Episode

The extreme

From the outside, nothing much: an index parked in the middle of the ruler, the kind of month that earns no headline. On the inside, the most violent change of tenants in months. Capital evicted the cyclicals all at once — the companies that breathe with the economy, retail, the credit-fed industry — and ran for what protects: raw material and brick. It was, in thirty days, a drop of a size the archive rarely records — the kind of shift that only happens when something in the market's mind has been rewritten. In numbers: the Cyclical/Non-Cyclical ratio sank from below its own average into territory the archive almost never visits; commodities in reais stretched over the IBOV to a rare height; IFIX/IBOV crossed from neutrality to above the average. Selic at 7.75%, the dollar at R$5.54. The regime closed at 46.6 — and told none of this.

What happened next

The internal renovation did not settle. Three months later, in January 2022, the flight from cyclicals reversed: the ratio finally crossed to the positive side of its own average, and the banks took the throne from the defensives — Financials/IBOV jumped from discount to a clear premium, while real estate funds and utilities lost everything they had. But the pendulum swung back. In April 2022, the defensives retook the top (IFIX/IBOV back from discount to premium; commodities in reais once again well above the average) and the cyclicals retreated once more. The same building, different floors — and the tenants never stopping their moves.

What did not happen

The general index never registered the violence: 46.6 is a quiet-month number, and anyone who read only the ceiling did not see the construction inside. The cyclicals' rare floor was not permanent either — in three months the ratio was already on the positive side. And the reading announced no direction: with the six-month horizon matured, the episode yielded −0.4%, below the central band of comparable outcomes (8.0% to 13.7%, median of 11.3%), outside the 80% band.

The honest verdict

The Radar caught the form — the sharpest sector rotation of the quarter — but the form carried no course. The renovation inside was real; what it promised was not. The return fit the month's own classification: ambiguity. An extreme move is not always a signal; sometimes it is just furniture changing places.
