Today's biggest movers

ARM jumps 8.3% as analyst upgrades pile in after record fiscal year

Arm Holdings PLC (NASDAQ: ARM) surged 8.3% to $412.55, the sharpest single-session gain in our coverage universe and the stock's largest one-day advance since January. The move caps a 97% one-month run and leaves ARM up 260% year to date, extending a multi-year re-rating driven by its royalty exposure to AI inference chips in data centers. Multiple price-target increases preceded Monday's session: Mizuho raised its target to $425 from $360, Barclays to $360 from $250, and KeyBanc to $300 from $170. The upgrades followed ARM's record Q4 fiscal 2026 quarter, in which revenue rose 20% year on year to $1.49 billion, licensing revenue grew 29% to $819 million, and data center royalties more than doubled. Chief Executive Rene Haas told analysts the company's $15 billion in-house chip revenue target could be reached ahead of schedule, citing overwhelming demand from hyperscalers deploying ARM AGI processors in next-generation AI server racks. For context on the two-session build into today, see last Thursday's recap of the agentic CPU upgrade cycle.

AMD gains 7.0% on Citi upgrade citing Meta as undiscounted GPU customer

Advanced Micro Devices Inc. (NASDAQ: AMD) gained 7.0% to $547.26, extending its 2026 year-to-date advance to 145%. Citi analyst Atif Malik upgraded AMD to Buy from Neutral and raised his price target to $575 from $460, pushing his 2026-2028 earnings estimates 12%-13% above Wall Street consensus. Malik's central argument is that Meta Platforms will be a materially larger buyer of AMD's MI-series AI graphics processors than the market is pricing in, a view he said is supported by supply-chain checks. AMD's first-quarter 2026 revenue climbed 38% year on year, driven by its data center division, and the company is next scheduled to report in late July. The stock's intraday high of $558.37 briefly cleared the Citi target before a partial afternoon pullback.

Lam Research rises 6.0% as chip equipment cycle draws fresh price targets

Lam Research Corp. (NASDAQ: LRCX) gained 6.0% to $388.92 as chip equipment stocks caught up with the semiconductor surge. Oppenheimer raised its price target to $400 from $330, and Barclays lifted its target to $335 from $275 in a note issued last Wednesday. Both firms cited the March 2026 quarter, which delivered record revenue and record earnings per share, underpinned by NAND recovery and high-bandwidth memory capacity additions. Lam's June quarter guidance, issued last month, calls for further sequential growth, and Monday's session positioned the stock above Oppenheimer's new target for the first time. The broader chip-equipment complex was lifted by the same Strait of Hormuz tailwind: AMAT added 3.3% and ASML gained 1.6%. For the original BofA upgrade context, see last Wednesday's chip equipment recap.

Palantir adds 5.3% as geopolitical relief lifts defense-adjacent AI names

Palantir Technologies Inc. (NYSE: PLTR) advanced 5.3% to $134.71. The Strait of Hormuz deal was a direct tailwind: Treasury yields fell sharply on the geopolitical relief, and defense-adjacent data analytics companies with government contract exposure rallied alongside energy names. Palantir reported first-quarter 2026 revenue of $1.6 billion, up 85% year on year, and raised its full-year guidance at that result. Despite today's bounce the stock remains down nearly 20% year to date, weighed by the February growth-multiple reset; the current price sits well below the analyst consensus target of approximately $193.

Notable but quieter

Meta Platforms Inc. (NASDAQ: META) gained 4.7% to $593.48. Monday was the ex-dividend date for Meta's inaugural quarterly cash dividend, which tends to draw incremental buying. Truist reiterated a Buy and $840 price target on June 9, calling Meta's AI advertising suite its "next $20 billion business," while UBS carries an even more aggressive $908 target. Meta has guided $125-145 billion in 2026 capital expenditure for AI infrastructure, the largest single-year commitment from any hyperscaler.

Oracle Corp. (NYSE: ORCL) added 4.6% to $192.64, extending a recovery from last week's post-earnings dip. Oracle's Q4 fiscal 2026 results showed cloud revenue growing 47% to $9.91 billion; the company maintained its $90 billion fiscal 2027 revenue target and raised its adjusted earnings-per-share guidance to $8.05 for the current quarter, one cent above analyst consensus.

Taiwan Semiconductor Manufacturing Co. (NYSE: TSM) rose 4.1% to $441.40. TSMC disclosed May 2026 consolidated net revenue of NT$416.98 billion, up 30.1% year on year, confirming that advanced-node utilization for AI chip customers remains at capacity. The 12-month analyst consensus target stands at $468, per 19 sell-side firms.

Nvidia Corp. (NASDAQ: NVDA) gained 3.5% to $212.45 on volume of 130 million shares, second-highest dollar volume in our universe behind only the S&P 500 itself. The company filed last week for its first corporate bond offering in five years, targeting at least $20 billion in proceeds; analysts read the move as a balance-sheet confidence signal rather than a liquidity need. Nvidia's most recent quarterly report showed 85% revenue growth year on year. The annual stockholder meeting is set for June 24.

Salesforce Inc. (NYSE: CRM) was the sole decliner in our 25-name universe, slipping 0.8% to $164.55 on no fresh company-specific news. The stock is down 35% year to date and has shed 6.2% over the past five sessions.

What to watch tomorrow

The Federal Open Market Committee begins its two-day June meeting on Tuesday, with a rate decision and press conference scheduled for Wednesday, June 17. It is the first FOMC session chaired by Kevin Warsh following his confirmation earlier this year. Options markets are pricing a hold at the current target range; any hawkish signal on the pace of future cuts would likely pressure high-multiple AI names that have rerated sharply in 2026. No major AI-sector earnings releases are scheduled this week; the next significant window opens in late July, with AMD and several hyperscalers on the calendar.
