These are the stocks posting the largest moves in midday trading.

The pastor of Pattison United Methodist Church recently saved a member of her congregation who was in the middle of a diabetic emergency.

Dexcom's technology chief admits that the maker of continuous blood sugar monitoring systems was caught flat-footed by a technology outage over the Thanksgiving holiday weekend, and was ill-equipped to properly inform users of the problem. Because of a server glitch, a large number of Dexcom's customers, who rely on the company's technology to manage their diabetes treatment, weren't alerted to potentially dangerous changes in their blood glucose levels. The issue was of particular concern to parents who use Dexcom's system to monitor their kids' health. "It was a complete surprise," said Jake Leach, Dexcom's chief technology officer, in an interview late Monday, after CNBC published a story on the ongoing problem. Leach said that over the weekend, Dexcom pulled in its internal engineers to work on restoring the system and recruited help from its technology infrastructure partners.

Dexcom's continuous blood sugar monitors are designed to make it easier for patients with diabetes to get frequent readings without the finger prick system. But since Saturday, a glitch in Dexcom's technology has kept patients and parents of kids with diabetes from getting regular updates, leaving them unaware of potentially dangerous problems. However, we have determined that a server overload occurred due to an unexpected system issue that generated a massive backlog, which our system was unable to sufficiently handle." Patients use trackers to monitor their blood sugar levels so they know what their body needs, whether it's more sugar or an insulin injection. Over the holiday weekend, many parents took to social media to describe the anxiety they experienced from the glitch that kept them from getting alerted overnight if their child's blood sugar levels dropped too low.

As the U.S.-China trade dispute rolls on and the political storm clouds continue to swirl, there are some stocks that all investors must have in their portfolio, according to Wall Street analysts. CNBC looked through the most recent Wall Street research to find stocks that analysts say are a "must own" for clients. Dexcom also said it expects to unveil its latest glucose monitor model called G7 in late 2020 and analysts are intrigued. The company provides spa services to cruise ships and global destination resorts and also recently held investor meetings for analysts. Here's what analysts say are "must own" stocks:

Some patients also don't have access to monitoring tools that show how lifestyle choices, like food and exercise, can impact them. As a result, tech giants Alphabet, Amazon and Apple are all exploring how they can bring new services and tools to market to help people with diabetes better manage their disease. Apple is working closely with medical device makers like Dexcom to build integrations with consumer devices like Apple Watch and iPhone. In an interview, Verily's chief medical officer Jessica Mega noted that Alphabet has been focused on diabetes for years. And it's got a partnership with Dexcom to make a new continuous glucose monitoring device that is targeted to people with type 2 diabetes.
