Is DXCM near its 200-week EMA?
Yes. DXCM is 2.8% above its 200-week EMA ($85.74 against $83.41, 0.4 weekly ATRs above) at the scan of 21 Oct 2026. Long-term downtrend structure: the 50-week EMA is below the 200-week EMA, so the weekly structure is bearish and the 200-week zone does not apply. It has touched the 200-week EMA 3 times since Aug 2020, most recently in Jul 2024; 52 weeks after a touch, price was above the touch level 1 of 3 times, median −13.2%. The 50-week EMA is $77.31 (price +10.9% from it) and the weekly DeMarker is 0.64, neutral.
What the numbers say
The 200-week EMA itself is down 15.4% over two years, a falling long-term line. Weekly closes have been above the line on 62% of the 324 weeks measured. At its touches the weekly lows went a median 21.0% under the line within 13 weeks, and a weekly close fell below it within four weeks on 3 of 3.
Every touch of the 200-week EMA since Aug 2020
From 324 weeks of weekly bars. A touch is a week whose low reached the 200-week EMA after 13 weeks above it. Each row shows how deep the lows went in the 13 weeks after, whether a weekly close fell below the line within four weeks, and where price closed 13 and 52 weeks later, against the EMA at the touch.

How to read the 200-week zone
The Desk's Portfolio Builder reads three things together: the 50-week EMA above the 200-week, the 200-week EMA rising at least 8% over two years, and price within one weekly ATR of the 200-week line. DXCM does not meet all three right now: the 50-week EMA is below the 200-week EMA, so the weekly structure is bearish and the 200-week zone does not apply. The weekly DeMarker adds the momentum read: at 0.64 it is neutral now. This is a long-term, no-leverage way of reading a chart, not a signal to act on.
