The stock ignored its own good news last week, so what finally sent it flying? A deal for its biggest competitor.

If you were watching Micron Technology (MU) last week, you might be feeling a little dizzy.

On Friday, the company got the nod it was waiting for: confirmation it has qualified to supply the latest high-bandwidth memory to Nvidia. The stock promptly fell. This followed a drop on Thursday, when an analyst warned that memory-chip prices might be approaching a ceiling. So, good news was bad news, and bad news was also bad news.

Then came the reversal. From that Friday close through Monday, Micron surged +9.9%, leaving the S&P 500’s +0.2% return in the dust.

A Competitor’s Coattails

What changed the market’s mind? The catalyst wasn’t a new Micron filing or a fresh upgrade. According to reports, the stock started rising after its rival, SK Hynix, announced its own new deal with Nvidia. The logic here is a little twisted, but it tells you everything about the current AI frenzy. The thinking goes that Nvidia’s demand for memory is so vast that a win for one major supplier signals a market big enough for everyone. A rising tide lifts all qualified boats.

And Micron’s tide is certainly rising. The company’s revenue is up 85.5% over the last year, a sharp acceleration from its 45.3% three-year average. Its net margin has hit 41.5%, a three-year peak. This isn’t some speculative story stock; it’s a business with a market capitalization of about $1068.9 billion that is firing on all cylinders. The stock’s recent jump even outpaced memory peer WDC, which gained +3.0% over the same period.

Which leaves just one question for investors trying to keep their footing: with fundamentals this strong, why is the stock still trading on a rival’s headlines instead of its own?
