Interpretation guide

How to use one-year return leaders

The One-Year Return Breakouts radar shows where capital has stayed for a full market cycle. It helps identify durable leadership, dominant themes, and stocks that have already proven relative strength beyond a short-term news move.

What it means

One-year leaders often reflect sustained earnings expectations, structural themes, or persistent liquidity support. Comparing KOSPI and KOSDAQ leadership also helps separate large-cap leadership from growth-stock leadership.

One-year return is a long-term relative-strength measure.
Market-cap weight shows how much influence the stock has on its broader market.
High turnover alongside high return suggests the name still has active sponsorship.

Interpretation rules

If the leaders cluster in one industry, the market has a clear dominant theme. If leadership is scattered, the market may be more stock-specific and less directional.

A one-year return above 100% is strong long-term momentum.
High return with low liquidity increases execution and reversal risk.
Rapid turnover in the leader list means leadership quality is weak.

How to respond

One-year winners can be close to crowded territory, so they should not be bought mechanically. Confirm earnings, valuation, liquidity, and broader market health before acting.

Use staged entries and explicit invalidation levels for extended stocks.
Track industries that repeatedly appear in the leader list as medium-term themes.
A break below both the 20-day and 50-day averages can signal fading momentum.
