{IMAGERIGHT:http://www.massdevice.com/sites/default/files/checkup/090528_index.jpg}Our Weekly Checkup takes the temperature of the 63 public medical device companies in the MassDevice Index. The index is 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 index for the week ended May 22 closed with a reading of 4.85, up nearly 3.7 percent compared with the prior week. That’s a reversal of last week’s dramatic 18.5 percent decline. Since we began tracking these companies in late March, the index slipped 2.16 percent, mostly due to that precipitous slide during the week ended May 15.
