In brief
The Ibovespa rose for the eighth straight session on August 28 and closed the week up about 2.7%, per Exame, Money Times and Bloomberg Línea — the year's longest winning streak, begun August 19, a day after the eleven-session losing run ended.
Friday's session saw a slight gain on a day marked by Jackson Hole speeches and the digestion of Brazil's weak jobs data, per CNN Brasil and Money Times. The dollar rose 0.66% to R$ 5.196, per Poder360.
The flow backdrop is contested: Seu Dinheiro points to R$ 3.2 billion in foreign inflows for the week, while InfoMoney records record foreign outflows for August as a whole — different windows on the same phenomenon, with no primary B3 source opened by press time.

Market read-through
For equities, eight gains and 2.7% on the week reflect rotation into local risk anchored on expected Selic cuts — IPCA-15 deflation and weak Caged in the same week supplied the macro fuel.
The streak's test comes from abroad: the Fed's hawkish Jackson Hole tone pressures the long end and the currency, and a globally stronger dollar could drain the flow that sustained the recovery.
Portfolio impact
01Rotation into local risk, anchored on Selic-cut bets after weak inflation and jobs data, sustained eight straight gains and 2.7% on the week.
Positive direction describes current momentum, not a forecast — the streak itself raises technical-pause odds.
What would change the view: Continuation depends on foreign flows and the hawkish Fed's impact; profit-taking after eight gains is an immediate risk.
Direction is an explanatory hypothesis, not a forecast or recommendation.
Next signals
What to watch
- Whether the streak survives Monday's reopen.
- B3's consolidated foreign-flow data for August.
- The Fed's Jackson Hole tone effect on long rates and FX.
- The August 31 Brazil-US tariff meeting.
Limits of the reporting
What remains uncertain
- Friday's exact move differs across reports (0.22% to 0.30%), and the weekly gain appears as 2.71% in registered sources and 3.06% in an unregistered one; the text uses the confirmed floor of about 2.7%.
- Foreign flows diverge by window: R$ 3.2 billion weekly inflows (Seu Dinheiro) coexist with record monthly outflows (InfoMoney); primary B3 data was not opened.
- Exact closing levels were not pinned by two full groups by press time.
