San Diego-based health care technology firm Dexcom (DXCM) was trending slightly negatively yesterday morning, down 12 cents at 10.50. A similar medical device firm, NuVasive (NUVA) was also slightly down at 16.60.

The Dow Jones Industrial Average (DJI) continues its downward slide after Monday’s 247-point drop. As of Tuesday morning it was down an additional 70 points, around 11,323, caused by Moody’s rating agency mentioning it would review France’s credit rating, and some less-than-stellar earnings from several companies.

The NASDAQ and the S&P 500 were both down a little below 1 percent at 2,590 and 1,192 respectively.

The yield on the 10-year Treasury bond was also down slightly at 2.128 and gold was trading down about 2 percent at 1,642.
