Sandisk (NASDAQ:SNDK) has a major event coming soon: a stock split. In the past, stock splits have caused share prices to rise in anticipation of the split, making them popular events to invest in.
However, I think there are far better reasons to invest in Sandisk's stock split, as its business is looking strong. Its stock is also priced quite cheaply, which really makes it a great buy now.

So, regardless of how the stock reacts after its stock split on Nov. 19, I think Sandisk is a top investment option in the market.
Sandisk manufactures NAND memory, and also devices that those go into. NAND memory is utilized for long-term data storage and can be used in devices like smartphones and solid-state drives (SSDs). AI hyperscalers and their quest to build out as much computing power as possible have eaten up nearly all production capacity for NAND memory, as they need storage devices like SSDs to store massive amounts of data to be used for AI recall.
That shortage has been a huge boost for Sandisk. There isn't a lot that separates Sandisk's products from the competition, so its clients often went with the cheapest option. However, as supply for these units dried up, prices began to rise. For Sandisk, this isn't a problem, because it can now make a far larger profit on each unit sold because its input costs hadn't changed.
This is reflected in Sandisk's financials, as its gross and profit margins have both soared.
This is a major improvement over previous highs and has translated into major shareholder returns. This year, Sandisk is the second-best-performing S&P 500 (SNPINDEX:^GSPC) stock, rising nearly 300% so far in 2026. However, I think it could have more returns ahead of it, as nothing has shifted in the market right now.
The biggest reason why Sandisk and its peers weren't prepared for the AI demand wave is that their clients don't have close working relationships. As mentioned above, its clients utilize the cheapest options available, so that meant bouncing around from supplier to supplier.
Because Sandisk and its peers were operating as cheaply as possible to cut costs, they had no plans to increase production capacity when it wasn't being fully utilized anyway. However, Sandisk's clients have now seen the value in keeping close business ties with them, and Sandisk has started to enter into what it calls "New Business Model" agreements.
This arrangement locks in committed volumes and structured pricing levels, which gives Sandisk a more stable business. This allows the company to better plan for what its cash flows will be, which will allow it to aggressively repurchase shares, which will boost investor returns.
This is great news for investors, and will reduce the cyclical downturn that Sandisk and other memory companies have historically experienced as demand waves end.
However, the stock is priced as if the demand wave will end tomorrow. With the shares trading at less than 4 times forward earnings, the market isn't pricing in any success. I think that's a huge mistake, as Sandisk will now be able to repurchase shares for next to nothing.
A large share repurchase plan will accelerate Sandisk's earnings-per-share growth and will send shares to a far higher level. I think this will be the ultimate catalyst for Sandisk that sends its shares higher throughout 2027, not the stock split.
Sandisk may have had a good 2026, but I think 2027 could be just as strong thanks to sustained demand and a new financial model. Now would be a great time to buy, as the stock is pretty weak thanks to overall AI investment weakness.
