Is financial evidence in stocks accepted for a DTV in Berlin?

The query seeks clarification on whether financial evidence in the form of stocks is acceptable for obtaining a medical DTV visa in Thailand, given that the individual holds more than the required sum in stocks but not in a bank. Responses indicate that banks generally prefer bank balance statements, with a minimum of three months being necessary, and some suggest that having stocks could possibly strengthen the application but is unlikely to suffice on its own.
