SETUP

The NASDAQ 100 (^NDX) is a market index covered by the Sigmanomics analytics platform. The ^NDX index closed at 30,448.19 on September 23, 2026, reflecting a decline of 1.00% from the previous close of 30,756.61.

WHAT'S DRIVING IT

Over the past 30 days, the index has experienced a modest uptrend with a rally of 2.40%, ranging between 28,753.29 and 30,769.34. The price currently trades above its 20-day moving average of 29,506.71. The 14-day RSI stands at 62.6, in the upper part of its range.

THE RISK

Over the same 30-day window, daily-return volatility was 1.01%, reflecting typical price variability for this index. Across the past 52 weeks, the index has traded between 22,841.81 and 30,769.34, with the current price near the high end of that range.

WHAT WE'RE WATCHING NEXT

Daily-return volatility of 1.01% runs elevated for this index, so price ranges are likely to stay wide — watch how price behaves around its recent range rather than treating any single level as fixed. ^NDX is currently trading 3.19% above its 20-day moving average and sitting in the upper portion of its 52-week range. Its 14-day RSI reads 62.6, currently in neutral territory.
