Q2 2026 Earnings Season Surprises, but Itaú BBA Urges Caution on Stocks

The corporate earnings season for the second quarter of 2026 concluded with operational figures above expectations for a large portion of companies listed on the Brazilian stock exchange, revealing corporate resilience that caught many analysts by surprise. However, the optimism generated by these robust profits clashes with the immediate reaction of asset prices, raising a red flag regarding the sustainability of current valuations in an environment where the commercial dollar trades at R$ 5.20, registering a 2.23% increase over a 7-day window and accumulating a 0.96% rise over the last 30 days. This disconnect between solid corporate operational delivery and exchange rate volatility demands a cold reading of the stock market, separating short-term noise from actual corporate cash generation. This scenario of restrained euphoria adds to a macroeconomic outlook where the 12-month accumulated IPCA receded to 4.44%, showing an inflationary dynamic that, although under control, still requires attention from portfolio managers, while the Selic rate remains parked at contractionary levels of 14% per year. Crossing these data with recent analyses, it is clear that local investors navigate troubled waters where the point optimism of a quarterly balance sheet can mask broader structural fragilities. From the perspective of the tradition of value and margin of safety, the current moment is not for greedy buying based solely on recent profit enthusiasm, but rather for extreme patience to avoid paying dearly for assets that already embed unrealistic expectations of future growth. Risk asymmetry and market mood cycles teach us that when most analysts upwardly revise projections after a positive harvest of results, the window to capture bargains narrows drastically, making investors vulnerable to severe corrections if the exchange rate or fiscal scenario suffers unexpected reversals. The major risk lies in the fact that many stocks on the Brazilian exchange already price in a scenario of operational perfection, ignoring that the pressured exchange rate at R$ 5.20 makes imported inputs more expensive and could compress margins in upcoming quarterly disclosures. Projecting the 30, 90, and 180-day horizon, analysts forecast that stock volatility should increase as the market digests the real impact of the 4.44% accumulated inflation on consumer purchasing power and industrial costs.
