$SKHYNIX (SK하이닉스) – When One Share Triggered a Market Shock Today, I witnessed one of the most unusual market events I've seen in a long time. At exactly 8:00 PM (KST), SK Hynix on Toss Securities executed just ONE share at approximately KRW 1,272,000. Immediately after that single trade, Volatility Interruption (VI) was triggered, temporarily restricting normal trading in the Korean market. However... Hyperliquid never stopped trading. While the Korean market was effectively paused, trading on Hyperliquid continued as usual. Within moments, SKHYNIX Last Price on Hyperliquid briefly collapsed to around $927. The Biggest Question Unfortunately, everything happened so quickly that I couldn't verify the Mark Price at that exact moment. Because of that, I can't say with certainty whether existing long positions avoided liquidation or whether Mark Price also fell enough to trigger liquidations. That conclusion requires the actual historical Mark Price data. I don't want to speculate. What We Do Know One fact is undeniable. While the Korean market was temporarily halted after a single executed share, Hyperliquid remained fully tradable. During that short window, an extraordinary price gap appeared. Once VI was lifted, SK Hynix resumed trading around KRW 1,754,000, and Hyperliquid quickly recovered to approximately $1,138. For a brief moment, there was a massive price dislocation between markets. My Biggest Mistake Just before this happened, I had successfully closed my LBank SKHYNIX short position for a profit. Normally, this type of price gap is exactly what I look for. Gap trading has always been one of my favorite strategies. But this time... I froze. I simply stared at the chart. Looking back, the reason wasn't technical. It was psychological. Fear. When the market moves that violently, your brain can stop processing opportunities and focus only on uncertainty. Even when you've traded price gaps many times before, executing in a real flash event is a completely different challenge. What I Learned Today's experience reminded me that successful gap trading isn't just about understanding charts or market structure. It's also about having the discipline and confidence to execute your strategy when volatility is at its highest. During those few minutes... Someone may have lost everything. Someone else may have captured one of the best trades of the day. As for me, I missed the opportunity. But next time, if I ever see another "one-share VI event" creating this kind of market dislocation, I'll be far better prepared.
