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. MRVL does not meet all three right now: price is more than four weekly ATRs above the 200-week EMA, in a rising long-term trend. The weekly DeMarker adds the momentum read: at 0.59 it is neutral now. This is a long-term, no-leverage way of reading a chart, not a signal to act on.
