The MassDevice Weekly Checkup: June 29, 2010

June 28, 2010 by MassDevice

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.

The Massachusetts index for the week ended June 25 closed at 5.91, up 0.4 percent compared with the prior week. Since Jan. 1, 2009, when we began tracking these companies, the index has risen 33.3 percent.

The Minnesota index for the week ended June 25 closed at 3.54, down 2.9 percent compared with the prior week. Since Jan. 1, 2009, when we began tracking these companies, the index has risen 20.0 percent.

The California index for the week ended June 25 closed at 8.99, down 3.3 percent compared with the prior week. Since Jan. 1, 2009, when we began tracking these companies, the index has risen 111.7 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):
