We have already imported pandas as pd for you. We have also loaded both the historical price series of your index constituents into the variable stock_prices, and the index as index.

  • Inspect both index and stock_prices using .info().
  • Use .join() to combine index with stock_prices, and assign to data.
  • Apply .pct_change() to data and assign to returns.
  • Create pd.ExcelWriter and use with to export data and returns to excel with sheet_names of the same name.
