At its touches the weekly lows went a median 12.8% under the line within 13 weeks, and a weekly close fell below it within four weeks on 2 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. WDC does not meet all three right now: price is between one and four weekly ATRs above the 200-week EMA, in a rising long-term trend. The weekly DeMarker adds the momentum read: at 0.26 it is neutral now. This is a long-term, no-leverage way of reading a chart, not a signal to act on.
