The Big Three
The MSCI COLCAP slipped 0.39% to 2,169.52 on Monday — giving back roughly a quarter of Thursday’s +1.54% bounce — as the open at the session high (2,187.27) confirmed selling pressure from the first tick. The session low at 2,156.79 retested the March correction zone. The close at 2,169.52 sits between the 2026 low (2,141/2,145) and the lower Bollinger Band (2,211). RSI signal at 37.32 remains deeply oversold — recovering marginally from the 31.56 exhaustion but far from the 50 neutral line. The MACD histogram deepened to −26.11 from −23.32. The relief bounce from Thursday has not produced follow-through — but it has not been fully reversed either. The COLCAP is consolidating in the 2,141–2,187 range, waiting for the next polling signal.
The CNC poll released May 3 shows Petro’s approval dropping to 49.3% — the first reversal in three months (down from 50.9% in March) — while Cepeda leads the first-round race. The Petro approval slide arrives 27 days before the election and reverses the recovery that had taken his favorability above 50% for the first time since 2024. For the COLCAP, the Petro number matters less than the Cepeda positioning: a declining Petro approval could either drag Cepeda down (guilt by association) or liberate him (allowing him to differentiate from the incumbent). The Greens’ formal endorsement of Cepeda (April 24) — with the explicit condition of “defence of the 1991 Constitution” and reforms through Congress, not a constituent assembly — is the most important moderation signal from the Cepeda camp. If the Greens’ condition holds, a Cepeda presidency would govern within the existing institutional framework.
The three-way race’s alliance dynamics are crystallizing — and the right-wing split remains the COLCAP’s structural headwind. The Colombia elections digest reports that Cepeda’s deal with the Greens commits him to the 1991 Constitution while keeping the constituent assembly as a possible — but not primary — instrument. Valencia has secured the Conservative Party endorsement and La U has decided not to support Cepeda, but the right-wing magazine Semana ran a negative cover story questioning Valencia’s “anything goes” alliance strategy. De la Espriella has defiantly rejected institutional endorsements. The Cepeda campaign fears Valencia more than de la Espriella in a runoff — Valencia is seen as a moderate, calm alternative (a “Duque 2.0”) while de la Espriella is more easily portrayed as an extremist. For the COLCAP, the critical question is whether the right consolidates behind one candidate before May 31 — and the current dynamic suggests it will not.

02 Equities — Consolidation, Not Collapse
COLCAP Colombia today enters Tuesday’s session at 2,169.52 — inside the 2,141–2,187 consolidation range — after Monday’s −0.39% session gave back part of Thursday’s bounce without retesting the 2026 low. This Colombia stock market report covers a session where the market digested the Polymarket shift (Cepeda now the frontrunner at 42%), the Petro approval decline (49.3%), and the Greens’ endorsement of Cepeda with constitutional safeguards. The COLCAP’s muted response to these developments — neither a panic selloff nor a relief rally — suggests the market has already priced a competitive Cepeda candidacy. The −8% decline since April 16 was the repricing event. This is part of The Rio Times’ daily coverage of Latin American equity markets.
The Greens’ endorsement condition is the most underappreciated development of the past week. By explicitly requiring Cepeda to commit to the 1991 Constitution and reforms through Congress — not a constituent assembly — the Greens have established an institutional constraint on any Cepeda presidency. The constituent assembly was the market’s worst-case Cepeda scenario; the Greens’ condition makes it significantly less likely. The question is whether the market trusts this constraint. If it does, a Cepeda presidency within the existing institutional framework would be tolerable — not positive, but not the catastrophe the April selloff priced.
03 The Alliance Map — 26 Days Out
The election’s alliance dynamics have crystallized into a clear picture. Cepeda: Pacto Histórico base + Greens endorsement (condition: defend 1991 Constitution) + Petro’s May Day mobilization machine. His campaign promises “profound structural transformations” but within the institutional framework — a distinction from Petro’s constituent assembly push. His vice-presidential pick, Nasa indigenous senator Aida Quilcué, represents the social-movement base. Cepeda’s internal tension: Petro and the left push the constituent assembly; Cristo and the Greens oppose it. The Cepeda camp privately fears Valencia more than de la Espriella in a runoff.
Valencia: Democratic Center + Conservative Party endorsement + La U (declined to support Cepeda). Semana’s negative cover story (“anything goes” alliances) has dented her moderate image. Her vice-presidential pick, Juan Daniel Oviedo (1.25M primary votes), provides technocratic credibility. She is the “Duque 2.0” — moderate, calm, institutional — but the right-wing association with controversial figures limits her centrist appeal. De la Espriella: outsider populist, Bukele-style, rejected institutional endorsements, pledged to cancel peace talks and build megaprisons. His support is real but has a lower ceiling — the Cepeda camp would prefer to face him in a runoff. For the COLCAP, the math is simple: a consolidated right-wing candidate beats Cepeda; a split right-wing vote gives Cepeda the first round and potentially the runoff.
04 Key Levels
| Level | MSCI COLCAP |
| 200-day SMA | 2,225.02 |
| Lower BB | 2,211.19 |
| Monday Close | 2,169.52 |
| 2026 Low | 2,141.02 |
| Long-term trendline | ~2,068 |
05 Looking Ahead
Tuesday enters with the COLCAP consolidating in the 2,141–2,187 range. A close above 2,187 (Monday’s open/high) would be the first higher high since the bounce and would target the lower BB at 2,211. A close below 2,157 (Monday’s low) retests the 2026 low. The election (26 days) is the only variable that can produce a sustained directional move. Each poll, endorsement, and alliance shift will move the index in the final month.
Key dates: May 31 — Presidential first round (26 days). June 21 — Runoff. CNC poll: Petro 49.3% (dropping). Cepeda: frontrunner, Greens endorsed (no-assembly condition). Valencia: CD + Conservative + La U. De la Espriella: outsider, rejected endorsements.
06 Verdict
Monday was consolidation, not collapse. The −0.39% giveback from Thursday’s bounce — with the session low retesting the March correction zone at 2,157 but not breaking the 2026 low at 2,141 — suggests the market has found a temporary equilibrium near 2,170. The Petro approval drop to 49.3% introduces a new variable: declining presidential popularity 26 days before the election. The Greens’ endorsement condition (defend 1991 Constitution, no assembly) is the most constructive Cepeda signal for markets. If the market begins to price a Cepeda presidency constrained by the Greens’ institutional framework — rather than a Petro-style radical continuation — the downside from current levels may be limited.
Bias: Bearish — but the worst may be priced. The COLCAP at 2,170 has declined −7% from the April 16 high and is consolidating near 2026 lows. The Polymarket shift to Cepeda was the repricing event — and Monday’s muted −0.39% response suggests the market has absorbed it. The Greens’ no-assembly condition limits the tail risk of a Cepeda presidency. The right-wing split (Valencia vs de la Espriella) remains the structural obstacle to a COLCAP rally. The 2,141 low is the floor. The 200-SMA at 2,225 is the ceiling. Twenty-six days decide everything.
