Bank of America upgraded Magazine Luiza (MGLU3) from underperform to buy on Tuesday (11/10), pointing to an acceleration in October sales and the room opened by Casas Bahia's distress. The stock responded with a nearly 9% gain in trading, reaching R$ 6.39—the top performer on the Ibovespa for the day.
MGLU3 Today: Why Did the Stock Rally?
Bank of America (BofA) reversed its stance on MGLU3 from underperform to buy, maintaining its R$ 11 price target. The stock climbed nearly 9% in Tuesday's session (11/10) to close at R$ 6.39, leading the Ibovespa.
It was not a gradual adjustment: BofA jumped from its most negative rating to its most positive in a single move, known on Wall Street as a double upgrade. For a bank that was bearish on the stock prior to the elections, the pivot signals that the operational environment has improved enough to completely invert its outlook.
What Persuaded the Bank: October's Sales Acceleration
BofA's core argument rests on accelerating sales in October. Magalu's brick-and-mortar stores grew 16% compared to October 2025, up from +12% in September and +8% over the first eight months of the year. In its first-party (1P) e-commerce channel, the turnaround was even more pronounced: moving from a cumulative decline of 12% between January and August to a 14% increase in October, after passing through +5% in September.
Magalu reported this acceleration in a material fact filing on November 9, citing a "significant change in the competitive dynamics of durable goods retail." BofA considered the stock's decline in preceding weeks exaggerated relative to the operational improvement, creating an entry window. Our analysis of the October preliminary figures detailed how physical stores and the 1P channel converged on a simultaneous turnaround for the first time this year.
The bank also highlighted Magalu's entry into marketplaces like Shopee and Mercado Livre as a way to expand its reach without the cost of opening new stores. These partnerships allow Magalu to sell on established traffic platforms, capturing demand that previously went elsewhere. For BofA, this move increases market share capture without requiring additional capital expenditure.
How Casas Bahia's Retrenchment Reshaped the Sector
BofA's thesis relies heavily on the vacuum left by Grupo Casas Bahia (BHIA3). The company filed for judicial reorganization over the course of 2026 and closed roughly 300 stores, nearly 30% of its total footprint. According to Itaú BBA, two-thirds of those shuttered units had a Magalu store less than 400 meters away.
Chief Financial Officer Roberto Bellissimo stated that there is a 75% overlap with closed stores and 92% with remaining locations. This indicates Casas Bahia's restructuring still has chapters ahead, and every additional store that goes dark represents customer flow that must find a new destination. Itaú BBA estimates Magalu could capture R$ 3.6 billion in additional annual sales by 2027 simply through sector consolidation, without needing extra working capital.
"The micro will save the macro."Fred Trajano, CEO of Magazine Luiza, following 3Q26 results
The quote summarizes the operational thesis: individual market share gains can more than offset a challenging macroeconomic backdrop of high interest rates, squeezed consumption, and fragile consumer confidence. It is a directional bet that Magalu can grow while the sector contracts around it. Our 3Q26 earnings analysis showed the EBITDA margin reached 8.1% and net debt stood at 1.02x EBITDA—a manageable level, but one that leaves little room for error.
What Still Weighs: Fundamentals the Upgrade Does Not Fix
BofA's rating change did not alter the company's balance sheet metrics. Magalu's interest coverage ratio sits at 0.82x, meaning financial expenses consume more than the entire operating result—a growing risk while the Selic rate remains elevated. Earnings per share have fallen by 41% annually in real terms over the last five years, and median ROE sits at 1.0%, placing it in the weakest quartile of our corporate database.
BofA itself cut its 2026 earnings per share forecast from R$ 0.22 to R$ 0.13 in the same report announcing the upgrade. This contradiction is deliberate: the bank believes in the medium-term thesis, but acknowledges this year's numbers remain weak. With the stock at R$ 6.39, its P/E ratio stands above 50 times adjusted earnings—expensive for a company with the historical profitability shown in the data.
- Acceleration in brick-and-mortar sales and e-commerce recovery in October—clear recovery trajectory
- Competitive vacuum with 300 Casas Bahia stores closed (75% overlap with Magalu)
- BofA and BTG Pactual maintaining buy ratings; net debt down ~29% over the last twelve months
- Interest coverage of 0.82x—financial expenses exceed operating income
- Median ROE of 1.0% and ROIC of 3.2% over the past five years—weak historical profitability
- BofA cut 2026 EPS from R$ 0.22 to R$ 0.13 in the upgrade report
- Goldman Sachs, Santander, and UBS BB remain neutral and did not follow the pivot
Our valuation methodology calculates fair value at R$ 4.91—below the current market price—with negative margin of safety prior to yesterday's jump. An "avoid" verdict does not change because of one bank's note; it changes when the balance sheet improves. Months ago, Citi's downgrade caused the reverse move, sending the stock lower. Both moves in opposite directions show that MGLU3 is sensitive to large bank recommendations, creating volatility rather than necessarily creating value.
Existing MGLU3 unitholders saw welcome relief yesterday as the share price rose and a major bank reversed a negative stance. However, the upgrade does not resolve cash flow pressure from interest expenses or lift 2026 earnings—BofA halved its EPS forecast while raising its rating. For new investors, the entry point is higher than it was last week (R$ 6.39 versus R$ 5.84 on Monday). The bank's price target depends on October's acceleration proving to be sustainable rather than a peak, and on the Selic rate easing before cash runs out.
4Q26 Results — If brick-and-mortar stores sustain growth above +10% and e-commerce turns positive, the bank's thesis gains concrete footing. If metrics revert to August levels (+8% physical, negative e-commerce), the upgrade loses its central argument. Results are scheduled for release in February 2027.
Selic Rate — With an interest coverage ratio of 0.82x, any maintenance or hike in the Selic rate pressures cash and compresses operating margins. The bank's price target is more plausible in a declining interest rate environment than in the current setting.
Casas Bahia — Market share gains depend on the continuation of its distress. If the judicial reorganization stabilizes and stores reopen, part of the customer flow that migrated to Magalu could disperse throughout 2027.
