When analysing data for investments, for example gold investment purchases. Is it permissible to include analysis of the gold futures market?
Another example could be a halal screened ETF that has a high correlation to a general stock index (containing haram investments) analysis can be performed on the general index with a predicted range for the ETF.
I am saying specifically that no purchase of haram investments are made, but that decisions on halal investments could be made on the analysis of data from haram markets.
Is this permissible?
Thanks very much inshallah.
