Qualcomm Drops 6%, Arm Holdings Falls 5% as Mobile-Chip Stocks Slide in the Selloff

Shares of Qualcomm (NASDAQ:QCOM | QCOM Price Prediction) are down 6% to $193 and change in midday trading Wednesday, while Arm Holdings (NASDAQ:ARM) stock is off 5% to $309.75. The moves come as mobile and edge-compute chip names lag the broader semiconductor tape.

The iShares Semiconductor ETF (NASDAQ:SOXX) is down by 2.3% on the session, signaling that the weakness extends well beyond Qualcomm and Arm. QCOM stock and ARM stock are simply at the sharp end of a multi-day chip selloff.

Mobile-Chip Pair Caught in the Downturn

Qualcomm and Arm are tightly linked. Qualcomm’s mobile processors are built on Arm’s instruction-set architecture, and Arm collects royalties across the mobile ecosystem, so weakness in one tends to track the other. The pair also has a history of licensing tension and litigation, which makes their linkage in a selloff worth flagging.

There isn’t one clean catalyst for today’s mobile-chip moves. Traders point to a broad risk-off tone in high-valuation chip names, profit-taking after big year-to-date runs, rate concerns, and the lingering fallout from Broadcom‘s (NASDAQ:AVGO) recent weak AI guidance Broadcom’s recent weak AI guidance.

The macro backdrop isn’t helping. The CBOE Volatility Index or VIX sits at 19.87, up 26% over the past week, and the 10-year Treasury yield is at 4.56%, near the upper end of its 12-month range.

QCOM: A Familiar Air Pocket

Qualcomm’s most recent quarter, Q2 FY2026, beat on both lines with revenue of $10.6B and non-GAAP EPS of $2.65. However, Qualcomm’s handset revenue fell 13% to $6.02B on memory supply constraints and softness from Chinese handset OEMs, a setup that leaves QCOM stock sensitive to any mobile-demand wobble.

The stock carries a forward P/E ratio of 20x and a beta of 1.6, with an analyst target price of $180. Even after today’s pullback, Qualcomm stock is still up 11.6% year to date (YTD), leaving room for further profit-taking.

ARM: High Beta Meets a High Bar

Arm’s most recent quarter showed revenue of $1.49B, up 20% year over year (YoY), with license revenue jumping 29% and data center royalties more than doubling. CEO Rene Haas highlighted the launch of an Arm AGI CPU and over $2B in customer demand across FY27-FY28, with Meta Platforms (NASDAQ:META) as lead partner.

However, ARM stock trades at a trailing P/E ratio of 399x and a forward P/E ratio of 179x, with a beta of 3.8. The analyst target price stands at $247, well below today’s quote, and the stock is still up 181% YTD even after the recent slide.

That valuation profile makes Arm a natural pressure point when risk sentiment turns. ARM stock’s 52-week range of $100 to $428 tells you how much air is in the move both ways.

What to Watch Into the Close

For Qualcomm, the next event on the calendar is the June 24 Investor Day, focused on data center and physical AI updates, which could reframe the narrative beyond handsets. For Arm, traders can track how the stock behaves around its 50-day moving average near $215 if the selloff deepens.

Reddit chatter on QCOM remains in neutral territory with low activity, suggesting retail isn’t capitulating yet. With the VIX elevated and yields firm, investors weighing their exposure to mobile-chip names may want to consider their position sizing and entry points rather than chase intraday lows.

Both the Qualcomm and Arm share-price moves are intraday and can shift in the coming sessions. Any late-day commentary from sector analysts could set the tone into Thursday’s open.
