Sector × Period Return Heatmap
Glossary
Buying acceleration
This window's net buying minus the previous equal-length window's. Positive means the buying force is strengthening — it does not mean the price will rise.
Market-cap weight
The sector's share of TAIEX market value; it sets the dot size on the chart.
Foreign & trust both buying (土洋同買)
Taiwan-market jargon for foreign investors (洋) and investment trusts (土) both net buying the same sector over the period; aligned flows from the two are usually given more weight.

What is sector rotation?
Sector rotation is the movement of market money between industries. This page aggregates the three major institutional investors' net buy/sell across each sector's constituents and maps money flow as net buying × buying acceleration, showing which industries institutions are accumulating and which they are trimming; period returns are computed from official TWSE sector indices. Data updates daily after the close.
