pynvest's Issues

[BUG]Extração de dados de Ações

✍️ Descrição do problema:

ToDo:

Ola @ThiagoPanini, tudo bem?
Inicialmente gostaria de parabenizar pelo seu trabalho nesse projeto, tenho estudado esse repositório e aprendido bastante!
estava analisando os dados extraídos e percebi um possível problema durante o processamento, ao realizar a extração de um ticker, alguns dados não parecem condizer com as informações disponiveis no site fundamentus, o estranho é que ocorre em alguns poucos cenários, não consegui ainda identificar o problema.

Algumas das colunas vem com a informação errada para ações específicas
Estou abrindo essa issue caso você acha valido investigar.

Criei uma classe de teste

from pynvest.scrappers.fundamentus import Fundamentus

fundamentus = Fundamentus()

teste = fundamentus.coleta_indicadores_de_ativo(ticker="AESL3")
teste.to_csv("./teste2.csv", index=False)

---

🐞 Reproduzindo o problema:

Para reproduzir o bug, siga os passos abaixo (exemplo):

1. Importar o módulo pynvest.scrappers.fundamentus
2. Executar a função coleta_indicadores_de_ativo()
3. Incluir os parâmetros (ticker ='AESL3')
4. Verificar a saída no csv gerado teste.to_csv

---

Fiz um de para dos campos, os que percebi que estão com problemas são esses aqui:
P/Ativos
P/Cap. Giro
P/Ativ Circ Liq
Div. Yield":
EV / EBITDA
EV / EBIT
Cres. Rec (5a)
