Market Rating

Bonds rated from five stars (best) to none. Bonds with lower spreads (less risk) are given more stars than bonds with higher spreads (more risk). Ratings are calculated frequently to ensure they reflect the most current market factors.

Liquidity Rating

Bonds rated from five to none. Computed daily as a ratio based on the number of trades in a given bond compared to the average number of trades of all the bonds in a similar class. The higher the ratio, the more frequently the bond is traded relative to similar bonds.

Fitch Ratings

The Primary Credit Rating Scales (those featuring the symbols 'AAA'–'D' ) are used for debt and financial strength ratings.

Moody’s Ratings

Municipal ratings incorporate Moodyʼs assessment of the default probability and loss severity of these issuers and issues.
