Global equity markets opened the trading week with a cautiously optimistic tone, as investors navigated a dense calendar of macroeconomic catalysts alongside ongoing recalibrations in technology sector valuations. Following a period of consolidation in US indices, Monday’s opening bell delivered a measured risk-on signal, with institutional flows rotating into select high-conviction positions ahead of key data releases expected midweek. At mercados.lat, we analyze not just the opening numbers, but the underlying structural forces — from Federal Reserve policy signals to Latin American ADR momentum — that will define the week’s directional bias.
This edition of the Global Market Pulse covers the US equity landscape, the Magnificent Seven’s individual performance dynamics, the Latin American equity picture with emphasis on key ADRs, and a forward-looking assessment of the macro variables that will dominate market attention through the remainder of the week.
US Equity Indices: Opening Bell Analysis
S&P 500: Testing Resistance, Broadening Breadth
The S&P 500 opened Monday’s session with modest appreciation, testing the key technical resistance zone near its 20-day and 50-day moving averages following the prior week’s mixed performance. Importantly, market breadth indicators — notably the NYSE Advance/Decline line — showed early signs of broadening participation, with industrial, financial, and healthcare sectors contributing positively alongside the technology heavyweights. This breadth expansion is a constructive technical signal, suggesting the rally is not solely dependent on the Magnificent Seven for directional momentum.
The S&P 500’s resilience in recent weeks has been underpinned by three converging factors: (1) better-than-feared Q4 2025 earnings season results, with approximately 74% of S&P 500 companies beating consensus EPS estimates; (2) signals from the Federal Reserve that its monetary policy normalization path remains on track, with 1-2 cuts still anticipated for 2026; and (3) robust US labor market data (unemployment near 4.1%) that reduces near-term recession probability. According to Yahoo Finance market data, the S&P 500’s year-to-date performance through mid-March 2026 stands at approximately +7%, with significant dispersion across sectors.
Nasdaq 100: AI Capex Debate Weighs on Multiples
The Nasdaq 100 opened with a more cautious posture, reflecting ongoing institutional debate about the sustainability and near-term earnings impact of hyperscaler AI capital expenditure. The central concern among growth-oriented investors is whether the $300+ billion annual AI infrastructure investment by the major cloud providers (Microsoft Azure, Amazon AWS, Google Cloud) will generate sufficient near-term revenue acceleration to justify the capex drag on free cash flow. Until this tension resolves — likely through a series of strong cloud revenue acceleration reports — Nasdaq multiples may remain range-bound despite strong underlying earnings growth.
The Nasdaq 100’s sensitivity to yield curve dynamics remains elevated. Monday’s session opened with the 10-year US Treasury yield at approximately 4.40%, near the upper end of recent ranges, which maintains modest headwinds for the highest-multiple growth names in the index. A decline in yields toward 4.20% or below would likely trigger a meaningful re-rating of Nasdaq growth stocks.

The Magnificent Seven: Individual Performance Profiles
Leaders: NVIDIA and Microsoft
NVIDIA (NVDA) demonstrated relative strength in Monday’s opening session, continuing to benefit from the sustained enterprise demand for Blackwell GPU architecture and the announcement of additional sovereign AI partnerships in Europe and the Middle East. NVDA’s ability to maintain its price level near all-time highs — while broader Nasdaq names consolidate — reflects the market’s recognition that AI compute demand is structural, not cyclical. Institutional investors who missed the initial AI rally are still accumulating on any significant pullback.
Microsoft (MSFT) also opened with positive momentum, supported by continued news flow around Copilot enterprise adoption. Recent channel checks reported by technology analysts suggest that Copilot for Microsoft 365 seat counts are accelerating, with enterprise customers reporting meaningful productivity gains that justify the $30/seat/month premium. Azure’s re-acceleration to 31% growth in the most recent quarter has reinforced Microsoft’s position as the premier enterprise AI platform, and the market is pricing in continued outperformance relative to consensus.
Mixed Performance: Apple, Tesla, and Meta
Apple (AAPL) opened relatively flat, reflecting ongoing investor debate about the pace of the iPhone 17 upgrade cycle and Apple Intelligence adoption in key markets outside the United States. Services revenue growth (+14% YoY in the most recent quarter) provides a stable earnings anchor, but the stock requires a catalyst — likely the WWDC developer conference or a new product category announcement — to break out of its recent trading range above $220.
Tesla (TSLA) faced renewed scrutiny at Monday’s open, with investors focused on the latest Cybercab deployment timeline updates and Q1 2026 delivery numbers (expected to be released in early April). Analysts at Reuters have noted increasing competition from BYD in key international markets, particularly Europe and Southeast Asia, as a persistent headwind for Tesla’s automotive market share trajectory.
Meta Platforms (META) opened range-bound, digesting a strong Q4 2025 earnings beat while the market assesses the capital efficiency of Meta’s AI infrastructure investments. Meta’s $65 billion capex plan for 2026 — the largest in the company’s history — has divided investors between those who view it as essential AI competitive positioning and those who worry about margin compression and capital allocation discipline.
Cloud Giants: Alphabet and Amazon in Consolidation
Alphabet (GOOGL) and Amazon (AMZN) both opened in consolidation mode, reflecting the market’s wait-and-see posture ahead of their next quarterly earnings reports. For Alphabet, the key debate is whether AI overviews in Google Search are sustainably monetizable without eroding advertiser ROI or click-through rates. For Amazon, the focus is on AWS reacceleration evidence and the progression of its AI-powered logistics automation investments. Both stocks carry consensus analyst buy ratings with significant upside to price targets, suggesting the consolidation phase represents an accumulation opportunity for patient investors.
Latin American Equity Landscape: Key Highlights
MercadoLibre (MELI): Digital Commerce Resilience
MercadoLibre (MELI) — the region’s premier e-commerce and fintech platform — opened the week with notable institutional interest, reflecting continued confidence in the company’s dual flywheel of Mercado Libre marketplace growth and Mercado Pago fintech expansion. With over 220 million registered users and Mercado Pago processing total payment volume exceeding $200 billion annualized, MELI’s network effects are approaching the scale where competitive disruption becomes structurally difficult. The company’s Brazilian operations — its largest market — are benefiting from rising consumer spending and an accelerating shift from cash to digital payments, trends that remain in early innings relative to US or European markets.
Nu Holdings (NU): Digital Banking Scale
Nu Holdings (NU) opened with continued institutional confidence following its strong full-year 2025 results. Notably, Berkshire Hathaway fully exited its NU position in mid-2025, booking an estimated $250 million gain — a vote of discipline from the Oracle of Omaha rather than a verdict on the company’s fundamentals. With 110+ million customers across Brazil, Mexico, and Colombia, Nubank has become the world’s largest digital bank by customer count outside Asia. The company’s path to profitability — generating over $1.9 billion in net income for 2025 — has validated its business model against persistent skepticism about unit economics at scale. Monday’s session saw NU attract buying interest from institutional investors who view the stock as undervalued relative to comparable global fintech growth peers on a P/E-to-growth (PEG) ratio basis.
Vista Energy (VIST): Energy Sector Leadership
Vista Energy (VIST) — Argentina’s premier unconventional oil producer and a core holding in any serious LatAm portfolio — opened Monday’s session with constructive price action, tracking Brent crude’s stability and benefiting from continued positive news flow around Argentina’s fiscal reform progress. With VIST targeting 100,000 boe/d production by year-end 2026 and lifting costs among the lowest in the global upstream industry (~$5.50/boe), the company’s fundamental earnings power continues to be underappreciated relative to North American peers.
Vista’s exposure to the Vaca Muerta shale formation — a world-class unconventional resource with approximately 27 billion boe of technically recoverable reserves — provides a multi-decade growth runway that few emerging market energy companies can match.

Petrobras (PBR) and Vale (VALE): Commodity Heavyweights
Petrobras (PBR) opened Monday aligned with Brent crude’s modest positive bias, with investors watching the ongoing Brazilian government’s dividend policy discussions closely. Petrobras’s extraordinary dividend yield (trailing 12-month yield near 15% at current prices) continues to attract income-oriented institutional investors, though concerns about potential government interference in capital allocation decisions remain a persistent discount factor. Pre-salt deepwater production volumes remain at record highs, providing strong operational underpinning for the current dividend policy.
Vale (VALE) opened with mixed performance, reflecting the ongoing uncertainty around Chinese steel demand and iron ore import volumes. While Vale’s Q4 2025 production beat consensus estimates (achieving record iron ore shipments), the stock’s near-term trajectory will largely be determined by the trajectory of China’s property sector recovery — which, while showing early signs of stabilization, has not yet generated the demand reacceleration that would support a significant iron ore price rally above current $100/tonne levels.
Macro Calendar: Key Events for the Week
Investors should monitor the following high-impact macro events expected throughout the trading week:
- US CPI Inflation Release (Wednesday): The February CPI print is the week’s most critical data point. Consensus expects headline CPI at +0.3% month-over-month (+2.9% YoY), with core CPI at +0.3% (+3.2% YoY). A surprise to the upside would likely trigger USD strengthening and EM selling; a downside surprise would support Fed cut expectations and benefit LatAm risk assets.
- US Retail Sales (Friday): February retail sales data will provide a read on the US consumer’s resilience following the prior month’s weather-impacted decline. Strong data supports the “soft landing” narrative; weak data raises recession concerns.
- Federal Reserve Speaker Appearances: Multiple FOMC members are scheduled to speak throughout the week, providing potential market-moving commentary on the rate path and inflation assessment.
- Argentina’s Monthly Trade Data: Argentina’s trade surplus figures — a key input for evaluating BCRA (Banco Central de la República Argentina) reserve accumulation progress — will be watched by Argentine ADR investors for signals on fiscal reform continuity.
- Brazil Selic Rate Decision (COPOM): The BCB’s Monetary Policy Committee is expected to maintain its current Selic rate at 10.50%, though the accompanying statement’s tone regarding future cuts will drive BRL and Brazilian equity movement.
Cross-Asset Overview: Currencies, Rates, and Commodities
USD and DXY
The US Dollar Index (DXY) opened Monday near 103.5, within the broad range that has characterized the past three months. A DXY sustained above 105 would create headwinds for LatAm currencies and reduce EM attractiveness; a break below 102 would likely catalyze significant EM inflows. The near-term DXY trajectory hinges primarily on this week’s CPI print and its implications for Fed rate cut timing.
Brent Crude and Energy Markets
Brent crude opened the week near $82 per barrel, supported by OPEC+ production discipline and ongoing Middle East supply risk premiums. For Vista Energy and other Vaca Muerta producers, Brent above $75 ensures robust economics and supports continued capital deployment into growth drilling programs.
US Treasury Yields
The 10-year US Treasury yield’s behavior will be central to Monday’s trading dynamics. A yield decline toward 4.25-4.30% would be broadly constructive for high-multiple growth names (Nasdaq, MELI, NU); a move above 4.50% would likely pressure these same names and potentially trigger DXY strengthening.
Strategic Outlook: What to Watch This Week
The week ahead presents a binary risk scenario anchored to Wednesday’s CPI release. A benign inflation print would confirm the disinflationary trend and likely push S&P 500 toward new highs, with LatAm risk assets benefiting disproportionately. An upside inflation surprise would reignite “higher for longer” Fed concerns, strengthen the DXY, and create headwinds for EM capital flows.
Our base case remains constructive for both US equities and select LatAm names. The combination of resilient US earnings, moderate inflation trends, and Argentina/Brazil-specific catalysts supports a portfolio positioned for continued alpha generation in high-conviction LatAm plays (VIST, MELI, NU, GGAL) alongside core US equity exposure through the Magnificent Seven theme.
