description

Korean market quotes (KOSPI / KOSDAQ / SK Hynix / Samsung) with capitulation-reversal detection. Use whenever reading the US memory/storage complex (MU / DRAM / SNDK / WDC / STX / SMH) — Korea is the SOURCE market and leads the US tape; Longbridge does not cover KRX. Triggers: 韩国 / 韩股 / KOSPI / 海力士 / SK Hynix / 三星 / Samsung / 韩国爆仓 / 韩国追保 / 存储板块见底了吗 / 洗盘结束了吗 / capitulation / Korean margin calls / has the flush ended.

Korea Market

Korean quotes + a capitulation-reversal test, from the Yahoo Finance chart API. Stdlib only, no third-party deps, goes through _shared/client.py (cache + throttle + output contract).

Why this skill exists

Longbridge does not cover KRX. It returns [] for 000660.KS / 005930.KS.

The tempting workaround — read Korea through the US-listed proxies EWY (Korea ETF) and KORU (3× Korea) — lies to you:

• They are FX-contaminated (a won move shows up as a price move).
• They are frozen while Seoul is still trading — they only reprice during US hours.

The 2026-07-14 proof. Reading the proxies, EWY looked ~flat (−0.13%) — nothing to see. The real Seoul tape that same session:

	Seoul (real)	Proxy said
SK Hynix	low −9.1% intraday → closed +2.9% on 1.55× volume (heaviest of the entire selloff)	EWY "flat"

That was a textbook capitulation bottom, and the proxy hid it completely. Anyone watching EWY would have missed the exact session they were waiting for.

Rule: when the question is about Korea, read Korea.
