Micron's Milestone Week: CEO Triggers $38.5 Million Stock Sale at a 52-Week High

Micron Technology crossed a historic threshold to close May with a market capitalisation of $1.1 trillion, planting itself among the ten most valuable US corporations. The catalyst was a single trading session on Tuesday, 26 May, when the stock rocketed more than 19% on a wave of analyst upgrades and reports of tightening supply in the High-Bandwidth Memory (HBM) market. Over the full week, the shares added roughly 29%, closing on Friday at €833.10 — a new 52-week high and more than ten times their level exactly one year earlier.

Right in the middle of that rally, Chief Executive Sanjay Mehrotra filed a Form 144 on 29 May signalling his intention to sell 40,000 common shares worth approximately $38.5 million. The disposal is routed through the Mehrotra Family Trust and operates under a Rule 10b5-1 plan that the CEO established back on 30 January 2026. It is strictly a planned sale, not a spontaneous one: the same trust had already offloaded 40,000 shares for roughly $21.5 million on 1 May, and this latest filing simply continues a pre-arranged programme. Whether the transaction actually settled yet is not disclosed in the filing.

The stock’s technical picture is flashing caution despite its fundamental strength. The Relative Strength Index sits at 31.4 — but using US methodology, a reading above 70 signals overbought conditions, and the instrument is widely considered stretched. The share price now trades more than 185% above its 200-day moving average. The former resistance zone around $956 (on the US listing) has been broken and, if momentum fades, that level will become the first line of support. On a year-to-date basis the gain exceeds 200%, and the rally has been fuelled by a complete re-rating of the company from a cyclical memory supplier to a structural beneficiary of AI infrastructure.

Should investors sell immediately? Or is it worth buying Micron?

UBS underscored that shift with a spectacular target increase, lifting its price objective from $535 to $1,625. The bank cited sustained pricing power in HBM, where Micron’s entire 2026 capacity is already sold out under long-term supply agreements with strategic customers. That structural move away from the volatile spot market — and toward fixed-price contracts with hyperscalers — is the core reason for the premium the market now assigns to the stock. The high-bandwidth memory segment is effectively a bottleneck for AI training clusters, and Micron is capitalising on the scarcity.

All eyes now turn to 24 June, when the company reports third-quarter results. Management has guided for quarterly revenue of $33.5 billion and a gross margin near 81%, building on the $23.86 billion in sales and $13.79 billion in net profit booked in Q2. Investors will also scrutinise progress on the ramp-up of 1-alpha DRAM production at the Manassas, Virginia, facility and any updates on the next-generation HBM4 roadmap. Before that, a busy macro calendar — ISM manufacturing data, JOLTS job openings, and the US employment report on 5 June — could sway sentiment. A strong labour market reading would likely temper rate-cut expectations, putting growth stocks such as Micron under pressure, but the long-term narrative built on HBM scarcity seems likely to dominate the conversation for now.
