PickStock checkpoints
(Items to verify, for observation)
- Composition of KOSDAQ declines by sector and stock: check whether drops are concentrated in certain sectors (e.g., cyclical consumer names or small-cap techs on KOSDAQ).
- Foreign and institutional net flows: see if institutional and foreign trades are centered on KOSDAQ, and monitor cumulative flows by time slot.
- Impact of major news variables: confirm persistence of global drivers such as Nvidia earnings notice and Bitcoin ETF inflows on Korean sectors (e.g., AI·semiconductors, crypto-linked names).
- Pre-close volatility (intraday volatility by time) and concentration of daily turnover: distinguish whether KOSDAQ declines are event-driven intraday moves or structural outflows.
- Sector dispersion: analyze why Korean IT·Semiconductors show strength while indices fall concurrently.
