History Says Memory Stocks Like Micron and Sandisk Rarely Stay This Profitable for Long. Here's the Case for Why It's Different This Time.

The representation marketplace is having 1 of its champion humanities runs ever, helping assistance the stocks of some Micron Technology (NASDAQ: MU) and Sandisk (NASDAQ: SNDK). Both person seen their gross soar and their gross margins balloon, starring to grounds profits and currency flow.

Micron is 1 of the large 3 DRAM makers, on with Korean companies SK Hynix (NASDAQ: SKHY) and Samsung, portion it gets astir a 4th of its gross from NAND (flash) memory. Sandisk, meanwhile, is simply a pure-play flash representation maker. The emergence successful some representation markets is straight linked to the artificial quality (AI) infrastructure build-out, though the dynamics down the existent supply-demand imbalances are a spot different.

Missed Nvidia successful 2009? This Rare Signal Is Flashing Again. In 2009, a "Double Down" awesome flashed for a little-known chipmaker called Nvidia. For the archetypal clip successful years, that aforesaid "Total Conviction" awesome is flashing for a institution 1/100th the size of Nvidia. Continue »

Flash representation was successful a large bull marketplace during the COVID-19 pandemic, arsenic stay-at-home mandates led to a surge successful request for electronics, which are dense users of flash memory. This led representation makers to summation their NAND capacity, portion request crashed aft the pandemic ended. This led to a monolithic oversupply of NAND, antagonistic gross margins, and to the large 3 representation makers reducing capableness and turning their attraction to much lucrative DRAM.

However, with the AI boom, information centers soon needed monolithic endeavor solid-state drives (SSDs) packed with NAND to store grooming data, greatly expanding request soon aft capableness was cut. Meanwhile, the emergence of high-bandwidth representation (HBM), a specialized signifier of DRAM utilized successful the AI build-out, became the absorption for the large 3 DRAM makers, and they were successful nary unreserved to summation NAND capacity. The effect was a supply-constrained flash representation marketplace amid soaring demand.

A akin dynamic was astatine play successful DRAM, arsenic graphics processing units (GPUs) and different AI chips needed to beryllium packaged with HBM to trim latency and amended powerfulness efficiency. As request for GPUs grew, truthful did request for HBM. As DRAM makers focused connected expanding HBM capacity, the full DRAM marketplace became undersupplied, and prices roseate sharply.

Historically, the representation marketplace has been highly cyclical, with ample boom-and-bust cycles. As mentioned previously, the past NAND representation rhythm collapsed, starring representation companies to dump proviso astatine prices beneath what it outgo them to manufacture. This is simply a large crushed wherefore representation stocks commercialized astatine single-digit guardant P/Es contempt seeing accelerated growth.
