<li>FnGuide MKF500 rebal: Fadu finally added, SK Square and ISU Petasys surprisingly reclassified into semis, driving notable passive flow impact into the KRW 15tn semis ETF complex.</li>
<li>TIGER Semis Top 10 is pure free float MCAP screen, all three already Top 10, so inclusion basically locked if rankings hold.</li>
<li>Other five depend on keyword scoring so lower visibility, but still high inclusion odds; expect stacked FnGuide passive flows from June 12 through July and October driving heavy positioning.</li>
