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 May 21 closed at 5.70,
up 40.2 percent compared with the prior week. Since Jan. 1, 2009,
when we began tracking these companies, the index has risen 28.7
percent.
The Minnesota index for the week ended May 21 closed at 3.66, down
3.8 percent compared with the prior week. Since Jan. 1, 2009, when
we began tracking these companies, the index has risen 24.0
percent.
The California index for the week ended May 21 closed at 9.29, down
2.9 percent compared with the prior week. Since Jan. 1, 2009, when
we began tracking these companies, the index has risen 119.0
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):
The Weekly Checkup also compares Monday
