Winston Score History

The full picture

MBIA Inc. is a financial guaranty insurance company. It promises to pay back investors if bonds they own stop making payments. The main customers are governments, municipalities, and other public entities that issue bonds to raise money for things like roads, schools, and utilities.

MBIA makes money by charging fees and premiums to bond issuers in exchange for wrapping their debt with an insurance guarantee. The company operates primarily in the United States and has a much smaller international business. MBIA was once a dominant player in bond insurance, but it suffered severe losses during the 2008 financial crisis after guaranteeing risky mortgage-backed securities. Today the company is in a long runoff phase, meaning it is no longer writing much new business and is focused on managing and paying down its existing obligations. The biggest risk the company faces is that losses on its remaining insured portfolio exceed the reserves it has set aside to cover them.

Revenue accelerating

MBIA grew revenue 71% year-over-year and the growth rate is speeding up. That's the kind of momentum growth investors look for — the question is whether margins can follow.

The Winston Score above measures business quality today. Growth stocks often score lower because they invest in the future rather than maximising current profits. These metrics show what matters most for evaluating that future.
