Wall Street focuses on Samsung Electronics and SK Hynix... AI bottleneck stocks also stand out

A growing number of U.S. investors are taking another look at Samsung Electronics and SK hynix. Kim Dohyun, the CEO of a techstock investment YouTuber featured in the article, explained that as AI demand rises and memory supply tightens, the bargaining power of memory semiconductor companies is increasing. He said that, unlike in the past, memory makers can now create a stable earnings structure through longterm supply contracts and fixed unit prices, and that valuations such as the pricetoearnings ratio (PER) could therefore be reevaluated. He added that the DRAM market has a strong oligopolistic structure centered on Samsung Electronics, SK hynix, and Micron, making barriers to entry high. He also mentioned NVIDIA's corporate bond issuance, SpaceX's acquisition of an AI company, and the restructuring of data centers in line with the transition to nextgeneration AI accelerators. Kim analyzed that bottlenecks are emerging across data centers—not just in chip replacement, but also in power, networking, CPUs, and optical communications—driving up demand for related components and equipment.
