{IMAGERIGHT:http://www.massdevice.com/sites/default/wp-content/uploads/checkup/090804_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 July 31 closed at 4.79, down 3.6 percent compared with the prior week. Since Jan. 1, when we began tracking these companies, the index has risen 8.2 percent.
The Minnesota index for the week ended July 31 closed at 3.39, flat compared with the prior week and up 14.8 percent since Jan. 1.

We also create a composite index of the three regional indices and compare it with four other indices (the S&P 500, the Dow Jones Industrial Average, the Dow’s IHI medical devices index and the NASDAQ exchange):
