Nasdaq 100 falls about 10% from October high, set to enter correction territory.

A 10% peak-to-trough drawdown is the conventional marker for a correction, but the threshold itself carries no mechanical significance; historically, corrections have been common occurrences within intact uptrends, with only a minority of them extending into bear market territory, and the separating factor has usually been whether the decline reflects multiple compression and positioning washouts or a genuine deterioration in the earnings and credit backdrop. For a concentrated, megacap-weighted index, the composition of the fall matters as much as its depth: drawdowns driven by a handful of the largest names have often resolved faster than those where breadth deteriorates broadly, and the tell is whether equal-weight measures and non-index sectors are confirming or diverging. The established sequence in past episodes is rising implied vol and skew first, forced deleveraging from systematic and leveraged strategies second, and credit spreads widening last; if high-yield and investment-grade spreads remain contained, the equity move has historically been read as a valuation reset rather than a growth signal. What is worth watching next is whether systematic selling pressure exhausts as volatility-targeting exposure resets, how the index behaves around the prior consolidation zone and widely tracked technical levels, and whether dip-buying flow returns at the close of sessions. The calendar follow-ons are the upcoming earnings from the largest constituents and the next round of rate and macro data, since corrections of this kind have tended to find a floor when earnings delivery holds up even as multiples compress. As a market-move headline rather than an event, the signal is descriptive.
