% one-day gain.
2. Index inclusion and passive buying (T+1 to T+5 days)
When the upgrade is official, bond indices add the bond to their investment-grade portfolios. Passive funds tracking these indices automatically buy. If the bond was previously held by $300 million in active high-yield funds, it now must be held by investment-grade index funds (which might target $2 billion in holdings of similar credits).
This automatic demand is enormous: tens of millions to hundreds of millions of dollars in buying pressure can hit a single bond. On the day of index inclusion, the bond's bid-ask spread tightens (demand exceeds supply), and prices can rally another 1–3%.
3. Active investor rotation (T+1 to T+30 days)
High-yield investors who held the bond during its HY tenure can now sell to IG investors at the higher price. Active IG managers seeking new positions in their mandate buy the newly minted BBB bond. Some IG managers have mandates excluding bonds just-upgraded from HY ("new money" rules), while others actively seek newly upgraded names, viewing them as higher-yielding names with recent credit improvement visibility.
Price appreciation on upgrade
The combination of spread compression and index buying can drive significant price appreciation over a few days. Here's a realistic scenario:
Rising-star bond profile:
- 7-year maturity, 5.5% coupon.
- Rating: BB (pre-upgrade), trading at 98, OAS +425 bp, yield 5.9%.
On upgrade announcement to BBB:
- Spread compression: OAS widens to +125 bp (a 300 bp compression).
- Duration impact: On a 7-year bond, 300 bp compression ≈ 3–4% price gain.
- Price moves from 98 to 101–102.
- New yield: ~5.0% (5.5% coupon, slight premium).
On index inclusion (1–5 days later):
- Passive demand pushes price further.
- Price moves from 102 to 104.
- Yield drops to ~4.8%.
Final outcome:
- An investor who bought at 98 (before upgrade) realizes 6% price appreciation in a week, plus an ongoing 5.5% coupon. Total realized return over the subsequent year: 5.5% yield + 6% price appreciation = 11.5% (though the 6% is front-loaded into the upgrade week).
Identifying rising-star candidates: Credit analysis at the edge
Savvy investors identify rising-star candidates before the upgrade, profiting from both yield and the price appreciation.
Key signals of upgrade readiness:
1. Leverage trajectory: A company's debt/EBITDA is trending down. If it was 4.5x two years ago and is now 3.8x, with a 3x or below target, an upgrade is likely within 12–24 months. The agency's published guidance might specify "upgrade consideration at 3.2x leverage." An investor who spots the company at 3.3x with declining leverage can hold and await the upgrade.
2. Coverage ratio improvement: Interest coverage (EBITDA/interest expense) is rising, indicating less stress on debt service. A company with 2.5x coverage (tight) improving to 3.5x (comfortable) signals credit improvement.
3. Management guidance: Management commits to a leverage reduction target (e.g., "we will reach 3x within three years") and executes against it. An investor can monitor quarterly earnings calls to track progress.
4. Peer upgrades: When competitors in the same sector are upgraded, a company with similar metrics is next in line. Example: If two regional bank chains are upgraded from BB to BBB, a third with similar metrics is likely next.
5. Sector tail winds: A sector is improving. Energy companies' leverage improves as commodity prices rise; telecom companies delever as 5G rollout drives EBITDA growth. Investors in rising-star candidates within improving sectors benefit from both company-specific credit improvement and sector rotation.
6. CDS spread narrowing: Credit default swap spreads often lead rating upgrades by weeks or months. If a company's CDS has tightened from 300 bp to 150 bp, an upgrade is likely coming.
Rising stars vs. original investment-grade bonds
A bond upgraded to BBB (rising star) is mechanically identical to a bond issued at BBB originally, but it offers different characteristics to investors:
Rising star (upgraded BB to BBB):
- Likely carries a higher coupon (issued when BB; now yielding more than a new-issue BBB).
- Has a track record of credit improvement; investors have visibility to the company's deleveraging.
- May trade at a slight premium if the market is excited about the upgrade (technical buying from index funds).
- Often exhibits lower volatility going forward (credit trajectory is improving, not deteriorating).
Original investment-grade bond (issued at BBB):
- Lower coupon (issued at BBB, so priced accordingly).
- Less track record; the company has not proven it can improve or survive stress.
- Trades at market-clearing spreads for the sector.
- May face downgrade risk if the company's metrics deteriorate.
A portfolio manager comparing a rising star (say, 5% coupon, AAA secured) with a new-issue BBB bond (3.5% coupon, AA unsecured) might prefer the rising star if the 150 bp yield advantage offsets the slightly higher credit risk. The rising star has already weathered adversity and improved.
Cycles and mean reversion
Rising stars are not always successful. Some companies improve, are upgraded, then face new challenges and are downgraded again. The cycle can repeat, or the company can stabilize.
Example: Energy company cycle
2016: An oil & gas company is rated BB, leverage 4x, CDS 300 bp. Oil prices recover, EBITDA grows, leverage falls to 3.2x.
2018: Company is upgraded to BBB. Bond rallies 5%. CDS tightens to 150 bp.
2020: Oil prices crash (COVID shock). EBITDA collapses, leverage spikes to 5x. Company faces downgrade pressure. Bond falls 8–10%.
2021: Oil prices recover. Company survives. Downgrade pressure eases.
2022: Company deleverages aggressively, is re-upgraded to BBB. Bond rallies again.
Investors who held the 2018 upgrade realized gains but then experienced drawdowns in 2020. Those who bought on the 2020 decline and held to 2022 realized even larger returns. The cyclicality is important: rising stars in cyclical sectors can be volatile, and investors must understand the cycle.
Portfolio implications of rising-star holdings
For a portfolio manager holding a rising-star bond, the upgrade event has several implications:
1. Rebalancing: The bond now fits a different part of the portfolio. It must be moved from "high-yield sleeve" to "investment-grade sleeve." This can require portfolio reorganization.
2. Yield compression: The new BBB yield is lower than the old BB yield. A portfolio expecting a 5.5% coupon now receives 5% (if the bond is held post-upgrade). The portfolio's yield declined, a headwind for total return if not offset by price appreciation.
3. Risk profile shift: The bond is lower risk post-upgrade, but volatility can remain if the company is newly upgraded and the market is skeptical of the upgrade's permanence.
4. Opportunity cost: An investor who held the bond in its BB phase may decide to sell post-upgrade, realizing the 6% one-day gain, and deploy proceeds into a higher-yielding BB bond. This locks in the price appreciation and moves into a new idea.
Real-world examples of rising stars
Spotify (2022): Spotify, a music streaming company, was rated B and B+ by agencies as of 2020–2021, due to ongoing losses and high debt. As the company reached profitability (2021) and deleveraged, it was upgraded to BBB− (just barely investment grade) in 2023. Bonds issued in 2021 at high yields (5%+) traded at premiums by 2023, offering investors price appreciation and solid yield.
Starbucks (2007–2009): Starbucks was downgraded to BB during the financial crisis due to leverage from acquisition debt. As the company recovered and expanded in China, leverage fell, and Starbucks was upgraded back to BBB by 2010. Investors who held HY Starbucks debt or bought on the downgrade benefited from years of subsequent yield plus the upgrade-driven price gains.
AT&T (ongoing concern): AT&T has lingered at the BBB/BB boundary multiple times, downgraded and upgraded as debt levels and cash flow fluctuate. Investors who identified times when the company was approaching upgrade (leverage at 3.2x and falling) captured gains, while those who held after downgrades experienced losses.
