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 stretched to a level the archive rarely records, Financials/IBOV sinking even further below its own pattern, 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 the positive side to well below its own average, and commodities gave back much of their premium. By August the hollowing-out was complete: the cyclical bloc touched the most depressed reading in the archive, and raw materials retreated to near their own pattern, with nothing to replace them. The reversal came a year later. In February 2022, the banks discarded at the bottom returned to the top, stretched to an opposite and equally rare extreme, 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 that rare jump 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.
