...r each of the companies of the MSCI World Index between 2016 and 2021 ?

I am currently writing my Masters thesis and I would like to have access to this data to calculate the risk factors of the Fama-French 3 factor model. I know how to download them individually but I am trying to be time efficient here and downloaded them in one shot.

Hi @trstudent13 ,

May I advise reading the article 'Gathering aggregated ESG data on companies', especially its code on GitHub. An example of code you could use from this 'ESG_Boolean_Data' Python Class is:

tes0 = ESG_Boolean_Data(Value = "True", Antivalue = "False")
tes1 = tes0.get_data(Companies = ['0#.MIWO00000PUS'], # e.g.: SPX, MIWO00000PUS
    Fields = ['TR.AnalyticEnvControv','TR.EnvMaterialsSourcing','TR.EnvSupplyChainMgt','TR.PolicySustainablePackaging'],
    Static_fields = ['TR.HeadquartersCountry', 'TR.TRBCEconomicSector'])
tes1.df

Which will provide MSCI World Index companies' ESG boolean data outlined.

Otherwise, I must say that simply just constructing a banal eikon api call is the most efficient way to go about your request, e.g.:

df, err = ek.get_data(instruments=['0#.MIWO00000PUS'],  # This renders a list of all the companies in the MSCI world.
    fields=All_fields,
    parameters={'SDate' : '2020-01-01', 'EDate' : '2021-01-01', 'Frq' : 'FY'})

Note that - due to the naturally low frequency of ESG data publication - only annual ESG data points are considered reliable (and it most often is the highest frequency available for ESG data).

MSCI World is a large list of companies, you may thus hit eikon's data-request limit. I would advise using this technique to circumvent the issue - here it is used on Datastream calls, but it would work on eikon calls too.
