Sandisk jumps on S&P 500 inclusion announcement

Sandisk was up as much as 6% in premarket trading after S&P Global announced that the flash memory card maker will join the S&P 500 Index on November 28, 2025, replacing advertising giant Interpublic Group, which is being acquired by Omnicom.

Sandisk’s inclusion comes nine months after it was spun off from its parent company, data storage giant Western Digital. Since listing on the Nasdaq, the stock has been on a tear, with its shares soaring more than 500% this year, pushing its market cap to ~$33 billion. That’s more than double what Western Digital originally paid for the company when it bought Sandisk back in 2016 for roughly $16 billion in a bid to expand into flash memory chips, as its traditional hard disk drive business faced mounting pressure.

The company sells high-speed flash memory for consumer electronics like phones and cameras, and is pushing deeper into the data center supply chain. Its latest quarterly earnings showed strong momentum, with a 23% year-over-year increase in sales and solid guidance that topped Wall Street estimates.

Sandisk’s addition follows a broader move of tech firms joining the S&P 500 this year, including AppLovin, Robinhood, Datadog, Block, and DoorDash. 

The stock pop this morning reflects the classic S&P 500 inclusion effect — a temporary rise that occurs when a stock is added to America’s flagship index, tracked by $13 trillion in passive funds and ETFs that are required to buy newly included stocks. Indeed, that effect is back in force this year, after losing steam for much of the last decade.

Report: Boeing could unveil 500-jet order from China during Trump’s visit later this month

Shares of Boeing are up nearly 4% on Friday afternoon, following a Bloomberg report that the company could be close to finalizing a deal to sell 500 planes to China.

The deal was first reported in August and would be one of Boeing’s largest ever.

According to Bloomberg’s sources, the deal could be officially unveiled when President Trump travels to China at the end of the month. That trip could be delayed given the war in Iran. The deal, sources say, could still fall apart — similar language to when it was first reported on more than six months ago.

Boeing has been on the outside of the Chinese market, in terms of new orders, since 2019 amid escalating US-China trade tensions.

Why software shares are withstanding the war jitters

The outbreak of the war in Iran has clearly rattled investors and created a few clear winners — mostly energy stocks — and losers — consumer staples, airlines, and, well, more or else everything else.

But there is one interesting outlier to that Manichaean market dynamic.

Software shares — often the same companies that the market was giving up for dead just a few weeks ago due to overexpectations of an AI-driven disruption — have been holding up remarkably well.

These companies, including Intuit, ServiceNow, Datadog, Snowflake, IBM, Workday, and Oracle, have actually had a pretty decent run since the war started with a combined US-Israeli attack on Iran last weekend.

A new note from RBC Capital’s Rishi Jaluria suggests this isn’t just a fluke. Looking at the performance of software stocks during periods of geopolitical stress and market volatility over the last 10 and 25 years, his team found that software shares appear fairly well insulated when these broader shocks hit. RBC wrote:

“The defensive nature of SaaS models and the mission-critical nature of many core software systems at the enterprise level (e.g., in the absence of mass layoffs that may create seat-based headwinds, geopolitical uncertainty and/or market volatility typically will not cause an enterprise CIO to consider ripping out their ERP, CRM, Cyber systems, etc.”

I briefly got Jaluria on the phone yesterday, and he explained a bit more about why he thinks investors might see software as a decent place to hide out from the current chaos.

“With everything in the Middle East, you have to think about not just oil and gas input prices but also supply chains,” he said. “With software, you’re not really thinking about that.”

In other words, there is no equivalent of a closure of the Strait of Hormuz that software investors have to worry about.

Others suggested that the near-term profitability of these giant software companies — aside from concerns about potential long-term disruption from AI — may look different in the face of the economic uncertainty that seems to be growing with the war, especially after a sell-off that has left them relatively attractively valued.

Mark Moerdler, who covers software stocks for Bernstein Research, says that while the AI worries are clearly real, software companies continue to be highly productive cash cows.

“Everyone is afraid that AI is a massive disruptor, and all these articles you read talk about AI as massive disruptor or the world is ending or whatever,” he said. “You don’t see it in the fundamental numbers of the companies I cover. They are delivering GAAP profits, free cash flow, and they’re good investment ideas.”
