Argentina Stock Market Falls 1.42% Hours Before April Inflation Release
The S&P Merval fell 1.42% to 2,792,993 on Tuesday May 12, 2026, giving back roughly half of Monday’s +2.31% capitulation-reversal rally. The index sits just above the double-tested capitulation floor at 2,749,913 ahead of Wednesday’s INDEC April CPI release at 16:00 Buenos Aires time. A sub-3% monthly print would be the first in 11 months and unlock 2,895,000; a third consecutive 3%+ print retests the capitulation zone.
The Big Three
The S&P Merval fell 1.42% to 2,792,993.25 on Tuesday — surrendering 40,127 points and giving back roughly half of Monday’s +2.31% reversal. Intraday range 2,784,435–2,850,174 with the close inside the lower third of the day. The index opened at 2,833,120 (the exact Kijun level reclaimed Monday), rallied briefly to 2,850,174 (close to the cloud top), then sold back through the entire upper Bollinger Band region to close just above the 50-day SMA at 2,818,246 — which is now overhead resistance, not support, per BYMA data as of the Tuesday close.
The technical structure has flipped from bullish reversal to neutral-pending. The MACD histogram improved marginally to −8,813 from −9,551, suggesting momentum is still recovering — but the MACD line at −18,365 versus signal at −9,551 remains in negative crossover. RSI fast at 45.59 with slow at 45.01 is firmly below the neutral 50 line with both indicators flat — the textbook reading of a market waiting for a binary catalyst. The double-tested capitulation floor at 2,749,913–2,754,976 sits just 38,000 points (1.4%) below Tuesday’s close. The ascending trendline from January at 2,603,419 is the deep macro support.
INDEC publishes the April CPI on Wednesday May 13 at 16:00 Buenos Aires time — the single binary catalyst for the next leg. The inflation trajectory has been: January +2.9%, February +2.9%, March +3.4% (annual 32.6%). The BCRA’s REM survey projects 2026 full-year at 29.1%; Moody’s Analytics expects approximately 28%. A reading below 3% would be the first sub-3% monthly print in 11 months and would confirm the March spike as seasonal — the bull case for the double-tested 2,750K floor to launch toward the cloud top at 2,895K and ultimately 3,000,000. A reading at or above 3% extends the disinflation plateau into an 11th consecutive month and retests the capitulation zone for a third time.

03Key Movers
Winners
Energy was the lone bright spot in a session dominated by pre-CPI de-risking. YPF traded firm on Brent’s overnight surge above US$108 — Argentina’s largest integrated energy company is the most direct beneficiary of the Iran-rejection trade. Pampa Energía (PAMP) and Vista Energy (VIST) also held on Vaca Muerta production tailwind narrative. Defensive consumer names — Mercado Libre (MELI) ADR equivalents, Cresud (CRES) — closed marginally green as institutional allocators rotated into the lowest-beta domestic exposures available.
Losers
The Milei-trade names led the retracement. Banco Macro (BMA), Grupo Galicia (GGAL), and BBVA Argentina (BBAR) — the highest-beta proxies for the disinflation thesis — gave back most of Monday’s gains as positioning unwound into the CPI binary. Telecom Argentina (TECO2) and Transportadora de Gas del Sur (TGS) followed the broader risk-off. The advance/decline ratio reversed entirely from Monday’s broad rally — Tuesday closed with roughly 80% of Merval components in the red, consistent with a clean de-risking session rather than fundamental rejection of the disinflation thesis.
§04 · Market Commentary
Tuesday was a textbook pre-binary positioning session. The Merval entered the day at the Kijun (2,833,120) after Monday’s +78,144-point reversal off the double-tested capitulation floor — the second such capitulation-and-reversal in seven sessions, on May 6 (low 2,749,913) and May 11 (low 2,754,976). That kind of structure usually produces consolidation into the next catalyst, not breakout extension. The catalyst is Wednesday’s INDEC CPI release for April at 16:00 Buenos Aires time, less than nine hours after this report’s snapshot at 06:48 UTC.
The disinflation trajectory under Milei has been the central pillar of the Merval’s 2024–2025 rally. Annual inflation collapsed from 211% in late 2023 to 32.6% YoY in March 2026. But the monthly trajectory has stalled in 2026: January +2.9%, February +2.9%, March +3.4%. Three consecutive 3%+ readings would shift the regime narrative from “decelerating toward single digits by 2027” to “structural plateau near 35%” — a thesis break the equity market cannot price out without an exchange-rate or policy shock. The PIIE explicitly warned last month that Argentina’s monetary framework “contains new vulnerabilities” tied to the band-based FX regime. Both Moody’s Analytics (28% full-year) and the BCRA’s REM survey (29.1%) still model deceleration, but the conviction has thinned.
The structural overlay supports patience. The World Bank projects Argentina growing 3.6% in 2026 — far above Brazil’s 1.6% or Mexico’s 1.3% — calling the country “the principal upside exception” in the region. The US$20 billion IMF Extended Fund Facility (US$12 billion disbursed) provides the funding backstop. The BCRA is buying approximately 5% of daily FX market volume to rebuild reserves. The Milei fiscal-surplus framework remains intact even as tax revenues underperform inflation for seven consecutive months. The bull case for the Merval is intact above 2,750,000. Wednesday’s print decides whether it gets tested for a third time or launches toward 2,895,000 and then 3 million.
05Technical Analysis
The Merval daily chart shows Tuesday’s bearish bar opening at 2,833,120 (Monday’s close, exactly the Kijun-sen) and closing at 2,792,993 — a clean rejection of the cloud bottom test. The intraday high at 2,850,174 reached the upper cloud region before sellers took control. The session candle is a long red bar inside the prior day’s range, the technical signature of a one-day-reversal rally that failed at first resistance. The 50-day SMA at 2,818,246 is now overhead resistance rather than dynamic support.
Momentum: The MACD histogram at −8,813 has improved from Friday’s −9,551 but remains below zero. The MACD line at −18,365 versus signal at −9,551 is in negative crossover with the signal line still curving down — momentum has not yet turned positive. RSI fast at 45.59 with slow at 45.01 — both indicators flat and below 50, the textbook setup for a market awaiting a binary catalyst rather than trending.
The double-tested capitulation floor at 2,749,913–2,754,976 is the single most important technical level on the chart. It has produced sharp intraday reversals on both May 6 and May 11. A third test below this level on a hot CPI Wednesday would be the most significant technical break of 2026 and would open the ascending trendline from January at 2,603,419 — over 7% below Tuesday’s close. Conversely, a sub-3% CPI launches from this floor toward 2,895,293 (upper cloud, +3.7%) and then 3,000,000 (psychological round number, +7.4%).

07Questions & Answers
Verdict
The Merval enters Wednesday session at 2,792,993 — between the failed Kijun reclaim at 2,833,120 and the double-tested capitulation floor at 2,749,913 — with the entire structure waiting on the INDEC April CPI release at 16:00 Buenos Aires time. The momentum picture (MACD still negative, RSI 45.59 / 45.01 below neutral) provides no directional signal independent of the data. The structural thesis (3.6% growth, IMF backstop, BCRA reserve build) remains intact regardless of the print. The trading question is binary: sub-3% launches toward 2,895K and 3,000,000; 3.5%+ retests 2,750K for a third time.
