Taking the financial temperature of the medical devices industry

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.

MassDevice index Massachusetts
The Massachusetts index for the week ended May 28 closed at 5.84, up 2.5 percent compared with the prior week. Since Jan. 1, 2009, when we began tracking these companies, the index has risen 31.9 percent.

MassDevice index Minnesota
The Minnesota index for the week ended May 28 closed at 3.88, up 31.3 percent compared with the prior week. Since Jan. 1, 2009, when we began tracking these companies, the index has risen 5.9 percent.

MassDevice index California
The California index for the week ended May 28 closed at 8.67, down 6.7 percent compared with the prior week. Since Jan. 1, 2009, when we began tracking these companies, the index has risen 104.3 percent.

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):
