Why SK Innovation Rose Near 10% as China Halted Fuel Exports

SK Innovation rose around 10% on Friday as Chinese refiners halted fuel exports from October, lifting expectations of wider refining margins for Korean refiners. S-Oil gained in the 7% range and GS, the holding company with refining affiliates, in the 2% to 6% range. The index itself added only 0.46% to close at 7,003.74. This post is about that single sector move and the mechanism behind it, because the mechanism is less obvious than the headline suggests. The shock came from the product side, not the barrel International crude did spike. WTI rose 2.18% to $92.39 and Brent rose 2.4% to $100.36, pushing back above the $100 line. But the source gives two separate drivers for that move, and they are not interchangeable. One is Middle East geopolitical tension, which is a crude-supply risk story. The other is that Chinese refiners effectively stopped exporting gasoline, diesel and other refined products from the start of October, citing inventory restocking. That second item is a prod...

Foreigners Sold Samsung and SK Hynix, the KOSPI Rallied Anyway

Foreign investors sold Samsung Electronics and SK Hynix heavily on Thursday morning, yet the KOSPI still closed up 1.95% at 6,971.35. That gap between who was selling and what went up is the single most informative detail of the October 1 session, and it is the only thing this post is about. The daily wrap-up covers the full tape; here we take apart one question: if foreigners and retail investors were both net sellers of the KOSPI, who actually paid for the rally, and how durable is a rally financed that way? The flow picture the headline hides The closing flow data on the KOSPI reads like a down day. Foreigners finished as net sellers of 597.2 billion won. Individuals were far bigger net sellers at 1.234 trillion won, which the source data attributes to likely profit-taking. The only net buyer among the three groups was the institutional side, at 305.6 billion won. On a naive reading, 305.6 billion won of institutional buying is a small number to set against roughly 1.8 trillion won ...

KOSPI Foreign Selling Was a Rotation Out of Tech and Banks

Foreign investors sold over 2 trillion won of KOSPI shares Wednesday, yet bought metals and chemicals while dumping electronics and financials. The headline flow number looks like a flight from Korean equities. The sector breakdown says something more specific happened, and the difference matters for how the next few sessions should be read. One flow, two directions The aggregate is stark enough: foreign investors were net sellers of 2.0536 trillion won on the KOSPI, their second consecutive session of large-scale selling. Institutions added 771.8 billion won of net selling, for a combined total of roughly 2.8 trillion won, and individual investors absorbed most of it with 1.1721 trillion won of net buying. But the foreign flow was not a uniform reduction of Korea exposure. It was split cleanly along sector lines: Electronics: 314.5 billion won of net foreign selling Financials: 285.5 billion won of net foreign selling Metals: 100.8 billion won of net foreign buying Chemicals: 133.2 bi...

KOSPI's 2.9 Trillion Won Foreign Sell-Off and Who Absorbed It

Foreign investors sold a net 2.9 trillion won of KOSPI shares on Tuesday, and retail buyers absorbed most of it while the index lost just 0.27%. That flow split — the largest force in the session — is the theme worth taking apart, because the exact figures were 2.903 trillion won of foreign net selling against 1.1432 trillion won of individual net buying, and the gap between the size of the outflow and the modesty of the closing loss says a lot about where this market's support currently comes from. The split, in numbers The KOSPI closed at 6,870.81, down 18.93 points or 0.27%, its second consecutive decline after the previous session's drop of more than 2%. Behind that headline, the investor-type ledger was lopsided: foreigners net sold 2.903 trillion won, individuals net bought 1.1432 trillion won, and institutions added a comparatively small 121.1 billion won. The KOSDAQ ran the same pattern in miniature — and finished in the opposite direction. Individuals net bought 148.6 ...

Foreign Investors Sold Samsung and SK Hynix as US Yields Spiked

Foreign investors sold 3.601 trillion won of KOSPI stocks on Monday, and Samsung Electronics and SK Hynix took the hardest hits as US Treasury yields spiked. That single flow — a concentrated foreign exit from Korean semiconductor large caps, transmitted through the US bond market — is the theme this post takes apart. The daily wrap-up covers the full tape; here we look only at who sold, why the selling landed where it did, and what would tell us whether it continues. The size and shape of the exit The flow numbers on the KOSPI were lopsided. Foreign investors net sold 3.601 trillion won and institutions net sold another 1.333 trillion won, while individuals bought 3.2866 trillion won against them. That retail bid absorbed a meaningful share of the supply, but it could not hold the index, which closed at 6,889.74, down 2.70%, surrendering the 7,000 line it had held for four sessions. The selling was not spread evenly. The electricals and electronics sector, home to the semiconductor gi...

KOSPI's Rally to 7,171 Met a 1.6 Trillion Won Retail Sell Wall

Retail investors sold a net 1.6 trillion won of KOSPI stock on Tuesday, turning an early surge to 7,171.44 into a close of just 7,017.91. That single flow — individuals dumping 1,606.8 billion won of shares while foreign investors finished as modest net buyers of 76.2 billion won — is the story of the session, and it deserves a closer look than a one-line mention in a market wrap. The daily summary already covers what moved; this post is about who was selling, why the selling landed exactly where it did, and what would tell us whether it was a one-day cash-out or the start of something heavier. The flow, in plain terms On the KOSPI, the three main investor groups finished Tuesday like this: Individuals: net sellers of 1,606.8 billion won — described in local reporting as large-scale profit-taking Institutions: net sellers of 121.8 billion won Foreign investors: net buyers of 76.2 billion won The asymmetry is stark. Retail selling outweighed foreign buying by a factor of roughly twenty,...

KOSPI 7,000 Rally Hid More Losers Than Winners

KOSPI closed at 7,007.72 on Monday, up 1.65%, yet 552 stocks fell against only 310 that rose — a rally carried almost entirely by a few semiconductor heavyweights. That single statistic is the most important thing that happened in the Korean market this session, and it deserves a closer look than a headline number allows. The index reclaimed the 7,000 line for the first time in seven sessions, but the median stock on the board had a down day. How an index rises while most stocks fall The mechanics are not mysterious, but they matter. KOSPI is a capitalization-weighted index, which means the largest companies move it far more than everything else combined. On Monday, the buying was funneled into exactly those names. Samsung Electronics gained 4.98% to 274,000 won, and the trading value in that single stock reached roughly 5.85 trillion won — the largest on the board. Its preferred shares did even better, rising 6.07%. SK Square added 4.45% and Samsung C&T 4.70%. When names of that s...
