The University of Miami’s Florida 50 Index, which was established by the Miami Herbert Business School in 2016, is based on the capitalizations of all Florida-based large-, mid- and small-cap companies included in the S&P 1500 index having common stock listed on the NYSE or NASDAQ. It is the first custom S&P Dow Jones index to be owned by a university, and the only index that focuses solely on public companies headquartered in an individual U.S. state.

“The performance of the Miami Herbert Business School’s Florida 50 Index during the second quarter of 2020 shows that in a market that has rebounded remarkably from the first quarter, Florida-based firms as a cross section are keeping pace with their counterparts from across the country,” said Seth Levine, CPA, accounting lecturer at Miami Herbert Business School and creator of the index.

“The twelve largest companies in the Florida 50 Index have a combined market capitalization of over $300 billion,” he said. “Florida’s Gross Domestic Product (GDP), which surpassed $1 trillion in 2018, rivals that of countries like Spain and Mexico, and thus investors would do well to keep an eye on this index and its diverse set of constituents as they weigh their own investment decisions.”

The index is available under ticker symbol UMIAMIFL. It is calculated by S&P Dow Jones Custom Indices, and its performance can be monitored in real time via Yahoo Finance.
