Just noticed something pretty interesting about SanDisk -- this AI chip play has absolutely crushed it over the past year. We're talking 1,500% returns since the spinoff from Western Digital back in February 2025. And here's the thing: Wall Street analysts still think there's more upside.

The stock is currently trading around $576, but the median analyst target sits at $690. That's roughly 20% more from here. Some are even more bullish, with targets as high as $1,000 per share. What caught my attention is that many analysts just raised their price targets after SanDisk reported seriously impressive earnings on January 29. Before that report, the median target was only $400. So yeah, Wall Street's clearly playing catch-up with this one.

What's actually driving this? SanDisk is gaining real market share in NAND flash memory -- they picked up 2 percentage points in the 12 months ending September 2025 while Samsung and SK Hynix actually lost ground. The company's also got structural advantages: they run a joint venture with Kioxia, they control their own manufacturing, and they're vertically integrated in ways most competitors can't match.

But the real catalyst has been the AI infrastructure buildout. Memory chip prices literally shot up 50% in Q4 2025 and are expected to jump another 40-50% by Q1 2026. SanDisk's been riding that wave hard -- Q2 revenue hit $3 billion (up 61%), and non-GAAP earnings per share jumped 404% to $6.20. Their guidance for Q3 is even crazier: $4.6 billion in revenue and $13 per share in earnings. That would more than double from Q2.

Here's where it gets interesting though. Wall Street's projecting 156% annual earnings growth through June 2027, which makes the current 80x P/E multiple seem reasonable on paper. But and this is a big but the semiconductor industry is cyclical. Eventually this memory chip shortage will flip to a glut, and when that happens, valuations could get crushed. Nobody knows if that's happening in a few months or over a year, but it will happen.

So is it still a buy? If you can handle the volatility and don't mind the risk of a sharp pullback when the cycle turns, a small position makes sense. Just go in with your eyes open about the cyclical nature of this business. The upside is real, but so is the downside risk when sentiment shifts.
