Hi Matt, I found an indicator on Trading View that seems
pretty good for automatically drawing supply and demand zones.
It is called the "Sattam Supply \ Demand". Please let
us know what you think. Thanks Paul

Same here Matt. I was in a small jet waiting to leave
Logan (Boston) airport when we heard of the first tower.
Needless to say, that flight was grounded. I hopped a
bus heading back home. Cell service wasn't working until the
bus was out of Boston.

The global
High
Bandwidth Memory (HBM)market is an oligopoly controlled
almost entirely by three chipmakers, often referred to as the "Big
Three". These companies collectively command
over 95% of
global HBM capacityto fuel AI accelerators like
NVIDIA's Blackwell and
AMD's Instinct series. [

The "Big Three" HBM Manufacturers
SK Hynix(Market Leader
~56%–58% share): The South Korean manufacturer pioneered
the first HBM chip in 2013 and retains a dominant market position.
Its stronghold is heavily anchored by an early, exclusive
partnership supplying HBM3 and HBM3E to
NVIDIA. SK Hynix has
completed development on its 12-layer HBM4 technology to maintain
its lead.[

Samsung Electronics(~21%
share): Despite leading the broader, conventional DRAM
market, Samsung trails in the high-margin HBM segment. It acts as a
primary HBM supplier for
AMD's Instinct GPUs and is
aggressively deploying its massive R&D resources to ramp up
mass production of sixth-generation HBM4 to reclaim market
share.[

Micron Technology(~21%
share): As the only major U.S.-based memory manufacturer,
Micron entered the HBM market later but has aggressively closed the
gap using its highly power-efficient HBM3E. Backed by U.S. federal
incentives, Micron has already
completely sold out its HBM
capacity through 2026 and 2027.[

Key Ecosystem Enablers
While the "Big Three" manufacture the memory layers, they rely
heavily on specialized semiconductor partners to package and
integrate the technology: [

Foundry & Base
Logic:TSMC(Taiwan Semiconductor
Manufacturing Company)creates the critical "base logic
die" that the memory chips sit on. Its CoWoS
(Chip-on-Wafer-on-Substrate) advanced packaging lines are the
primary bottleneck for global HBM availability.[

Design IP &
Tools:Companies like
Synopsys,
Cadence Design Systems, and
Rambusprovide the foundational architectural IP and testing
software required to manage complex 3D-stacked memory.[

Advanced Packaging
(OSATs):Firms like
ASE Technologyand
Amkor Technologyprovide
backend assembly and packaging support to integrate HBM onto GPU
interposers.[

Sorry to hear this Matt. I've found during these times, it is better to seek advice from the nurses. They know what's really going on.
These are hard times for those of us that have to watch! Hope she makes it back home soon.

Somehow I don't think 5 holds for long. It seems like it has been tested too many times. Plus investors are sick of this company moving like a sloth.
