- The cause of the drop: Meta reported an increase in capital expenditures for AI, rekindling fears that financial returns will take longer than projected.
- The damage to indices: The Nasdaq plummeted 2.60% and the S&P 500 fell 1.21%, while semiconductor stocks like AMD (-8.10%) and Intel (-8.05%) suffered heavy liquidations.
- The effect on local investors: Holders of technology BDRs and New York-focused ETFs felt downward price pressure, partially cushioned by the dollar rising to R$ 5.03 in the domestic market.
The bill for multibillion-dollar investments in artificial intelligence has once again spooked Wall Street. Meta's upward revision of its capex projections proved that the financial market has lost patience with promises lacking short-term returns, triggering a wave of selling that heavily knocked down shares of tech giants.
Why did the Nasdaq and tech stocks fall on Wall Street?
The 2.60% drop in the Nasdaq stock index came after Meta confirmed higher capital expenditure estimates dedicated to artificial intelligence infrastructure. The news renewed immediate doubts among New York analysts regarding the actual speed at which these monumental outlays will translate into profits for shareholders.
The chain reaction was immediate. Meta saw its shares crash 6.98% in trading, contaminating the entire technology complex. The move exposed the vulnerability of stocks that had been trading at stretched multiples sustained solely by the artificial intelligence thesis.
The market's reading shifted gears. While in previous quarters any announcement of AI investment generated instant optimism, the current stance demands a clear demonstration of margins and cash flow. Without this tangible counterpart, high capex dependency has become synonymous with operational risk.
The contrast between the indices highlights a clear sector rotation. While technology companies weighed on the S&P 500 and the Nasdaq, the Dow Jones managed to close with a slight gain of 0.02%, boosted by the appreciation of defensive and traditional stocks such as Procter & Gamble, which advanced 5.58% after publishing its quarterly numbers.
Which stocks were hit hardest by the artificial intelligence sell-off?
Chip manufacturers and semiconductor companies led the day's losses in New York, driven by the view that infrastructure spending by large technology platforms may face revisions or margin pressure. Marvell Technology suffered the largest decline in the group, plummeting 8.70%, closely followed by AMD, which dropped 8.10%.
Not even the absolute leader of the sector escaped the bloodbath. Nvidia recorded a 4.40% pullback in the session, while Intel retreated 8.05% and Micron Technology fell 6.26%. The tumble laid bare how the fear of a slowdown in the hardware purchasing cycle impacts the supply chain from end to end.
Outside the direct chip ecosystem, Tesla fell 3.08% under the impact of the market's reaction to its earnings and an unfavorable environment for growth stocks. The dominant assessment on Wall Street is that tolerance for stretched valuations has reached its limit, requiring flawless operational execution to justify every multiple point.
How did the foreign exchange market and global fixed income react to the tech scare?
The flight to safety led investors to increase positions in defensive assets, prompting a drop in U.S. Treasury yields and a sharp appreciation of the yen against the dollar. The U.S. currency eased to 156.85 yen, while the DXY index retreated 0.17%, trading at 101.607 points.
Risk aversion was not limited to New York. In Europe, fiscal uncertainties in France and escalating local protests pressured the euro against the dollar, trading at $1.1218, while the pound advanced to $1.3397. At the same time, the surge in oil to its highest level in more than five months added apprehension regarding the trajectory of global inflation.
An analysis published by Swissquote pointed out that the rotation of investments out of the technology sector is likely to continue in the short term. However, the bank noted that artificial intelligence remains the central engine of long-term structural growth, emphasizing that tech stocks still retain the highest recovery potential in the market once volatility settles.
What does this mean for those investing in Brazil via BDRs, ETFs, or the dollar?
External turbulence hit assets traded on the B3 with direct exposure to the U.S. market squarely. Holders of big tech BDRs experienced sharp devaluations in local trading, in line with the movement in New York, which also affected the pricing of popular global equity ETFs, such as those linked to the S&P 500 and the Nasdaq.
If you hold international technology assets in your portfolio, the recent tumble reflects a repricing of expectations regarding return timelines, rather than the ruin of the structural thesis. The appreciation of the dollar in Brazil—trading in the R$ 5.03 to R$ 5.04 range during the day—acted as a partial cushion on wealth converted into reais, reducing the gross impact of Wall Street stock drops.
On the domestic front, the Ibovespa closed lower, pressured both by international risk aversion and local factors, including movement in banking sector stocks and Vale. The appreciation of the American currency against the real reflected the cautious stance of global investors amid a turbulent external environment and local events on the radar.
What should we monitor going forward in the U.S. stock markets?
The third-quarter earnings season is entering its most critical phase. Investors' focus is shifting away from current earnings per share alone and turning strictly toward capital discipline and companies' ability to monetize their technology projects.
Big Tech capex projections — Monitor whether other tech giants signal further upward revisions in infrastructure spending or indicate cost controls.
Signs of effective monetization — Follow the emergence of direct revenues from AI-based products and services that prove the return on investment made.
Treasury yield curve and commodities — Pay attention to the behavior of U.S. bonds and oil prices, which dictate global liquidity and risk appetite.
The shock caused by Meta on the Nasdaq shows that the financial market has traded fascination for a demand for concrete results in artificial intelligence. For those investing with a long-term focus via BDRs or ETFs, the moment calls for calm and discipline: panic selling usually crystallizes losses during correction windows that are strictly priced in by the market.
