Interpretation guide

How to read the daily top gainers

The Daily Top Gainers radar lists the biggest one-day advancers in KOSPI and KOSDAQ, filtered by a trading-value floor. Its purpose is not to chase individual spikes, but to give the fastest daily read on which themes and sectors short-term capital is rotating into.

Selection rules

The screen starts from Naver Finance's per-market top-gainer lists and keeps only stocks with at least 1 billion KRW in daily trading value. That removes near-limit moves in illiquid names and keeps the list focused on gains real money can actually trade.

Up to 10 names per market (KOSPI and KOSDAQ), 20 in total.
Sorted by one-day percentage change in descending order.
Thin moves below the 1 billion KRW turnover floor are excluded.

How to interpret it

A gainer list is the output of one day of flow, so it is not a buy signal by itself. Instead, look at whether several names from the same theme appear together, whether gains come with turnover, and whether larger-cap names are joining the list.

Three or more names from one theme usually mean an active theme rotation.
Moves near +29% to +30% are at Korea's daily limit and tend to stay volatile the next session.
Large caps appearing among top gainers point to market-level flow, not just stock-specific news.

How to respond

Chasing daily spikes is one of the easiest ways to lose money. Treat this screen as a watchlist, not an entry list, and cross-check candidates against the turnover-spike, 52-week-high, and co-buy radars before acting.

Prefer entries on later pullbacks where turnover holds, not on the spike day itself.
Names that also appear in the trading-value-spike radar have attention confirmed by real capital.
Isolated spikes on weak-breadth days are more likely one-off events than rotation.
