Definitions:

Contribution – The weighted impact of a stock’s return on the overall index move
(weight × return). This reflects how much each stock actually moved the index.

Share – The proportion of total index movement attributable to a given stock.
Higher values indicate outsized influence relative to peers.

Impact Efficiency – The ratio of contribution to return, highlighting how effectively
a stock’s price move translates into index impact (primarily driven by index weight).
