Samsung Electronics' stock price skyrocketed as it became the first in the world to ship samples of its 7th-generation high bandwidth memory (HBM4E), a next-generation memory semiconductor. Consequently, Samsung Electronics set a record by surpassing a combined market capitalization of 2 quadrillion won for its common and preferred shares.

According to the Korea Exchange on the 29th, Samsung Electronics' common shares closed at 317,000 won, up 5.84% from the previous trading day. Its market capitalization was tallied at 1,853.2703 trillion won. The preferred shares (Samsung Electronics Preferred) also finished trading at 202,500 won, up 6.08%, recording a market capitalization of 162.4802 trillion won. The total combined market capitalization of common and preferred shares reached 2,015.7505 trillion won, surpassing the 2 quadrillion won mark. This is the first time a single company's market cap, including preferred shares, has exceeded 2 quadrillion won. Following the breach of the combined 1 quadrillion won market cap in January of this year, the company's value doubled in approximately four months.

The backdrop for the stock's surge on this day was the news that the company provided customers with the world's first samples of the 7th-generation HBM (HBM4E) product, a core component of artificial intelligence (AI). After initially supplying the mass-produced 6th-generation HBM4 to the industry in February, Samsung Electronics showcased the next-generation product sample about three months later, accelerating its efforts to dominate the AI memory market.

Market forecasts also appear positive. Kim Dong-won, Head of the Research Division at KB Securities, stated in a report that "the memory market will experience an intensifying supply shortage and an expanded price elasticity in 2027," raising Samsung Electronics' target price from 45,000 won to 53,000 won.
