S&P 500 falls even with most stocks rising as traders dump AI names

The S&P 500 fell 0.6% despite having far more gainers than losers.

8/19/25 3:31PM

The nascent pullback across high-flying, AI-linked names picked up steam on Tuesday, sending major indexes down even as most stocks went up.

The S&P 500 fell 0.6% despite having far more gainers than losers, the Nasdaq 100 tumbled 1.4%, and the Russell 2000 gave back 0.8%.

The iShares MSCI USA Momentum Factor ETF had its worst day since the opening session of Q3, with Palantir leading S&P decliners. The AI darling fell 9.3% to match its longest losing streak since April 2024.

As you’d expect given the tape, with indexes down despite most stocks rising, the pain at the S&P 500 sector ETF level was concentrated in tech — communication services and consumer discretionary were the only other two sectors to fall on Tuesday. Morgan Stanley’s basket of AI tech beneficiaries suffered its biggest one-day drop since April 10, falling 4.1%.

Gains on the day were led by Intel, which rose 6.9% after the company reported that Japanese tech giant SoftBank Group was buying a $2 billion stake in the US chipmaker. Elsewhere...

Home Depot shares were up 3.2% after the home improvement retailer turned in weaker-than-expected Q2 results but doubled down on its full-year outlook.

Best Buy shares were up 3.3% after the electronics retailer announced plans to launch a new third-party marketplace, expanding its online assortment beyond tech.

Palo Alto Networks was a rare sight on Tuesday: an AI-linked name that performed well. Shares jumped 3% after posting top- and bottom-line beats in the fourth quarter along with a bright outlook for its current fiscal year.

Meta shares were down about 2% as the tech giant announced internally that it’s splitting its AI division. The decisions reportedly include moving employees, AI executive exits, and eliminating some roles.

Fabrinet shares sank 12.8% after the maker of optical communication devices said that sales in its data communication business are expected to fall in the current quarter.

Viking Therapeutics fell 42% after the company reported trial results for its weight-loss pill Tuesday morning that disappointed investors.

Retail darling Planet Labs soars on earnings pop for second straight quarter

Planet Labs, which operates a network of satellites that record data, images, and information about the Earth, surged more than 40% after reporting better-than-expected quarterly numbers before the open of trading Monday.

It was the second straight quarter when the money-losing company’s quarterly update generated a massive market reaction. The stock jumped nearly 50% after numbers came out in June.

The company, which went public via SPAC in 2021, raised its full-year revenue guidance and notched its second straight quarter of positive free cash flow. Analysts and investors watch free cash flow closely as it can signal when a company’s business is starting to become more durable.

While the company is small — roughly $2.5 billion in market cap — it has posted pretty serious gains, rising almost 300% the past 12 months. Planet Labs also appears to have a fairly large retail shareholder base.

Just 57% of its float is in the the hands of institutional investors, according to FactSet data. That’s roughly the same as other retail favorites such as Palantir, though Planet Labs is no where near as highly valued as the defense data and AI software company led by CEO Alex Karp.

OpenAI’s cash burn suggests selling Nvidia because of reported Broadcom chip orders may not make much sense

When Broadcom announced that it booked $10 billion in new orders from a customer reported to be OpenAI, shares of their major AI chip rivals tanked.

The judgement of the Invisible Hand was that this was nearly a zero-sum outcome: $130 billion of market cap erased from Nvidia and Advanced Micro Devices, and a $135 billion increase in Broadcom’s market value.

But looking at this from the perspective of near-term cash flows, the market’s view seems off.

The Information is reporting that OpenAI now expects to burn through $115 billion by the end of 2029 (or more than 11 seasons’ worth of NFL broadcasting rights).

Let’s zoom in on this tidbit from The Information:

But the biggest change emerging from OpenAI’s latest projections was to its cash flows. The company projected it will burn more than $8 billion this year, or roughly $1.5 billion higher than its prior projection from earlier this year. Cash burn will more than double to more than $17 billion next year—$10 billion higher than what the company earlier projected

That $10 billion fits all too neatly with the $10 billion in orders from a major new customer that Broadcom CEO Hock Tan pointed to in the chip designer’s earnings call.

(Cheers to @lokoyacap for flagging this on X)

Assuming the reporting around OpenAI and Broadcom is accurate, these orders for ASICs don’t look to be displacing what the ChatGPT creator was going to spend on Nvidia’s GPUs, but are just in addition to it! The money’s not coming out of Jensen Huang’s pockets, it’s coming out of OpenAI’s coffers. Their spending budget is just getting bigger.

Perhaps if you squint, there’s a world in which OpenAI may prefer to have an additional $10 billion in Nvidia GPUs rather than ASICs, and I am still of the belief that hyperscalers diversifying their chip sources due to constrained top-end supplies isn’t a good sign for the company selling the most in-demand product.

But it’s quite intriguing, and says something about the depth of the pockets that fuel the AI boom, that OpenAI’s reported new relationship with Broadcom has seemingly no direct negative financial impact on Nvidia in the near term.

Broadcom’s post-earnings romp continues on heavy volumes

As Broadcom enjoys a rush of new orders from a major new customer (reported to be OpenAI), it’s also reveling in a flood of traffic into the stock.

Volumes are running at 2.5 times their daily average through 1:20 p.m. ET as traders continue to bid up shares in response to the brighter outlook for 2026 revenues, which sent the stock up 9.4% on Friday.

The chip designer is basking in a flood of price target hikes from Wall Street, with Bank of America, JPMorgan, Argus Research, Citigroup, Bernstein, Deutsche Bank, Morgan Stanley, Barclays, Piper Sandler, Rosenblatt Securities, Wells Fargo, and Susquehanna upping their view on how high shares can go since the company reported earnings last week.

Separately, Taiwanese industry outlet DigiTimes is reporting that orders from several other leading tech companies for custom-made Broadcom chips (or ASICs) are “already in the pipeline.” This report has not been corroborated by our own or any other publication’s reporting to date.

SpaceX spectrum deal sends would-be rivals lower

Shares of struggling satellite services company EchoStar soared Monday, after the company — which had recently tottered close to bankruptcy — announced the sale of some of its wireless spectrum licenses to Tesla CEO Elon Musk’s SpaceX for $17 million.

The sale provides a competitive advantage to Musk’s growing Starlink satellite services business, as the licenses it is acquiring from Echostar allows Starlink to operate ground based broadband and cellphone services, the Wall Street Journal reported.

Entities that stood to be hurt by the emergence of a Musk-led SpaceX Starlink service got hit hard on the news. AST SpaceMobile, which has plans to offer a similar satellite-to-consumer cellular service, tumbled.

So did wireless tower providers like Crown Castle and American Tower. Low cost cellular service provider T-Mobile, which had a deal with SpaceX, also slumped, as Luke noted earlier, along with other large wireless telecommunication services providers.

The wireless telecommunications industry grouping within the S&P 500 was down more than 2.5% shortly after noon, making it the worst performing industry within the S&P 500 on Monday.
