SK hynix sheds 95,000 won at the open as hike odds jump to 86% from 69%

SK hynix gave up 95,000 won a share against a 1.812 million won close, and that 5.24% is 1.67 times the KOSPI's 3.14% ^{[4][24][20][1]}. The two steepest falls among the large caps were a chipmaker and a component maker, Samsung Electro-Mechanics at 5.21%. Hyundai Motor was cut 4.31%, harder than Samsung Electronics at 3.66%. LG Energy Solution lost 1.39% ^[6][5][29]. On the KOSDAQ, Rainbow Robotics fell 3.90% and EO Technics 4.15% ^[7].

A 0.3% monthly core reading compounds to about 3.7% a year, and the 0.4% headline to about 4.9% ^[8][23]. Off a core figure that only slightly exceeded forecasts, futures moved 17 points on a September hike, from 69% to 86%. That takes implied odds from roughly 2.2 to 1 up to about 6.1 to 1 ^[8][9][22].

The Philadelphia Semiconductor Index closed 1.81% higher on the 11th, with the Nasdaq up 0.96% and the S&P 500 up 0.86% ^[11]. Set against SK hynix at the 14th open, that is a spread of about 7 percentage points on the same industry across a weekend ^[25]. The report carries the August CPI readings ^[31], and it says the US rebound came on lower oil prices and that the gains failed to calm Korean markets ^[28].

Ahn So-eun, an analyst at KB Securities, put crude first. "Oil price gains have paused, but upward pressure remains after the meeting on the Strait of Hormuz was postponed," said Ahn ^[17]. "Core CPI came in above expectations, heightening concerns about a September rate hike, while high oil prices and high interest rates are again weighing on consumer spending," she said ^[18].

The University of Michigan's September sentiment index came in at 47.8, which is 4.7 points below the 52.5 forecast and the lowest since May ^[15][26]. One-year inflation expectations rose to 4.6% from 4.0%, and five-year expectations to 3.4% from 3.3% ^[16].

In my view the gap between SK hynix and the index is mostly a rates move. A print that beat forecasts slightly moved 17 points of hike probability, and the most-owned high-beta name in Seoul takes that first ^[8][22]. The counter-thesis is crude. The postponed ministers' meeting keeps oil bid, chips are the liquid way to sell Korea, and 1.39% in LG Energy Solution next to 5.24% in SK hynix is a liquidity ranking ^[13][6][4]. If the KOSPI recovers while WTI resumes the climb it broke off after eight sessions, oil was not what was being sold ^[12]. If the FOMC holds in September and Seoul still does not get back to 6,909.91, the hike was not either ^[19].
