S&P 500 and Nasdaq: opening and first moves

S&P 500 today starts with a weaker tone than many hoped to see after Wednesday’s hit. At 15:30 Madrid (8:30 Mexico City), Wall Street’s benchmark opened with a bearish bias after futures had already pointed to continued pressure on technology and semiconductors. The previous close for the S&P 500 was 7,718.94 points, after falling 1.11% on October 14, and Thursday, October 15 futures were down before the bell, with the market still digesting hotter-than-expected inflation and the risk of higher rates for longer. Reuters reported before the open that S&P 500 futures were down 0.35% and Nasdaq 100 futures more than 1%. Reuters on Yahoo Finance and Yahoo Finance agreed that the focus was clearly on the punishment of the AI and chip ecosystem.

The Nasdaq 100, therefore, came into the open as the most sensitive index of the day. And that is no small detail: when Nasdaq 100 futures fall more than 1% while the Dow holds up better, the message is a defensive rotation within U.S. equities. The market is penalizing duration, stretched multiples and companies that rely on abundant financing to sustain investment in data centers and artificial intelligence. The useful read for investors is not just that “technology is falling,” but why it is falling: the implicit cost of capital is rising, tolerance for stretched valuations is worsening, and even a good result, such as TSMC’s, is no longer enough if it also comes with caution about 2027.

Dow Jones: better relative resilience amid the tech storm

The Dow Jones was coming into Thursday, October 15, more stable. On Wednesday it closed at 51,621.48 points, with a much milder decline of 0.09%, far from the damage seen in the Nasdaq and Russell 2000. Before today’s bell, Dow Jones futures were up 0.36%, a clear sign that money was seeking relative refuge in names less exposed to the semiconductor cycle and the AI financing narrative. That contrast matters a lot: this is not a blind liquidation of the entire stock market, but rather a session in which the market is discriminating among sectors and punishing most where the leverage to expectations was greatest.

What is moving the Dow today? Two forces. First, the digestion of September inflation in the U.S., which revived fears that the Federal Reserve may keep a restrictive tone. Second, bank earnings season, which continues to deliver mixed headlines. When macro pressure intensifies, the Dow often acts as a barometer of the broad market’s resilience. If it holds up better than the Nasdaq, the signal is not bullish by itself, but it does reduce the likelihood of indiscriminate panic. For intraday or swing traders, this means carefully separating which part of the market is breaking down and which is simply correcting less.

Russell 2000: small caps suffer again as rates remain elevated

The Russell 2000 came into this session after closing Wednesday at 2,729.53 points, down 1.9%. That already tells you where another sensitive area of the market is: small caps. If inflation surprises to the upside and fears of tighter policy rise, smaller companies tend to suffer more because they usually depend more on financing costs and have less operating flexibility than megacaps. So, even though the day’s headlines may go to Nvidia, TSMC or CoreWeave, it is worth watching the Russell 2000: if it opens weak again, that confirms the problem is not only technology, but tighter financial conditions for the market as a whole.

What this means for Spain and LatAm

For those following the open from Europe, the operational key is the overlap between the Madrid afternoon and the real start of New York trading. At 15:30 Madrid (8:30 Mexico City), Wall Street officially opens, and that first stretch often redefines how many European assets exposed to global risk close: banks, luxury, technology, industrials and also EUR/USD. If the Nasdaq opens clearly worse than the Dow, the message for euro-denominated portfolios is direct: the headwind is in growth and technology, while the defensive bias gains weight.

For LatAm, the reading is similar but with another tactical advantage: the U.S. session opens right in the morning, which allows a faster reaction in the first hour. If the market keeps punishing chips and small caps, it is worth watching not only indices, but also the dollar, yields and commodities. A higher-for-longer rate environment usually tightens global financial conditions and makes it more expensive to pay too much for growth. Put simply: today it is not enough to buy quality; you have to buy it at the right price.

Stocks rising and falling the most at the open

Among the standout moves ahead of the open, pressure remained concentrated in semiconductors and names tied to capital-intensive AI investment. Nvidia was down around 1.8% before the open, while AMD was down as much as 5.73%, Western Digital more than 4% and Seagate also more than 4%, according to data collected by Investing.com. CoreWeave remained at the center of the selloff, with a decline of nearly 4.5% in premarket after plunging more than 15% on Wednesday. Oracle also came under pressure, with a drop of close to 2% before the bell, extending the damage from the previous session. The premarket coverage from Investing.com made it clear that the market was still questioning the sustainability of spending and debt linked to the AI boom.

On the upside, Kimberly-Clark was up around 1.8% after reporting better-than-expected preliminary third-quarter figures, while Walmart showed gains of around 3.46% and Commercial Metals had a positive tone. There is an important lesson here: in an open dominated by rate fears and tech selling, money looks for visible profits, more defensive businesses and lower dependence on aggressive financing. Among the weakest names at the open were AMD, Western Digital and CoreWeave; among the best holding or rising names were Kimberly-Clark, Walmart and Commercial Metals. That dispersion is exactly what you need to read today: this is not a market for autopilot, it is a market for surgical selection.
