<li>June’s rebalance brings rare moves in key sector indices: HD Hyundai Marine Solution (443060 KS) joins Heavy Industry, while Cosmo AM&amp;T (005070 KS) exits IT.</li>
<li>TIGER flows on June 12 may hit KRW 6B (HD Marine) and KRW 4B (Cosmo), implying 0.3–0.6x DTV impact — notable given both names' low liquidity.</li>
<li>KOSPI 200 flows may fade early, but TIGER sector flows remain stealthy, raising odds of flow-driven price action on June 12 — a potential long-short day trade setup.</li>
