Arm Holdings plc shares dropped 7.41% to $246.60 on Tuesday as investors pulled back from high-growth technology stocks amid renewed caution in the AI supply chain. The decline followed losses in key memory makers SK hynix Inc and Micron Technology Inc, which fell 8%-9%, sparking debate over whether memory producers are capturing too much of the AI economics and if hyperscalers will sustain capital spending. While S&P 500 futures rose 0.34%, Nasdaq futures slipped 0.76%, reflecting broad pressure on high-multiple names despite Arm’s longer-term growth trajectory.

The selloff was exacerbated by weakness in South Korean markets, driven by concerns about AI infrastructure demand and Chinese competition. This broader risk-off sentiment in the semiconductor sector has intensified scrutiny on crowded positions in AI-related equities. Arm’s stock movement underscores the volatility inherent in the current AI infrastructure cycle, where sentiment shifts rapidly based on spending signals from major cloud providers.

Technical Analysis

Arm remains under pressure in the short term, trading 16.3% below its 20-day simple moving average (SMA) of $293.32 and 24.1% below its 50-day SMA of $323.51. These metrics indicate that the intermediate trend has weakened significantly. However, the stock retains a constructive long-term outlook, sitting 30.1% above its 200-day SMA of $188.84 and just 0.4% above its 100-day SMA of $244.77. The proximity to the 100-day SMA suggests this level acts as a critical support zone.
