When I query the SPSUPX (SP1500) it returns only 1291 lines; is this normal?
import eikon as ek import csv # Constituents SP1500
index = '.SPSUPX'
constituents, err = ek.get_data(index, fields= ['TR.IndexConstituentRIC','TR.IndexConstituentName'])
constituents.to_csv('SP1500.csv', sep=';', index=False)
