<li>If the three non-IT names exit IT, passive flows hit hard: SK Square/LG Electronics ~0.4× DTV out, LG Corp ~0.8× DTV out, new IT entrants ~0.2–0.25× DTV in.</li>
<li>If KRX surprises next Tuesday, kicking three names from IT, expect immediate tape reaction—market memory exists, but the scenario isn’t priced, unlike 2023 Kakaopay, so instant price impact is likely.</li>
<li>If this happens, June 11 turns into a chunky basket-flow day: SK Square (~15% weight) out, next-tier caps see ~0.15–0.2× DTV inflow, except ultra-liquid names like Hanmi Semi.</li>
