Brazilian Tickers

• IPCA.SA: Brazilian inflation index
• SELIC.SA: index that grows at the Brazilian base interest rate
• IMAB.SA: ANBIMA index of inflation-linked government bonds
• NTN-B.SA(YYYY): Brazilian government bonds (Tesouro Direto) with maturity year YYYY

B3 stocks, ETFs and REITs use the Yahoo format with the .SA suffix (e.g., PETR4.SA, see Yahoo). The platform also has its own codes for Brazilian indexes and bonds, all quoted in BRL:

• IPCA.SA: accumulated Broad Consumer Price Index (Índice Nacional de Preços ao Consumidor Amplo), the official Brazilian inflation measure. It starts at 100 on the first date, so its return is the inflation of the period.
• SELIC.SA: an index that starts at 100 and grows at the daily SELIC rate (Sistema Especial de Liquidação e Custódia), the base interest rate set by the Central Bank of Brazil. Use it as the Brazilian risk-free rate or as a proxy for post-fixed investments.
• IMAB.SA: the IMA-B index (Índice de Mercado ANBIMA), which tracks Brazilian government bonds linked to inflation.
• [TYPE].SA(YYYY): Brazilian government bonds with a maturity year YYYY. TYPE can be LFT, LTN, NTN-B, NTN-B-P, NTN-C, NTN-F, NTN-R or NTN-E (e.g., NTN-B.SA(2035) for the inflation-linked bond (Notas do Tesouro Nacional - Série B) that matures in 2035).

Combine these tickers with modifiers, e.g. SELIC.SA*1.1 for 110% of the SELIC rate, or IMAB.SA[|2020-12-31]+SELIC.SA[2021-01-01|] to chain two indexes over consecutive periods.
