Qualcomm (QCOM) Stock Tumbles 11.4% as Qualcomm’s AI Rally Cools After Massive Run-Up

Shares of Qualcomm plunged more than 11% Tuesday as semiconductor stocks sold off sharply following hotter-than-expected inflation data and profit-taking across AI-related names.

The decline marked Qualcomm’s worst trading session since 2020 and came after an explosive rally fueled by growing investor optimism around the company’s expansion into AI infrastructure, custom data center chips, and next-generation AI devices.

AI Semiconductor Rally Hits a Pause

The broader semiconductor sector came under heavy pressure Tuesday after inflation accelerated to 3.8% in April, reigniting concerns about interest rates and valuation pressure across growth stocks.

The selloff hit AI-linked chip names particularly hard:

• Intel fell sharply
• Micron Technology dropped
• Marvell Technology declined
• The semiconductor ETF also moved lower

Qualcomm became one of the biggest losers as investors locked in profits after the stock’s enormous rally over the past month.

Markets had increasingly rotated into Qualcomm as investors searched for the “next phase” of AI beneficiaries beyond NVIDIA.

That shift pushed QCOM dramatically higher before Tuesday’s reversal.

Qualcomm’s AI and Data Center Push Remains the Key Story

Despite the pullback, Qualcomm’s longer-term narrative continues strengthening.

The company recently announced a custom silicon agreement with a major hyperscaler, marking a major expansion into data center processors and AI infrastructure.

Investors increasingly view that move as a potentially transformative long-term growth opportunity.

Qualcomm has historically dominated smartphone chipsets and wireless connectivity, but management is now aggressively expanding into:

• AI data center processors
• Custom silicon
• Physical AI devices
• Automotive AI systems
• Edge AI computing
• AI-powered consumer hardware

CEO Cristiano Amon recently said Qualcomm is working with “pretty much all” major AI players on next-generation devices that could eventually evolve beyond smartphones.

That positioning has helped fuel investor enthusiasm around Qualcomm’s role in the emerging “agentic AI” and edge-computing ecosystem.

Strong Fundamentals Continue Supporting QCOM

Fundamentally, Qualcomm remains far stronger than many speculative AI names currently driving the market.

For fiscal Q2 2026, the company reported:

• Revenue of $10.6 billion
• Adjusted EPS of $2.65
• Record automotive revenue of $1.33 billion

The company also authorized a new $20 billion stock repurchase program and raised its quarterly dividend.

Automotive and AI diversification are becoming increasingly important as Qualcomm reduces dependence on the mature smartphone market.

The automotive business, in particular, continues emerging as a major growth driver through connected vehicles, AI cockpit systems, and autonomous driving platforms.

Investor Day and China Developments Remain Important Catalysts

Investors are now closely watching Qualcomm’s June 24 Investor Day, where management is expected to provide additional detail on:

• AI growth strategy
• Data center ambitions
• Hyperscaler partnerships
• Long-term diversification targets
• Capital allocation priorities

Markets are also monitoring geopolitical developments closely.

CEO Cristiano Amon is joining a U.S. business delegation to Beijing alongside President Trump as semiconductor trade policy and U.S.-China technology relations remain major risks for the industry.

Because Qualcomm remains heavily exposed to both the smartphone supply chain and Chinese demand, any improvement or deterioration in trade relations could materially impact investor sentiment.

Technical Analysis: Momentum Remains Bullish Despite Sharp Reversal

Technically, Qualcomm still maintains a strong longer-term uptrend despite Tuesday’s aggressive selloff.

The stock remains well above major moving averages:

• 20-day MA near $163
• 50-day MA near $144
• 200-day MA near $158

That structure continues reflecting strong institutional momentum over recent months.

Key Technical Levels for QCOM Stock

• Immediate resistance: $225
• Major resistance: $237-$240
• Near-term support: $200
• Secondary support: $183
• Major support: $160-$165

Qualcomm’s Valuation Debate Is Becoming More Important

After rallying more than 80% in a month, valuation concerns are increasingly entering the discussion.

Some analysts now argue Qualcomm may be priced ahead of near-term earnings growth, especially as consensus estimates still project modest earnings declines over the next several years.

However, bullish investors believe the market is beginning to price in a much larger AI infrastructure opportunity that extends far beyond smartphones.

That debate will likely determine whether the stock consolidates or resumes its longer-term uptrend.

QCOM’s Long-Term Outlook Still Looks Constructive

Qualcomm’s long-term growth story increasingly revolves around diversification into AI infrastructure, automotive computing, edge AI, and custom silicon.

If the company successfully captures meaningful market share in AI data center processors and physical AI devices, the current valuation could eventually appear more reasonable.

At the same time, risks remain:

• AI competition remains intense
• China exposure creates geopolitical uncertainty
• Smartphone growth remains mature
• Valuation expanded rapidly after the rally

Still, Qualcomm now appears positioned as one of the more diversified AI semiconductor plays in the market.

The latest selloff suggests investors are reassessing valuation and short-term momentum — not necessarily abandoning the broader AI growth thesis surrounding the company.
