Is MRK near its 200-week EMA?
No. MRK is 38.9% above its 200-week EMA ($148.30 against $106.80, 4.9 weekly ATRs above) at the scan of 21 Oct 2026. Weak long-term trend: the 50-week EMA is above the 200-week, but the 200-week EMA has risen less than 8% in two years, so the long-term trend is flat rather than rising. It has touched the 200-week EMA twice since Aug 2020, most recently in Oct 2024; 52 weeks after a touch, price was above the touch level 1 of 2 times, median −0.4%. The 50-week EMA is $124.62 (price +19.0% from it) and the weekly DeMarker is 0.78, neutral.
What the numbers say
The 200-week EMA itself is up 5.2% over two years, close to flat for a long-term line. Weekly closes have been above the line on 84% of the 324 weeks measured. At its touches the weekly lows went a median 4.5% under the line within 13 weeks, and a weekly close fell below it within four weeks on 2 of 2.
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. MRK does not meet all three right now: the 50-week EMA is above the 200-week, but the 200-week EMA has risen less than 8% in two years, so the long-term trend is flat rather than rising. The weekly DeMarker adds the momentum read: at 0.78 it is neutral now. This is a long-term, no-leverage way of reading a chart, not a signal to act on.
