KOSPI: check the weight of large companies
A market-cap-weighted index can be driven by a few large stocks. Compare its change with equal-weighted movement, sector indexes and turnover.
KOREA MARKET
Read Korean indexes and investor flows in the same context
KOSPI and KOSDAQ have different structures and risks. Connect index changes with currency, sector weights, participant trading and company disclosures.
LOCAL MARKET GUIDE
Six checks for the Korean market
Compare values from the same session and venue instead of mixing different aggregation bases.
KOSDAQ: pair growth potential with volatility
Its higher growth and small-cap exposure can be sensitive to rates and liquidity. Separate company events such as trials and contracts from financing disclosures.
Participant flows: separate period, market and instrument
Foreign, institutional and retail net purchases are accounting totals with counterparties. Review persistence, spot versus futures and sector distribution rather than one day alone.
KRW/USD: effects differ by company and investor
A weaker won does not benefit every exporter equally. Check sales currency, imported inputs, hedging, foreign-currency debt and foreign investor flows.
Sector weights explain gaps between indexes and experience
Semiconductors, autos or biotech can drive an index. Companies inside one sector still have different customers and value-chain positions, so common movement can have different causes.
Filings and schedules: read originals and corrections
Earnings, offerings, convertible securities, ownership changes and suspensions require the original filing. Check submission date, covered period, amendments and attachments.
