📈 SanDisk: Questions About the Cycle Amid Price Swings - 2026.10.19

Well, Onion’s here~! Today, let’s talk a bit about SanDisk. When the market is this bumpy, it’s fun to look at the numbers alongside the headlines ☕

Prices Are a Roller Coaster, and the Trend Is Still Up for Debate

Let’s dig into the numbers first. The closing price on October 8 was $1,609.46, but by October 16 it had fallen to $1,299.30. The one-day change on the 16th was -6.85%, with trading volume at 8,882,300. The previous day, the 15th, volume was 13,279,800—the highest during this stretch. Those were days to hold tight to the roller coaster handles 😅

The S&P 500 Story Is the Article’s Claim

According to a Yahoo Finance article, SanDisk is putting up a standout performance in the S&P 500 in 2026 ^[2]. The important thing here is that this is the article’s interpretation. It’s neither a plan announced by the company nor a confirmed outcome. But the article follows up by asking whether the performance could continue next year. That’s exactly the question Onion wants to hear! 💪

Comparing Valuations After the Spin-Off—and the Memory Cycle

According to a Yahoo Finance headline, SanDisk (SNDK) is now worth more than Western Digital (WDC), the company that spun it off ^[1]. Since that’s based on the headline, we can’t verify the specific figures, so let’s just note the direction. It’s fascinating to watch how the independent company has been doing since the spin-off.

There’s also an article looking at the history of cyclicality for Micron and SanDisk and asking whether this time will be different ^[3]. Memory has always been a cyclical business, so this is the first question that comes to mind even for Onion, who’s been at it for 30 years. There’s a joke that the memory industry has a great memory—it remembers every past cycle. Well, there’s a dad joke for you 😂

There’s also a cloud angle. A headline says SanDisk’s next-generation chips could significantly cut costs for cloud giants ^[4]. From the headline alone, though, it sounds like this isn’t relevant to ordinary users. We haven’t been able to check the article’s full text, so I can’t get into product specs or detailed figures; I’ll just note the direction.

Onion thinks the first thing to watch for the bullish scenario to hold up is whether the industry cycle actually changes, not just whether prices rebound. We should also watch whether the cloud chip story turns into real orders—that’ll make the picture clearer.

Two Variables Remain

First, is the trend really different from past cycles? Second, will the cloud chip story translate into SanDisk’s earnings? Add in the question of where prices will find direction, and there’s plenty to think about. So here’s today’s one-line question: Will this cycle really be different? 🧅
