The market that sold the banks to buy the barrel — February 2021

Episode

The extreme

From the outside, the month had no story to tell: domestic mood opened and closed at the same spot, stuck at neutral. On the inside, the market was doing the most aggressive thing it knows how to do — pick a side and abandon the other. Capital was selling banks to buy raw materials, and it did so with rising conviction. The relationship between commodities and the index stretched to a rare level; the relationship between banks and the index sank to the worst rung on the grid. An index that looked motionless was, in truth, balanced on a single leg. In numbers: Ânima pinned at 48.0 at the open and at the close, the Commodities (R$)/IBOV ratio jumping from 1.11 to 2.15 deviations, Financials/IBOV plunging from -1.65 to -2.44, and the Perene Risk axis giving way from 37.5 to 27.7 — back into aversion.

What happened next

The single bet did not survive its own intensity. In May, three months later, aggregate appetite surged — the Perene Risk hit 94.3 and Ânima entered extreme optimism at 84.6 — but the leadership holding it all up was already coming apart: the Cyclical/Non-Cyclical ratio collapsed from +0.41 to -1.09, and commodities gave way from +1.83 to +0.84. By August the hollowing-out was complete: the cyclical bloc touched the most depressed reading in the series, -1.87, and raw materials retreated to +0.44, with nothing to replace them. The reversal came a year later. In February 2022, the banks discarded at the bottom — Financials/IBOV at -2.44 — returned to the top, stretched to +2.54 deviations, leading the very index that twelve months earlier had cast them off.

What did not happen

The narrow leadership of commodities was not conviction — it was fragility disguised as strength. Anyone who read the jump to 2.15 deviations as the start of a reign got it wrong: the theme lost dominance within the following months. And the banks, thrown to the worst rung on the grid, did not stay at the bottom: within a year they were paying the highest premium in the index. The Perene Risk's drop into aversion also failed to bring the tumble it usually announces — the regime held.

The honest verdict

The reading caught the fragility of the concentration, but not the direction. The month itself matured six months later as a hit, with a return of +8.5% — only across eight comparable episodes and a wide dispersion, from -10.9% to +20.4%. The number landed in the good third of the cloud; the statistics had no basis to claim merit. The lesson that remains is a different one: an index propped up by a single leg deceives through its headline number, and the leg that looks strongest is rarely the one left standing.
