What Is a Weighted Average Credit Rating (WACR)?
The weighted average credit rating (WACR) pertains to the combined weighted average of all bond ratings within a bond fund. This metric enables investors to gauge the overall credit quality and risk level of a bond portfolio. The lower the weighted average credit rating, the riskier the bond fund tends to be. WACRs are categorized using letter ratings such as AAA, BBB, or CCC.
Key Takeaways
- WACR gives investors insight into a fund’s total credit quality, expressed in ratings like AAA, BBB, or CCC.
- It is calculated by assessing each individual credit rating’s value percentage within the entire portfolio to yield an average rating.
- Some argue that WACR may confuse investors who don’t fully grasp the rating methodology.
- Linear factors, linked to default probabilities, are also factored in to determine a fund’s credit quality.
How a Weighted Average Credit Rating (WACR) Works
The calculation for WACR varies but generally considers the proportional value of each credit rating as a percentage of the total portfolio. This weighted proportion helps determine the average credit rating, offering deeper understanding of its credit quality.
Special Considerations
WACR is just one of many tools investors use to analyze a fund’s credit quality. Reporting agencies might alternatively use linear factors corresponding to default probability. A linearly adjusted WACR can give a more nuanced view of a fund’s composition by assigning weights to individual rating levels based on default probabilities.
Criticism of Weighted Average Credit Ratings
WACR is not without its detractors. Critics argue that this metric may cause investor confusion, as it might not always accurately reflect the quality of bond holdings. An average rating might indicate categories that do not include any actual bonds from the portfolio, thereby potentially misrepresenting the fund’s health.
Example of a Weighted Average Credit Rating (WACR)
Imagine a bond fund where 25% of its value is rated AAA, 25% BBB, and 50% CCC, resulting in an average rating like B+. This does not offer a precise picture since the fund does not comprise any actual B+ rated bonds. Most bond funds overcome this limitation by presenting weighted rating scales in marketing materials to visualize the concentration of bonds by rating.
For instance, let’s observe the following credit quality dispersion for a hypothetical bond fund:
|————-|———|
| Rating | % |
| U.S. Govt. | 0.3% |
| Aaa | 2.7% |
| Aa | 9.1% |
| A | 37.4% |
| Baa | 50.5% |
| < Baa | 0.0% |
| Total | 100.0% |
This approach offers a clear understanding of the bonds’ ratings distribution, allowing investors to accurately gauge the credit quality spectrum within the fund.
