Would you mind elaborating on what you're looking to achieve? The universe of all public companies globally is somewhere in the order of 140K strong. If you're looking to retrieve any kind fo data for such a vast universe of stocks, Eikon is not the right product for you. I suggest you consider one of Refinitiv Enterprise product offerings that can provide data retrieval service on an industrial scale. But if I misunderstood your question, would you mind clarifying what you're looking to achieve?
