§Winston Score History

The full picture

SK hynix is a South Korean company that makes memory chips used inside computers, smartphones, and data center servers. Its two main products are DRAM (the fast memory that helps devices run multiple tasks at once) and NAND flash (the storage chips that hold data even when the power is off). It is one of the three largest memory chip makers in the world, alongside Samsung and Micron.

SK hynix earns money by selling these chips to large technology companies like Apple, Nvidia, and major cloud providers. It operates mainly from South Korea, with some manufacturing in China, and generates tens of billions of dollars in annual revenue. The company has a strong position in high-bandwidth memory (HBM), a specialized chip used in AI processors, which is currently its biggest growth driver. However, memory chip markets are cyclical, meaning prices can fall sharply during downturns, which creates significant earnings risk.
