Arm Holdings Surges 7.85% on Intraday Rally: What’s Fueling the Momentum?

Summary
• Arm Holdings (ARM) rockets 7.85% to $151.86, piercing its 52-week high of $182.88
• Intraday range spans $142.8 (low) to $154.28 (high), signaling aggressive buying
• Options chain sees $750K+ turnover in 140–150 strike calls, hinting at bullish positioning

Arm Holdings is scripting a dramatic intraday rebound, surging 7.85% as traders bet on a breakout. With the stock trading above its 30D, 100D, and 200D moving averages, technical indicators and options flow suggest a short-term bullish tilt. The semiconductor sector, led by AMD’s 1.69% gain, remains in focus as AI-driven demand for chips intensifies.

Bullish Technicals and Options Flow Drive Arm Holdings Higher
The 7.85% intraday surge in Arm Holdings is underpinned by a confluence of technical and options-driven factors. The stock has pierced above its 30D ($139.74) and 200D ($135.69) moving averages, aligning with a short-term bullish Kline pattern. The MACD histogram (0.71) and RSI (59.69) indicate momentum and neutral-to-bullish sentiment. Meanwhile, the options chain reveals heavy call buying in the 140–150 strike range, with the ARM20250919C150 contract seeing $1.28M in turnover. This suggests institutional positioning for a near-term rally, likely tied to AI hardware demand and earnings optimism.

Semiconductor Sector Gains Momentum as Arm Holdings Outpaces AMD
While the semiconductor sector remains in focus, Arm Holdings’ 7.85% surge dwarfs AMD’s 1.69% gain. The sector’s strength stems from AI-driven chip demand, but ARM’s move reflects specific catalysts—namely, its role in enabling next-gen AI architectures. AMD’s modest rise, meanwhile, underscores broader sector rotation rather than a singular breakout. Investors should note that ARM’s options-driven optimism isn’t mirrored in the sector’s broader ETFs, suggesting a stock-specific trade rather than a sector-wide rally.

Options and ETFs to Watch: Capitalizing on ARM’s Bullish Momentum
• MACD: -1.7627 (Signal: -2.4746), RSI: 59.69 (neutral), 200D MA: $135.69 (below price)
• Bollinger Bands: Upper $145.25, Middle $137.89, Lower $130.53 (price above all)
• Key Levels: 200D MA ($135.69) as critical support; 154.28 intraday high as near-term resistance

ARM’s technicals and options flow point to a continuation of the bullish trend. The stock is trading above all major moving averages, with RSI in neutral territory and MACD turning positive. For options traders, the ARM20250919C150 and ARM20250919C149 contracts stand out. The former has a 46.49% implied volatility (IV), 26.25% leverage ratio, and a delta of 0.5887, indicating strong sensitivity to price moves. Its theta (-0.5689) and gamma (0.033264) suggest time decay and responsiveness to volatility. A 5% upside (to $159.45) would yield a payoff of $9.45 per contract. The ARM20250919C149, with 47.06% IV and 23.67% leverage, offers a similar profile, with a projected $14.45 payoff under the same scenario. Both contracts benefit from high turnover ($1.28M and $318K) and liquidity, making them ideal for aggressive bulls.
