Arm’s shares fell 13.08% to $166.72 on Thursday, November 5, as a sharp rise in trading volume and a close at the 20-day low pointed to continued selling pressure. The move was about 1.5 times the stock’s average daily trading range, while volume reached 2.7 times its 20-day average. Oversold momentum indicators suggest the decline has been severe, but they do not yet confirm a reversal.
Trend & Price Action
The fall extended a steep slide: Arm lost 27.12% over five days and 39.44% over one month. Its price is below both the 20-day simple moving average (SMA), at $223.10, and the 50-day SMA, at $254.39. The 20-day average itself fell 10.42% over five days, reinforcing that the weakness is not confined to a single session. No new moving-average crossover was recorded.
At $166.72, the stock closed at its 20-day low and at the bottom of its stated 20-day range. The 20-day support is therefore under immediate pressure; the three-month low of $163.13 is the next reference below it. A break through that longer-period low would mark a further deterioration in price structure, while a bounce would still need to contend with the downward-sloping average and overhead resistance.
As shown in the chart, price sits below the lower Bollinger Band, a position that can accompany intense selling but is not, by itself, evidence that a rebound is imminent.

Momentum & Volatility
The RSI, or Relative Strength Index, is 26.9, in oversold territory. The Stochastic oscillator is also deeply stretched, with %K at 4.8 and %D at 7.2. These readings mean recent losses have been unusually forceful relative to the indicators’ look-back periods. They can precede a pause or rebound, but in a persistent downtrend, oversold conditions can last.
The MACD remains negative: -20.925 versus a -16.644 signal line, with a -4.281 histogram. That configuration indicates downward momentum is still dominant, rather than showing a confirmed turn. The chart brings these signals together: oversold readings are a counterweight to the continuing negative MACD, not a replacement for it.

Volatility is elevated. The 20-day Bollinger Bands have widened to 41.7%, while the stock’s ATR is $14.13, or 8.5% of its price. ATR measures the typical range of price movement; at this level, sizable swings are part of the current setup. The close below the lower band, reflected by %B at -11%, underscores how far price has moved beyond its recent statistical range, but widening bands also signal that volatility is expanding rather than settling.
Participation confirms the severity of the drop. Volume was 15,348,200 shares against a 20-day average of 5,755,485, and on-balance volume (OBV), a measure of whether trading volume is accumulating on rising or falling sessions, declined. The technical screen records two bearish signals: a close below the 20-day low on volume at least 1.5 times average, and a downtrend confirmed by falling OBV. Its overall bias remains neutral, with no bullish signals among the seven assessed.

Key Levels & Scenarios
The immediate test is $166.72 support, with the $163.13 three-month low just below. If price fails to hold that lower reference, the technical picture would weaken further. The data’s ATR-based reference at $145.53 illustrates the potential scale of movement under high volatility; it is a calculated level, not a forecast.
On a recovery, the $187.91 ATR-based level comes before the 20-day average at $223.10. The stated 20-day resistance is $266.28, while the three-month high is $336.98. Those levels provide context for the distance price would need to cover before the broader downtrend could be questioned; a short-term bounce alone would not erase the falling averages or weak OBV.
Fundamental Context
The latest filing shows a mixed earnings picture. According to its SEC filing, Arm reported quarterly revenue of $1.44 billion for the quarter ended September 30, 2026, up 27.1% from $1.14 billion a year earlier. Net income fell to $130.0 million from $238.0 million, while diluted earnings per share were $0.12. Revenue growth points to continued expansion, but the lower profit figure provides a contrasting signal; the technical verdict below is based on price and trading indicators, not those results.

Technical Verdict: HOLD
The neutral technical bias supports a wait-and-see stance: oversold RSI and Stochastic readings raise the possibility of a pause, but negative MACD, falling OBV, and a high-volume close at the 20-day low do not confirm recovery. This verdict is invalidated if price falls below the $163.13 three-month low.
Ideal Entry Range: $163.13–$166.72, using the three-month low and current 20-day support as reference levels.
Exit Target: $187.91, the price-plus-1.5-times-ATR reference.
Stop Loss: $145.53, the price-minus-1.5-times-ATR reference.
For non-traders, the signals are split: the stock is deeply oversold, but selling pressure has not yet clearly eased.
