Meta (META) Jumps as Muse, Its First Paid Personal AI Agent, Puts a Price on AI
Meta rose about 6% to roughly $650 on September 9 after launching Muse, a personal AI agent — and, crucially, attaching a price to it: a free tier plus subscriptions at $20 and $100 a month. For a company that has spent enormous sums building AI infrastructure with little consumer revenue to show for it, Muse is a major new consumer-AI monetization line — its first paid personal-agent product — the proof of concept investors had been waiting for. Muse is an autonomous assistant that reads email, books travel, negotiates, and makes purchases through connected payment systems, rolling out in the US on iOS, Android and the web. The launch also rippled across the mega-caps: Alphabet fell ~2.6% as a capable buying-and-booking agent was read as a competitive threat to Google's search (Amazon also slipped ~2.1%, though it had its own news that day). The context is that Meta had lagged — down ~13% over the past year on AI-cost fears — despite an 82% gross margin, ~28% revenue growth and ~$41 billion of free cash flow, at just 19 times forward earnings. Muse does not resolve the spend-versus-return debate, but it reframes it, and the Street stays overwhelmingly bullish, with an average target implying ~16% upside.

Amgen (AMGN) Falls as a Rival's Lp(a) Trial Failure Clouds Its Pipeline
Amgen fell about 8% to roughly $404 on September 8 even as it posted its own good news that morning — its cancer drug IMDELLTRA, with AstraZeneca's Imfinzi, hit its primary survival goal in a Phase III lung-cancer study. The shares dropped anyway, on a rival's failure: Novartis disclosed late last week that pelacarsen — its drug for lowering lipoprotein(a), or Lp(a), a genetic cardiovascular risk factor — failed the primary goal of its large Phase III outcomes trial, not reducing heart attacks, strokes and cardiovascular deaths despite lowering Lp(a). Because Amgen is racing in the same class with its own experimental drug, olpasiran, the read-through was direct: the first dedicated Phase III cardiovascular-outcomes readout of an Lp(a) therapy came up empty, casting doubt on the science behind the category. A separate same-day BMO Capital downgrade — on valuation and pipeline grounds — formed part of the negative backdrop. What cushioned the fall is that Amgen is a cheap, cash-rich defensive franchise — about 18 times forward earnings, a 2.5% dividend, ~$10 billion of free cash flow — so the Lp(a) opportunity was upside, not the foundation. Even so, the stock had run up ~43% over the year, and the Street was already cautious, with a large share of analysts at Hold and an average target below the pre-drop price.

Intel (INTC) Jumps on a High-NA EUV Milestone, Ahead of TSMC in Deployment
Intel rose about 8% to roughly $103 on September 8 after it and lithography partner ASML announced they have processed more than one million wafers using High-NA EUV — the newest, most advanced chipmaking lithography, by industry accounts more than any rival has run. Intel is deploying the technology on select layers of certain 18A products (chips such as Panther Lake), and reports throughput and yields meeting expectations, giving it a multi-year lead in High-NA production experience — TSMC is generally expected to bring High-NA into high-volume production around 2030, and Samsung targets it for DRAM around 2028. The milestone was the headline, though the stock also had a same-day analyst upgrade and reports of possible processor price increases. For a company whose whole case rests on rebuilding a credible foundry business, it was tangible proof the turnaround is producing real capability. The move caps a staggering ~322% one-year run — yet the fundamentals lag: Intel is still GAAP-unprofitable, and the Street stays cautious, with a Hold consensus (roughly two-thirds of covering analysts on the sidelines) and an average target only about 12% above the price. One firm (Northland) upgraded to Buy on the news; most are waiting for the manufacturing lead to become profit.

Snowflake (SNOW) Jumps 16% on a Q2 Beat-and-Raise as a Software Pop Fades
Snowflake jumped as much as 26% intraday to a 52-week high of $384.56, then pared the gain to close up about 16.5% at $356.47, after reporting fiscal second-quarter results the evening before that beat and — the part that moves stocks — raised full-year guidance. Product revenue re-accelerated to about 37% growth ($1.49 billion), adjusted earnings of about $0.62 topped the ~$0.45 expected, and management lifted its full-year product-revenue target to roughly $6.07 billion while widening its margin outlook. The beat-and-raise sparked a sympathy surge across software — Datadog and MongoDB edged higher — on the idea that AI is a tailwind rather than a threat, but that broader enthusiasm largely faded by the close, leaving both peers up only about 2.5% while Snowflake held its gain. The catch is the price: after a ~55% year, Snowflake trades near 15 times forward sales and is still GAAP-unprofitable on heavy stock comp, though it closed somewhat below the average analyst target even after a wave of same-day target increases.

Apple (AAPL) Rises as Ternus Takes Over and the Sept. 9 iPhone Event Nears
Apple rose about 2.5% to roughly $325 on September 1, and the striking part was the company it kept: on a risk-off day driven by rising Treasury yields, Apple was one of the very few large-caps to rise — Meta also gained — while Microsoft, Nvidia and Alphabet slipped alongside the Nasdaq-100. The day carried two milestones. A long-planned leadership handover took effect: John Ternus, the hardware engineer behind the iPhone and Vision Pro, became CEO, with Tim Cook — chief executive since 2011 — moving to executive chairman; the succession was announced back in April, so this was the orderly handover, not fresh news. And Apple's September 9 event, expected to unveil the iPhone 18 Pro and a first foldable, is days away. The catch is valuation: at about 36 times earnings, after a ~40% run, the stock sits right at its average analyst target and about 6% below its late-July record — and the Street is split, with a Bernstein $370 bull case against a rare Jefferies bearish call (an Underperform near $264).

Deere (DE) Hits a Record High After a Baird Upgrade on a 2027 Ag Recovery
Deere rose about 2.6% to a record high near $676 on September 1, standing out on a day technology and semiconductors sold off. The catalyst was dated and company-specific: a day earlier, Baird's Mircea Dobre upgraded Deere to Outperform and raised his price target to $800 from $640, arguing North American crop economics improve in 2027 — corn back above breakeven, better soybean margins, tighter stocks-to-use. Baird upgraded AGCO the same day, and both farm-equipment makers rose while construction bellwether Caterpillar fell, isolating an agriculture-specific move rather than a broad machinery rally. The puzzle is the valuation: Deere trades at about 36 times trailing earnings, but that reflects an expected fiscal-2026 revenue trough (down ~10% on consensus estimates), with fiscal-2027 modeled up ~8% — the recovery the upgrade is betting on. The catch: after a ~40% run to a record, the Street is split, with 11 of 24 analysts at Hold and an average target just below the price.
