Interpretation guide
How to use institutional net buying in KOSPI
Institutional net buying tracks domestic institutional flows in KOSPI, including pension, fund, insurance, and financial-investment accounts. If foreign flows describe global demand, institutional flows help read domestic rotation and index support.
What it means
Institutional buying shows where domestic capital is adding exposure. Buying during a pullback can be defensive support; buying during an uptrend can confirm broader sector leadership.
- Consecutive buying sessions matter more than one program-driven session.
- Days when both foreigners and institutions buy carry stronger flow confirmation.
- If institutions buy while foreigners sell hard, index upside may remain limited.
Interpretation rules
Institutional flows can be affected by month-end, quarter-end, rebalancing, and dividend season. Read them with cumulative direction and sector distribution.
- Five or more sessions of cumulative buying can indicate short-term rotation.
- If institutional buying overlaps with leading sectors, trend durability improves.
- Without stronger turnover, institutional buying may only mean index support.
How to respond
Institutional flow is useful for building sector watchlists rather than chasing isolated themes. Combine it with foreign flows, breadth, and earnings momentum.
- Sectors bought by both institutions and foreigners deserve priority monitoring.
- For institution-only buying, separate rebalancing flow from earnings-backed demand.
- If institutional buying fades and the index loses its 20-day average, turn more defensive.
