In the September 21 session, the Nasdaq 100 pushed its relative strength index (a momentum gauge) to 81 as the index reached 30,788. Readings above 70 are typically considered overbought, meaning the rally may be due for a pause or pullback even without a change in the underlying story.
Elsewhere, the picture was more mixed. The Dow Jones Industrial Average was described as stuck in a no-trade zone at 52,500, showing little conviction in either direction. Tesla shares ran into resistance in the $377 to $381 range, while Alphabet's Class C shares tested resistance at $354 on an intraday chart.
Taken together, the session showed technology-heavy indexes stretching further while blue-chip and single-stock moves stalled at defined price levels, leaving traders watching whether the Nasdaq's overbought signal resolves into a pullback or gets ignored as it has in prior weeks.
