Why Chip Stocks Went on a Wild Ride in June — and Why Nvidia Keeps Stalling at $5 Trillion

June has been a rough month for U.S. semiconductors. In less than two weeks, chip stocks shed more than $1 trillion in market cap, staged a sharp comeback to open this week, then gave back much of those gains. Nvidia (NVDA) — the sector's bellwether — has been grinding in a tight range around the $5 trillion mark the whole time.^{[Intellectia]}

The volatility reflects a mix of industry-specific concerns and broader macro unease over interest rates.

Early June: A $1 Trillion-Plus Wipeout

The sector's rough patch started with a punishing selloff earlier this month. At its worst, Nvidia dropped roughly 6% in a single session and briefly fell below $5 trillion in market cap; Micron (MU), AMD, and Qualcomm (QCOM) each fell more than 9% at their lows. All told, the selloff erased more than $1 trillion in combined sector value.^{[Yahoo Finance]}

Several catalysts were cited across media coverage:

• Broadcom's (AVGO) soft AI chip guidance: Broadcom guided Q3 AI chip revenue to roughly $16 billion, missing analyst expectations of $17.2 billion, and left its full-year AI semiconductor outlook unchanged.
• Memory market pressure: Stress in the memory chip market continued to weigh on sentiment.
• Smartphone demand warning: Research firm IDC warned that 2026 could see the largest annual decline in global smartphone shipments on record, with volumes expected to fall 13%.^[Kavout]

Week Open: Chips Bounce Back Hard

Stocks came roaring back to start the week. Intel (INTC) led the charge with an 11.19% gain; Micron jumped 9.87% and Nvidia added 1.73%. Applied Materials (AMAT) rose 8.64% and ASML climbed 6.54%.^{[Intellectia]}

The rally proved short-lived, however. Nvidia, Broadcom, Micron, and AMD subsequently retreated, with profit-taking widely cited as momentum stalled.^{[Yahoo Finance]}

Rally Fades: Profit-Taking Meets a Hawkish Fed

Rate anxiety added another headwind. April CPI came in at 3.8% YoY — above expectations — leading markets to reprice for a "higher for longer" Fed. The Fed's hawkish economic projections following its June 17 meeting compounded the pressure on high-multiple growth names.^[HeyGoTrade]

Chip stocks, which tend to carry lofty valuations, are particularly rate-sensitive: when Treasury yields rise and the market prices in fewer cuts, those multiples face compression — a dynamic that has amplified the sector's mid-month swings.^{[Intellectia]}

Nvidia Stalls at the $5 Trillion Mark

After the early selloff and this week's partial recovery, Nvidia is back to trading around $5 trillion. Multiple data sources put its market cap at roughly $5.0–5.08 trillion as of mid-June, still among the highest of any company in the world; minor discrepancies across sources reflect different snapshot times.^{[Companies Market Cap]}

What to Watch

• Treasury yields: Any further move higher in the 10-year puts additional pressure on chip stock valuations.
• AI capex signals: Guidance from hyperscalers and chip companies on AI spending remains the key demand indicator.
• Memory and smartphone trends: Memory chip pricing and global handset shipment data will determine how quickly sector fundamentals can stabilize.
