As the guidance (https://github.com/Dewey-Data/SafeGraph-PublicCompanies) claims, neither SafeGraph nor Compustat provide historical ticker information (i.e. the ticker identified by each data source is the ticker as of a particular point in time.), then is there any method that we can use to lower down the mismatch rate when linking SafeGraph with Compustat? Is "Stock Symbol" the only identifier available? Thank you.
