The biggest drag was chips and memory: the group fell 4.25%, which took about 0.73 percentage points off the index. Next came the Mag 7 (-0.97%, 0.55 points) and software and other tech (-2.95%, 0.19 points). The selling was narrow: 53 of 100 stocks rose, so the fall sat in the largest names. Food and household (+2.93%) and industrials (+1.27%) finished higher.

On the calendar today: ISM Manufacturing PMI, October 2026 data (10:00am ET). Today’s full schedule. This block says where the move sits, from the same quotes as the map. The news behind it is a separate question. Points are each group's share of the map's move in percentage points, weighted by our latest market-cap snapshot, so the total lands near the headline figure without matching it to the hundredth. The Nasdaq 100 caps its largest weights and our plain cap weighting does not, so the Mag 7 count for more here than in the official index.
What Is Driving the Nasdaq 100 Today?
Across the 100 stocks with data (after-hours change vs today's 4:00pm et close, as of 7:59:29pm ET), the cap-weighted average move is +0.04% and the equal-weight average is +0.40%, with 85 up and 8 down. A cap-weighted number well below the equal-weight one means a few giants are dragging the headline figure; the reverse means the average stock is weaker than the headline.

Drag and lift figures are each stock's contribution to the cap-weighted move, in percentage points; they update with the map. Weights come from our weekly market-cap snapshot, so the contributions add up to close to the market move quoted with the map, not exactly to it. On the main map that move is SPY's; on the Nasdaq 100 map it is the index's.
Nasdaq 100 Heatmap FAQ
- Is this Nasdaq 100 heat map live?
- Yes. Prices refresh every 10 seconds while the market trades and every five minutes when it is closed, as long as the page is open. The time beside the refresh button shows when they were fetched, to the second. Before the open and after the close, the Pre-market and After-hours buttons color the map by extended-hours moves. When the market is closed, the map shows the last completed session.
- Which companies are on the Nasdaq 100 heatmap?
- All 100 Nasdaq 100 companies. Alphabet has two share classes in the index, GOOG and GOOGL, and they share one block sized by Alphabet’s whole market value. We check the membership every week.
- Is there a Nasdaq 100 heat map for tomorrow?
- No. A heat map shows moves that have already happened. The closest thing is the pre-market map: from 4:00am ET, the Pre-market button colors each stock by its move since the previous close. Pre-market prices are thin and often reverse at the 9:30am open, so treat that map as a watchlist rather than a forecast.
