One Rate Trade, Two Opposite Results on the Ibovespa

BRAZIL · MARKETS

The best and worst Ibovespa performers of the week were both supposed to be trading off the same interest rate curve.

One Rate Trade, Two Opposite Results on the Ibovespa

Assaí gained 8.15 percent over the week to 11 September and Direcional fell 8.64 percent, the best and worst performers in a week defined by an improving interest rate outlook.

The Week

August inflation came in at minus 0.32 percent, a deflation reading, and the curve moved in response. The central bank meets on 15 and 16 September with a fifth consecutive cut priced.

Assaí, the cash-and-carry food retailer, rose 8.15 percent. It carries significant debt and is one of the most directly rate-sensitive names in Brazilian retail, so an improving curve reduces its financing cost and its valuation discount at the same time.

Direcional, a homebuilder focused on the lower-income segment served by the Minha Casa Minha Vida programme, fell 8.64 percent.

Assai is one of the most directly rate-sensitive names in Brazilian retail.

Why They Diverged

Both are rate-sensitive, which makes the divergence the interesting part.

For a leveraged retailer, a falling curve is straightforwardly good. It cuts the interest bill and it lifts the multiple.

For a lower-income homebuilder the mechanism is different. Its buyers are financed through a subsidised programme rather than at market rates, so the policy rate matters less to demand than the programme’s funding does. What moves the shares is margin, land bank, and the terms on which units are sold.

JP Morgan cut its Direcional price target from R$19.00 (about US$3.73) to R$17.50 (about US$3.44) on a December 2027 horizon while keeping a buy rating, which is the standard shape of a house trimming expectations without changing its thesis.

Direcional builds for the subsidised lower-income housing segment.

What It Says About the Rally

Market commentary this week linked the broader Ibovespa move to election positioning, the so-called trade eleitoral, on expectations of gains for Flávio Bolsonaro and Augusto Cury.

The single-stock performance complicates that reading. A week where the leader is a leveraged grocer and the laggard is a subsidised-housing builder looks a great deal more like a rate story than a political one.

Both explanations can be partly right. Disentangling them from a single week of price action is not possible, and any account that presents one as settled is overstating what the data supports.

What Assai and Direcional Actually Do

Assaí operates atacarejó stores, the Brazilian cash-and-carry format that sells in bulk to small retailers, restaurants and price-sensitive households at the same time.

It expanded aggressively by converting hypermarkets acquired from the Casino group, and that expansion was debt-funded. Leverage is the reason its shares move so sharply on the rate curve.

Direcional builds for the lower-income segment served by Minha Casa Minha Vida, Brazil’s subsidised housing programme. Its units are financed through the FGTS severance fund at rates set by policy rather than by the market.

The two are therefore exposed to interest rates through completely different channels, which is the mechanical explanation for a week in which one led the index and the other trailed it.

What the Week Did Not Settle

Two stocks are two stocks. A week in which the extremes of the index are explicable by rate exposure does not establish that the whole move was a rate move.

The Ibovespa contains a large commodity block whose prices are set abroad and a banking block that gains from a steeper curve and loses from credit deterioration. Neither responds cleanly to the same signal as a leveraged grocer.

What the week does establish is that at least part of what has been described as election positioning has a simpler explanation available. That is worth saying because the alternative explanation is the one that gets repeated.
