📊 SanDisk Faces Off Between a Credit Rating Upgrade and CXMT Pressure - 2026.10.16

Hi, it’s Peanut. I’m back with the numbers first today, too. SanDisk’s stock has been swinging around lately, and amid all that, news broke that S&P raised its credit rating to BBB ^[1]. Sounds like good news, right? Is it really? Let’s check the numbers together.

📉 Why does the stock keep sliding?

Looking at recent closes, the moves were fairly steep: $1,487.33(-5.97%) on October 12 and $1,403.34(-5.33%) on the 14th. The closing price on the 15th was $1,396.70, with a change of -0.47%. Barron's reported that SanDisk and AMD shares fell during this period, with AI concerns related to Anthropic adding to the pressure ^[4]. This looks less like a story about industry conditions and more like a market swayed by AI sentiment. Sentiment can turn quickly, so we need to look at it alongside the numbers.

🔍 How real is the CXMT pressure?

Yahoo Finance covered SanDisk facing fresh pressure from CXMT ^[2]. But an analyst at Investing.com listed 7 reasons why CXMT's claims don't threaten Micron and SanDisk ^[3]. The fact that a list of 7 counterarguments emerged also suggests the market is paying close attention. Peanut tends to get more skeptical when the rebuttal gets longer. Is it really so? Whether those 7 points translate into actual earnings figures has yet to be verified. It’s best to treat them as the analyst’s claims for now.

⚠️ The credit rating upgrade—and the questions that remain

The headline on the S&P upgrade says AI memory demand boosted cash flow by more than $23B ^[1]. However, that’s based on the headline, so we need to check the original article for the detailed evidence. It would be jumping the gun to interpret this as meaning the company is in a comfortable position. Looking strong and being cheap are two completely different things, and this material doesn’t include valuation figures such as PER or EV, so I can’t calculate them.

🛑 Bear case and open questions

Zacks analyzed SanDisk and Micron as appearing oversold, and the original headline asks whether it’s time to buy the dip ^[5]. Oversold doesn’t mean cheap. On the product front, SanDisk announced 'Made For Meta' storage products for Meta Quest and VR glasses ^[6]. Whether new products will translate directly into earnings remains to be seen.

From a short- to medium-term swing perspective, rebound signals are still at the confirmation stage. Peanut sees this stretch first as a potential valuation trap rather than evidence of a rebound. One question remains: Which of the credit rating, new products, and CXMT debate will show up in the numbers first? 🥜
