S&P Global (SPGI) Stock Analysis & Winston Score
S&P Global is a financial data and analytics company best known for two things: its credit ratings and its market indexes. The credit ratings business grades the financial health of governments and corporations, telling lenders how risky it is to loan them money. The company also owns the S&P 500 index, one of the most widely followed stock market benchmarks in the world, along with Platts (commodity data) and Market Intelligence (financial data tools for professionals). S&P Global earns money through a mix of ratings fees, subscriptions, and licensing — companies pay to have their debt rated, and asset managers pay to license the S&P 500 name for funds and ETFs. It operates globally, with significant revenue from the U.S. and Europe, and its 2022 merger with IHS Markit made it one of the largest financial data providers in the world. Its biggest moat is the near-mandatory nature of its ratings in debt markets, though regulatory scrutiny of the ratings industry remains a persistent risk.
