{IMAGERIGHT:http://www.massdevice.com/sites/default/wp-content/uploads/checkup/091020_index1.gif}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 from its most recent quarterly report and each Friday’s closing share price.
The Massachusetts index for the week ended Oct. 16 closed at 4.49, down 9.4 percent compared with the prior week. Since Jan. 1, when we began tracking these companies, the index has risen 1.3 percent.
The Minnesota index for the week ended Oct. 16 closed at 3.33, flat compared with the prior week. Since Jan. 1, when we began tracking these companies, the index has risen 12.8 percent.
