Arm sheds 12.9% as sellers retake control of the week

August 21, 2026

Our view last week

On the daily chart Arm just bounced 5% off its 20-day moving average, in the 275 area, touching the 267 area before climbing back: more indecision than reversal. The Sell signal on Arm stock has been under management for seven weeks, with the short above 11% in profit. On the week the stock gives back just 1.1%, but money flow turns positive and the ADX keeps falling: the decline is losing conviction without flipping yet. Price stays boxed between the 283 area and the 278 area.

This week's summary

After last week's hesitant bounce, Arm's decline came back hard: -12.9% in five days, 96% of volume on the sell side, and a bearish engulfing candle closing out the week. Money flow, which had briefly turned positive, slipped back negative. The short is now more than 22% in profit, but the ADX keeps falling: the trend is dropping without gaining conviction.
