The Ibovespa kicked off 2026 with a bang, rallying 1.76% to close at 163,000 points amid economic data releases and geopolitical tensions. Cogna (COGN3) stole the spotlight with a 17.57% weekly surge after bullish analyst upgrades, while C&A (CEAB3) crashed 13.05% on weak holiday traffic forecasts. Meanwhile, the U.S. dollar dipped 1.10% against the real, and Brazil’s IPCA inflation closed 2025 at 4.26%—within the central bank’s target range. Here’s your deep dive into the week’s financial rollercoaster.
Why Did Ibovespa Rally This Week?
The Brazilian benchmark index rode a wave of optimism, gaining 1.76% despite mixed signals. While domestic concerns like the Banco Master case lingered (more on that later), strong performances from education stocks and commodities offset jitters. The real also flexed its muscles, with USD/BRL falling to R$5.3658—a 1.10% weekly drop. Traders are now betting on a potential Selic rate cut by March, especially after December’s IPCA inflation print came in at a tame 0.33% monthly increase.
Cogna’s Meteoric Rise: What’s Driving COGN3?
Education giant Cogna (COGN3) skyrocketed 17.57% this week, becoming Ibovespa’s top performer. The rally began when JP Morgan upgraded the stock from "neutral" to "buy," slapping a R$6.50 price target for December 2026. Analysts Marcelo Santos and Livea Mizobata called its valuation "attractive" despite a 240% surge in 2025. UBS BB later tempered expectations, maintaining a "neutral" rating but acknowledging improved fundamentals. "The risk-reward balance now seems fairly priced," noted UBS analysts Andre Salles and team. Pro tip: When two major banks debate a stock’s worth, retail investors should watch the volume—COGN3 traded at 1.8x its 30-day average.

C&A’s Collapse: Why CEAB3 Crashed 13%
Retailer C&A (CEAB3) wore the week’s dunce cap, plunging 13.05% after UBS BB slashed its 2026 profit forecast by 10% to R$511 million. The culprit? Empty shopping malls during Christmas. "Foot traffic was worse than our worst-case scenario," admitted the bank’s report. While UBS kept its "buy" rating (with a lowered R$20 target), investors clearly weren’t convinced—CEAB3’s volume spiked to 2.3x average as sellers dominated. Fun fact: This marks C&A’s worst week since its 2024 supply-chain fiasco.
Geopolitical Shocks: U.S. Moves in Venezuela
Markets briefly shuddered when President TRUMP announced "productive" talks with Venezuela after military intervention. The twist? A promised US$100 billion in oil investments from American firms. Meanwhile, Greenland-gate escalated as Trump floated "all options" (read: potential invasion) to secure the icy territory. While Brazil’s market shrugged this off, oil-sensitive stocks like Petrobras (PETR4) saw unusual volatility.
Inflation Check: IPCA Ends 2025 at 4.26%
Brazil’s benchmark inflation index closed the year at 4.26%—comfortably within the central bank’s 3%±1.5% target. December’s 0.33% monthly rise (vs. 0.18% in November) barely moved the needle on rate-cut expectations. "This is the calmest inflation’s been since 2018’s 3.75%," noted BTCC analyst Thiago Silva. With 12-month inflation now at its lowest in eight years, traders are pricing in a 70% chance of a Selic cut by March.
Banco Master Saga: TCU Kicks the Can
In a plot twist, Brazil’s Federal Audit Court (TCU) postponed its Banco Master inspection to January 21 after the central bank appealed. Earlier, TCU president Vital do Rêgo clarified that any Master liquidation reversal WOULD fall to the Supreme Court (STF), not auditors. The delay keeps markets guessing—Master’s bonds still trade at 32 cents on the dollar.
FAQ: Your Burning Questions Answered
Will Cogna (COGN3) keep rising in 2026?
Analysts are split. JP Morgan’s R$6.50 target implies 30% upside, but UBS thinks most gains are already priced in. Watch for Q4 earnings on Feb 15.
Is C&A (CEAB3) a bargain after its crash?
UBS says "yes" (R$20 target), but weak consumer spending could linger. Technical support sits at R$14.50—a key level to watch.
How will Venezuela tensions affect Brazilian markets?
So far, minimal impact. But if U.S. sanctions expand, Petrobras (PETR4) could benefit from higher oil prices.
