📈 갑작스러운 나스닥 선물 변동성 급등, 이유가 뭘까요?

13:50 UTC is 8:50 AM Eastern, which is 10 minutes before the US cash open. That window regularly sees vol spikes because order imbalances from overnight positioning get resolved as liquidity thins right before the open print. Market makers widen spreads, large orders hit a thinner book, and futures react more sharply than they would mid-session.

It can also coincide with pre-market data releases or institutional order flow that front-runs the open. Without knowing the specific date it's harder to isolate a cause, but the time alone explains most of it structurally. That pre-open window is one of the least liquid moments in the US session and NQ is particularly sensitive to it given its concentration in a handful of names.
