Korea’s market just had its best day in months, and chips did the heavy lifting.
The KOSPI jumped 3.29% to 5735.66, triggering a buy-side sidecar for the first time since August, as Samsung Electronics and SK Hynix both surged more than 5%. The move tracked blowout AI-server guidance from Super Micro and SpaceX’s first profitable quarter, plus record chip export data at home. SK Hynix also wrapped its 40-trillion-won buyback a month early, raising questions about what supports chip stocks from here.

00:003 numbers before the open. KOSPI closed at 5,735.66, up 3.29%. Samsung Electronics and SK
00:09Hynix both jumped more than 5%. And the market hit an 8-month high for buy orders,
00:14the first sidecar trigger since August 20. It's Thursday, October 22.
00:19Here's what today's story could mean for the Korean market.
00:22Korea's KOSPI finished above the 5,700 level on Wednesday,
00:26driven by a sharp rebound in semiconductor stocks. Foreign and institutional investors bought
00:32together, lifting the index by 182.92 points. The rally was fueled by renewed optimism in AI
00:39infrastructure demand and a strong export report from Korea. Here's what the numbers show.
00:44Samsung Electronics closed at 223,501, up 5.67%.
00:50SK Hynix rose 5.81% to 1,294,001. Both stocks gave back part of their intraday gains,
00:59which had reached 7 and 8% respectively. On the KOSDAQ, the index added 1.38% to close
01:05at 792.76. Korea's exports for the first 20 days of October climbed 105.4% year-on-year to
01:14$61.6
01:15billion. Semiconductor shipments up 222.5%. Supermicro's first-quarter revenue guidance of
01:22$18.5 to $19.5 billion came in well above the $15.2 billion consensus.
01:29SpaceX posted third-quarter sales of $14.58 billion, more than double a year earlier.
01:35Meanwhile, SK Hynix completed a 40 trillion one-share buyback about a month ahead of schedule,
01:42removing a key source of support for the market.
01:44So what does this mean for stock investors watching the market this week?
01:47The semiconductor rally has strong momentum, but the big question is who will absorb the
01:52selling pressure now that both Samsung and SK Hynix have finished their buybacks?
01:57Earlier, we said that the foreign selling had weighed on the market.
02:00Here's what that actually means for you.
02:02Foreign investors switched to net buying, which is a positive signal,
02:06but the loss of corporate buyback support means the next move will depend on fresh demand.
02:10Watch SK Hynix's third-quarter earnings on October 28th for any new shareholder return plan.
02:16Also watch the Supermicro earnings release on November 3rd,
02:20since it will confirm whether AI server demand is holding up.
02:23That's today's AI Prism, stock investors.
