S&P 500 and Nasdaq: opening and first moves

S&P 500 today starts with a market opening without a clear direction and with a very clear reading for anyone coming into the session looking for opportunity: money is flowing into banks and defensive stocks, but it is still leaving part of technology. At 3:30 p.m. Madrid time (8:30 a.m. Mexico City), Wall Street opened with mixed signals after Monday’s mixed close, when the S&P 500 finished at 7,807.24 points, the Dow Jones at 51,850.55 and the Russell 2000 at 2,794.48. Before the bell, futures were already setting the day’s tone: the Dow futures were up 391 points, the S&P 500 futures were down 4.50 points and the Nasdaq 100 was falling 210.25 points. That split anticipated exactly the message at the open: relative strength in financials and pressure on growth and semiconductors. Yahoo Finance highlighted before the open that the Nasdaq 100 was arriving weaker due to doubts about AI valuations, while the Dow was finding support in bank earnings.

The picture in the first few minutes points to an S&P 500 very close to record highs, but with less internal breadth than it may seem at first glance. The broad index is not falling because of generalized market weakness, but because of specific pressure on technology and chips. The Nasdaq 100, where the real sensitivity of this session lies, came into the open under pressure from the earlier semiconductor sell-off and from a renewed market debate: whether expectations around the AI investment cycle still justify such demanding multiples. When the market opens like this, what matters is not just whether the index is up or down a few tenths, but who is carrying the market and who is no longer doing so. Today, in that first test, leadership is not in pure growth.

Dow Jones: opening supported by earnings and rotation

The Dow Jones arrives at the open with a clear tactical advantage over the Nasdaq. The reason is not technical, it is sectoral. Banks have kicked off third-quarter earnings season and the market is rewarding those institutions that beat or hold expectations better than the rest. In its pre-market coverage, Yahoo Finance pointed to gains in Goldman Sachs and a positive reaction across the financial complex, while JPMorgan and Wells Fargo arrived with more mixed reads after their results. That favors the Dow because it is an index with a heavier weighting in mature stocks, financials and healthcare, and less exposed to the extreme volatility of the chip universe.

The key here for investors is not to stop at the headline of “Dow stronger than Nasdaq.” The key is to understand the rotation. If money is leaving high-duration technology and moving into banks, healthcare or defensive consumer names, what changes is not just the color of the day: it changes the kind of risk the market is willing to pay for. In addition, the market has another huge reference on the table this week: U.S. inflation. Reuters had already warned before this week that bank earnings and inflation would be the two central pillars for measuring the strength of the rally and the path of rates. That is why a firmer Dow today does not mean total risk appetite; it means a search for relative refuge within equities.

Russell 2000: small caps, a real risk barometer

The Russell 2000 opens the session after closing Monday at 2,794.48 points, down 0.45%. This index is the best barometer for knowing whether the market is truly buying domestic growth or just rotating among giants. If the Russell moves higher too, the signal improves because it implies broader participation. If it lags behind, the message is more cautious: money is coming in, yes, but not with full conviction about the cycle. In a session marked by banks, imminent inflation data and doubts about technology, small caps may remain more erratic because of their greater sensitivity to financing costs and economic growth.

What it means for Spain and LatAm

For anyone trading in euros or dollars, this opening is immediately useful. At 3:30 p.m. Madrid time (8:30 a.m. Mexico City), Europe is still open, so the overlap between both sessions makes it possible to react in real time to the sector rotation in the United States. If you see Wall Street rewarding banks and punishing chips, that reading does not stay confined to New York: it spreads to ETFs, futures, ADRs and the closing sentiment in Europe. You do not need to duplicate your strategy by geography; you need to read sector leadership correctly.

The practical bridge is this: if your benchmark is in euros, today it matters to watch not only U.S. indices, but also the dollar, the yield curve and oil, because they shape the opening read and the cost of hedging positions. If your benchmark is in dollars, the focus is on not confusing a stable S&P 500 open with broad market strength. Today the bias is much more selective. A flat index with a weak Nasdaq and a strong Dow says the market is discriminating, not buying everything. That difference is what separates a session to chase price from a session to demand confirmation.

Stocks rising and falling the most at the open

Among the names showing the best tone at the open are Goldman Sachs, boosted by a positive reception to its results; UnitedHealth, which in pre-market trading was up around 2% after raising its 2026 earnings outlook; and, by extension, several major banks benefiting from the start of earnings season. The energy and defensive sectors are also arriving with a better relative tone because of the elevated crude backdrop and the search for less demanding valuations. Investing.com summarized in its daily coverage that the U.S. open was being shaped by bank earnings, inflation on the horizon and persistent pressure on technology.

On the weak side, the market is again pointing to semiconductors and names tied to massive AI spending. Nvidia is coming under technical pressure, while competitive noise in memory and chips continues to weigh on Nasdaq sentiment. JPMorgan was also showing a muted or negative reaction in pre-market despite remaining an absolute benchmark for the sector, because the market does not reward profits alone: it rewards a clear positive surprise. Wells Fargo was likewise showing a lukewarm reaction after beating on earnings, but missing on revenue according to the earlier market read. If you need one operational takeaway from this open, it is this: today the index is not in charge, sectors are; and within them, earnings and the credibility of guidance are in charge.
