Tuesday, May 19, 2026 · Covering Monday May 18 session Summary

Merval Argentina today reflects Monday's 4.00% surge to 2,816,245.26, the biggest LatAm gain. The cloud floor at 2,700,961 held, the 200-DMA and 50-DMA were reclaimed in one candle. This is the third capitulation reversal of May after May 6 +4.42% and May 11 +2.31%.

The Big Three 1.
Merval closed Monday at 2,816,245.26 (+4.00%, +108,376 pts) - biggest LatAm gain (Mexico +0.63%, Brazil −0.17%, Colombia −0.98%). Open 2,709,579, low 2,703,512 (2,551 above the cloud bottom at 2,700,961), close near the high. Bullish marubozu. The third May capitulation reversal after May 6 (+4.42%) and May 11 (+2.31%). 2.
Friday's RSI fast 38.88 was the deepest oversold since the April lows. Both prior May tests at the 2,750K floor produced sharp reversals. Friday's break pulled the index to the cloud bottom and 200-DMA, where mechanical buyers re-entered. RSI recovered to 49.40. 3.
Monday reclaimed the 200-DMA (2,791,183), 50-DMA (2,795,565) and cloud top in one candle. MACD histogram improved from −14,627 to −8,001, narrowing materially. Structural pillars held: BCRA reserve build, US$20B Treasury swap, fiscal surplus. The Milei reform premium is tested, not broken.

Source: BYMA, BCRA, TradingView. Snapshot: May 19, 2026 06:21 UTC. 03 Why Argentina Reversed External Trigger: Warsh shock has no Monday follow-through

Friday's Warsh handover and US April CPI 3.8% drove the 10Y to 4.55% and broke the Merval through the 2,749,913 floor. Monday saw no follow-through: global yields stalled, dollar bid eased. Argentina took the biggest reversal because the drop was deepest - 19.8x forward P/E is the most leveraged in LatAm both ways.

Local Anchor: Structural pillars held the capitulation

The session low at 2,703,513 sat 2,551 above the cloud bottom - mechanical buyers had a clear line. Structural pillars held: BCRA reserves building toward the $10B target, US$20B Treasury swap backstop, fiscal surplus, soybean inflows through May. Country risk near 500bps remains the threshold for private-market access. Milei's October midterm mandate is not in question.

§04 · Market Commentary

Monday delivered the third capitulation reversal of May: May 6 (+4.42%), May 11 (+2.31%), May 18 (+4.00%). Each test pierced the prior floor by progressively more, each reversal sharper. Textbook absorption. The cloud bottom at 2,700,961 was the line; Friday's break was the buying opportunity, not the breakdown.

The session reclaimed the 200-DMA, 50-DMA and cloud top in one candle, closing at the 20-DMA cluster. Resistance overhead: Kijun (2,872,612), upper Bollinger (2,948,806). The 19.8x forward P/E is no longer the highest-multiple risk in LatAm; it is the relief trade. RSI 49.40 leaves room.

05 Technical Snapshot

S&P Merval daily, BYMA. TradingView · May 19, 2026 06:21 UTC

Merval closed Monday at 2,816,245 above the 200-DMA (2,791,184), 50-DMA (2,795,565) and cloud top (2,834,088 - close 17,843 below) reclaimed intraday. The 20-DMA cluster at 2,824,884 and Tenkan at 2,816,893 sit at the close. Session low 2,703,513 held the cloud bottom 2,700,961 by 2,551 points - a textbook mechanical floor. MACD histogram improved sharply from −14,627 Friday to −8,001. RSI fast 49.40, slow 44.31 - recovering from Friday's 38.88 oversold.

Resistance: 2,824,884 (20-DMA) → 2,834,088 (cloud top) → 2,872,612 (Kijun) Support: 2,795,565 (50-DMA) → 2,791,184 (200-DMA) → 2,700,961 (cloud floor) Invalidation: A daily close below 2,700,961 breaks the cloud and re-opens the lower Bollinger at 2,617,409. 06 Forward Look This week · Confirmation gate The Kijun at 2,872,612 is the confirmation. A close above unlocks the upper Bollinger at 2,948,806 and the path to 3M. A fade below 2,795,565 (50-DMA) classifies Monday as dead-cat. End May · Soybean window Peak harvest dollar inflows tail through May. BCRA reserve buying continues at ~$68M/day; June flows fade. June · Country risk watch A sustained move below 500bps unlocks private-market refinancing of the US$19B maturity wall. Above 500 keeps Argentina dependent on the swap line. June · May CPI print First sub-3% monthly print would revalidate disinflation thesis and unlock the Kijun-to-3M path. Tenth consecutive above-3% pulls relief off. 07 Questions & Answers Why did the Merval surge 4% Monday? Capitulation reversal. Friday's break of the 2,749,913 floor on the Warsh Fed shock pulled the Merval to the Ichimoku cloud bottom at 2,700,961, where mechanical buyers re-entered. Monday's session low at 2,703,513 sat 2,551 above the floor - a textbook test. The reversal reclaimed the 200-DMA, 50-DMA and cloud top in one candle. This is the third May capitulation reversal: May 6 +4.42%, May 11 +2.31%, May 18 +4.00%. Is the Milei reform premium safe? Held at structural support. The cloud bottom and 200-DMA cluster defined the post-October midterm uptrend. Friday pierced both intraday; Monday reclaimed both at the close. Fiscal surplus intact, BCRA reserve build at ~$68M/day, US$20B US Treasury swap backstop, soybean window still flowing. The premium was tested at its line, not broken. What confirms or fades Monday's reversal? The Kijun at 2,872,612 is the confirmation gate. A close above unlocks the upper Bollinger at 2,948,806 and reopens the 3M path. A fade back below the 50-DMA at 2,795,565 classifies Monday as a dead-cat bounce. RSI 49.40 leaves room either way; the next catalyst is the soybean window tail and the June country-risk reading. Verdict

Monday's +4.00% was the biggest single-session gain across LatAm and the third May capitulation reversal off the 2,700K cloud zone. Friday's break of the 2,749,913 floor created the buying opportunity, not the breakdown. The session reclaimed the 200-DMA, 50-DMA and cloud top in one candle. Structural pillars held - BCRA reserve build, US$20B swap, fiscal surplus, soybean window. RSI 49.40, MACD narrowing materially. The Kijun at 2,872,612 is the confirmation gate; cleared, the upper Bollinger at 2,948,806 reopens.

Related: Friday's floor break · May 11 double-test reversal · Mexico joins recovery camp.

Confirmation gate: Kijun at 2,872,612. Above = 3M path reopens; below 50-DMA at 2,795,565 = dead-cat.
