Siebert CIO Mark Malek Backs Micron (MU) Buy Call After $54.23 Billion Quarter
2026-10-08 | COINOTAG
Mark Malek, chief investment officer at brokerage Siebert Financial, called Micron Technology (MU) a buy on Wednesday, while rejecting the idea of owning the memory maker forever. His endorsement landed on a session in which the stock did the heavy lifting for its entire sector: MU gained 4.06% to close at $1,088, leading the advance among chipmakers.
The call came on the heels of a $54.23 billion quarter for the memory company, the figure highlighted in connection with his recommendation.
In laying out his position, Malek drew a distinction between a favorable view of the shares and permanent ownership, pushing back on the notion of holding the company indefinitely.
Micron Technology, headquartered in Boise, Idaho, is one of the world's largest producers of memory semiconductors. Its core products — DRAM and NAND flash memory — power personal computers, smartphones, servers, and data centers, and memory components have taken on growing importance as artificial intelligence infrastructure expands worldwide. The company trades on the Nasdaq under the ticker MU and competes with Samsung Electronics and SK Hynix, the two Korean electronics giants, in the global memory market.
The memory business is historically cyclical, swinging between periods of tight supply and pricing strength and periods of oversupply and downturns — a pattern that sets memory makers apart from corners of the semiconductor industry with steadier demand. That rhythm offers one lens on a stance like Malek's: a favorable view of the shares today, without a commitment to hold them through whatever phase of the cycle comes next. For readers tracking the sector, the swing factors are the industry's own mechanics — the supply Micron, Samsung Electronics, and SK Hynix bring to market, where memory pricing lands, and how demand from the PC, smartphone, server, and data-center buyers of DRAM and NAND evolves.
