These past couple of days, I took out $Kingsoft Cloud(KC.US) to look at again. It finally feels like it's not just a stock propped up by hype anymore. The Q4 results just released on March 25th show revenue of about 27.6 billion RMB, up 23.7% year-over-year. Public cloud revenue was 19 billion, up 34.9% YoY, and AI-related billing surged by 95%. Most crucially, AI business now accounts for nearly half of public cloud revenue, which shows it's not just riding the AI wave—it's genuinely starting to benefit from it.

So it's no surprise to me that KC has been getting renewed attention from the market recently. Before, people saw it as an old China concept cloud story—not very exciting or solid. Now it's different. The market is willing to view it as an "AI cloud elastic play," where sentiment and performance are starting to align.

But I still say this: you can watch this stock, but don't get carried away chasing it. The very thing that makes it easiest to rise now is also what makes it most vulnerable to a sell-off. Everyone knows AI growth is fast, but once the market shifts its focus from "growth rate" to "profit margins" and "sustainability," the volatility will be significant. Plus, as a China concept growth stock, it can surge fast when sentiment is positive, but when sentiment turns, it won't hold back on the way down either.
