Our Weekly Checkup takes the temperature of the medical device industry’s three largest U.S. clusters: Massachusetts, California and Minnesota.
The MassDevice Indices are weighted according to market capitalization, based on the number of shares outstanding for each company and each Friday’s closing share price.
