Signal

Samsung's $1T club entry, AMD Data Center +57%, ARM's AI CPU and Lumentum +90% all point in the same direction.

Risk

Above KOSPI 7,500, the multiple can break first if HBM pricing, server DRAM contracts, USD/KRW or foreign net buying turns lower.

Action

Next week, check HPSP, Isu Petasys, INTEKPLUS, Jeju Semiconductor and Apple's memory-cost guide in that order.

KOSPI 7,000 Breakout and Samsung's $1T Club

The single variable on May 6 was foreign buying plus memory pricing power. KOSPI closed at 7,384.56, up +6.45%. The level matters more than the move. The market opened 7,000 for the first time, then did not immediately give it back.

Samsung Electronics rose to KRW 270,000. The daily gain was +16%. Market value entered the $1T club. Locally, that is symbolic. Globally, it means something else. Korea's memory big two are no longer being priced only as local-cycle stocks.

Memory pricing power transfer

By May 8, KOSPI still held a new high at 7,498.00. Samsung Electronics added +2.07%; SK Hynix added +3.31%. The index paused, but the core names did not.

The essence of the 7,000 breakout is not the index level; it is the global repricing of Korea memory.
