In this article, I will feature one medical device company that has seen intensive insider selling during the last 30 days. Intensive insider selling can be defined by the following three criteria:
- The stock was sold by three or more insiders within one month.
- The stock was not purchased by any insiders in the month of intensive selling.
- At least two sellers decreased their holdings by more than 10%.
DexCom (NASDAQ:DXCM) focuses on the design, development, and commercialization of continuous glucose monitoring systems.

Pipeline and upcoming milestones
DexCom is developing and marketing continuous glucose monitoring systems for ambulatory use by people with diabetes and by healthcare providers in the hospital.
DexCom has three pending FDA filings with upcoming approval decisions.
DexCom's competitors include Medtronic (NYSE:MDT). Here is a table comparing these two companies.
DexCom is trading at a higher P/S ratio than Medtronic. In Medtronic, there have been 298,847 shares sold and there have been 4,800 shares purchased by insiders this year. Only DexCom has seen intensive insider selling during the last 30 days.
There have been eight different insiders selling DexCom and there have not been any insiders buying DexCom during the last 30 days. Two of these eight insiders decreased their holdings by more than 10%. DexCom has an insider ownership of 2.00%.
Before entering short DexCom, I would like to get a bearish confirmation from the Point and Figure chart. The three main reasons for the proposed short entry are negative earnings, relatively high P/S ratio, and the intensive insider-selling activity.
