Is BA near its 200-week EMA?
No. BA is 7.4% below its 200-week EMA ($190.47 against $205.64, 1.3 weekly ATRs below) 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 3 times since Aug 2020, most recently in Jul 2026; 13 weeks later price was −7.3% from the level of the touch. The 50-week EMA is $211.58 (price −10.0% from it) and the weekly DeMarker is 0.35, neutral.
What the numbers say
The 200-week EMA itself is up 1.8% over two years, close to flat for a long-term line. Weekly closes have been above the line on 27% of the 324 weeks measured, so price has spent long stretches under it. At its touches the weekly lows went a median 10.8% 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. BA 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 0.35 it is neutral now. This is a long-term, no-leverage way of reading a chart, not a signal to act on.
