Stocks finish October with loss in first monthly decline since April

The S&P 500 slid 1.9% on Thursday, its worst daily loss since early September. The tech-heavy Nasdaq 100 fell 2.4%. The Russell 2000 was down 1.6%. Major indexes all edged down this month, and the benchmark S&P 500 broke a five-month-long monthly winning streak.  

Stocks were sent lower by declines in megacaps amid busy earnings. All Magnificent 7 stocks slid. Microsoft was down 6% and Meta fell 4.1%; both delivered upbeat earnings, but Microsoft forecasted slower cloud-revenue growth, while Meta said that its capital expenditures would grow as it scales up AI investments. Amazon and Apple, which reported after the closing bell, slumped 3.4% and 2%, respectively, ahead of their releases. Nvidia, which won’t report until November, tanked 4.7%. 

Most other sectors retreated as well. However, the utilities sector ETF rose 1%, thanks to Entergy, which climbed 15.2% and hit an all-time high after earnings beat. 

In other individual stock moves, shares of Peloton climbed 27.8% on strong earnings and a new CEO. Roblox  jumped 19.9%, as results for both bookings and earnings per share beat expectations. Beauty conglomerate Estée Lauder lost a whopping 20.9%, its biggest one-day drop in history, after management slashed the dividend and withdrew their 2025 outlook. 

The 10-year Treasury yields had its biggest monthly gain in over two years to hit 4.28%. Gold retreated. Crude-oil futures settled higher on Thursday following reports that Iran may be planning an attack on Israel, finishing the month with gains.

Roblox rallies on a Jefferies price target hike and positive sentiments from Morgan Stanley

Gaming platform Roblox is in the green on Tuesday, following a price target hike from Jefferies to $130 from $126. That target is about 5% below where Roblox is currently trading.

Meanwhile, Morgan Stanley maintained its higher $170 target on the company — one of gaming’s biggest “black holes.” Morgan Stanley called Roblox a clear leader in next-gen entertainment, with parallels to YouTube given its strong position in user-generated content.

In recent months, Roblox has seen booming player counts through updates and events in its most popular titles, including “Grow a Garden” and “Steal a Brainrot.” According to third-party tracking firm RoMonitor, “Steal a Brainrot” had more than 25 million concurrent players on Saturday, when a Halloween update was added to the game.

Data center stocks knocked back amid China stress

The buy-everything-data-center-related trade is having a rough ride Tuesday, with Goldman Sachs’ themed basket of AI data center stocks dropping 1.5% in early trading after soaring more than 3.5% to start the week.

That’s partially because some suppliers of bits and bobs needed to fit out the hangar-like concrete structures selling computing power for AI are still exposed to risks of the China-US trade war, which seems to be flaring anew.

For instance, while most of the switches and routers Arista Networks sells are made in Malaysia, Vietnam, and Mexico, it also gets some products directly from China. The company is also reliant on supplies of some critical metals, exports of which China is clamping down on.

Such actions, the company has previously warned, could lead to disruptions to supplies of components it needs, manufacturing delays, and inventory shortages.

Other related stocks slumped in early trading, including hard disk data storage makers Seagate Technology Holdings and Western Digital — also exposed to Asian supply chains — and server maker Dell.

Chip giants Nvidia and Broadcom were also down more than 3% each after Advanced Micro Devices announced a new deal to deploy its chips in Oracle data centers.

While previous announcements to that effect lifted the AI sector as a whole, the AMD deal wasn’t enough offset the pall cast by the renewed China stress.

OpenAI to offer Walmart products for sale through ChatGPT

Walmart is partnering with OpenAI to enable shoppers to purchase products directly through ChatGPT, an executive for the retail giant told Bloomberg.

Soon, ChatGPT users will be able to look up Walmart products (minus fresh foods) and simply click “buy.” OpenAI previously announced similar partnerships with Etsy and Shopify last month.

AMD jumps after reaching deal to deploy 50,000 AI chips in data centers run by Oracle

Advanced Micro Devices is jumping (again) in premarket trading after Oracle said it will deploy 50,000 AMD AI chips in its data centers starting in the second half of 2026.

Financial terms of the agreement were not disclosed.

One could say AMD’s pact with OpenAI that was announced last week is already paying dividends: AMD securing OpenAI as a customer, which itself is responsible for Oracle’s massive backlog in cloud computing capacity, means Oracle is now more comfortable using AMD as a source of AI chips.

Or, given the very peculiar terms of that AMD-OpenAI agreement, a cynic might suggest it’s yet another example of circular deals in the AI space, and that both AMD announcements may be about the same thing!

Today’s revelation didn’t spark any additional move lower for Nvidia, which has been trading in the red ahead of the open.
