In this article, we will look at the 10 Best High-Bandwidth Memory (HBM4) Value Chain Stocks to Buy According to Hedge Funds.
High-Bandwidth Memory (HBM) has emerged as the primary supply constraint in AI. In the early phase of the AI infrastructure development, GPUs were the primary constraint. While power remains the biggest long-term constraint, memory continues to be a bottleneck in AI development in the short-term.
Goldman Sachs now expects the DRAM supply-demand shortfall in 2026 to reach 4.9%, revising its forecast upward from 3.3%. The firm described it as the most severe shortage in roughly 15 years.
Recently, Nvidia CEO Jensen Huang met with the SK hynix leadership team in Seoul and spoke to CNBC. In his statement to the media company, he warned that global memory shortages could last several years as the industry transitions to the next-generation HBM4 architecture.
The two tech giants, Nvidia and SK hynix, are officially partnering for the long term to co-develop the next-generation AI memory chips.
Chey Tae-won, Chairman of SK Group, remarked:
SK hynix and NVIDIA have been building toward this for years, and this partnership reflects the depth of that collaboration. Together, we are codeveloping the next generation of memory for AI factories and applying AI to how we design and manufacture semiconductors, work that will shape the future of AI infrastructure.
Memory stocks aren’t the only ones skyrocketing as a result of these developments. All the companies involved in the HBM value chain are benefiting, prompting us to write about the 10 best high-bandwidth memory value chain stocks to buy according to hedge funds.
Our Methodology
To compile the list of 10 Best High-Bandwidth Memory (HBM4) Value Chain Stocks to Buy According to Hedge Funds, we considered only companies with a market cap of at least $2 billion. We then looked at companies that either directly designed or manufactured high-bandwidth memory or provided essential infrastructure that enabled its design and manufacturing. The list, therefore, includes companies that offer memory interconnect solutions, HBM controllers, advanced packaging technologies, and semiconductor inspection and testing equipment, among others.
From this list, we selected the top 10 companies that had the highest number of hedge fund investors having a stake in them, based on Insider Monkey’s database of prominent hedge funds as of Q1 2026. Finally, we ranked them in ascending order based on the number of hedge funds holding positions.
