Interpretation guide

What foreign and institutional co-buying means

The Foreign + Institution Co-Buy radar highlights Korean stocks where both foreign investors and domestic institutions are net buyers. When two large professional investor groups buy in the same direction, the flow backdrop can support trend continuation.

Selection rules

The screen looks for names where both foreign and institutional net flow are positive in the latest investor-flow data. It estimates combined net-buying value by multiplying net shares by the closing price.

Combined net buy is an estimated value of foreign plus institutional buying.
Foreign ownership change can help judge whether the flow is becoming persistent.
Net buying relative to trading value shows how influential the flow may be.

How to interpret it

Co-buying is positive, but one day is not enough. If co-buying repeats while the price trends higher, confidence improves. If the price is weak despite buying, the stock may still be absorbing supply.

Two or three consecutive co-buying sessions improve flow quality.
Large net buying with weak price action can mean large sellers are still present.
During KRW weakness, foreign-flow persistence should be checked separately.

How to respond

Co-buying is useful for watchlist construction, but entries still need price and turnover confirmation. In weak markets, define support and invalidation levels before following the flow.
