<li>Structurally, Square’s NAV trade still works. The Hynix stake alone implies a 60%+ discount, well above local norms, with policy tailwinds supporting long-term compression.</li>
<li>Near term, Square’s NAV is a derivative of retail Hynix flows. Today was the first real unwind since the 10th, with retail net selling roughly 5x yesterday’s retail net-sell.</li>
<li>Retail sold both, but Hynix again dominated the tape. Retail is range-trading ₩500ks, and that behavior is the key driver of Square’s short-term NAV inflection.</li>

<li>SK Hynix and SK Square hit L2 flags; cash-only until Dec 24. Margin off, &gt;40% two-day rip triggers halt. L2 lifts if below T-5/+45%, T-15/+75%, and 15-day high.</li>
<li>L2’s usually a non-event, but this time the margin freeze probably smacks Hynix harder. Key trigger is staying below the 15-day high: Hynix ₩587,000, Square ₩324,000.</li>

<li>ADR odds are tiny. Both Samsung and Hynix have thin control stakes, making governance risk too high. Neither is willing to chase a valuation pop at the expense of stability.</li>
<li>Still can’t ignore it, since the ADR chatter is meaningfully swinging the pair trades. Samsung pref spread and Hynix/Square are both getting pushed around.</li>
<li>ADR noise cooled today, but it can easily resurface and skew the setup. Treat as noise, but be ready to hit aggressive reversion trades when it pops again.</li>
