Hi Vivek,
For the mutual fund investments in demat form, the AMCs generally are not able to generate and send you the statement. Even, when you enter your folio details on their website you would get an error saying that the folio or PAN does not match. But, when you call their customer care then they would confirm that the investments is valid and they will have your details.
However, some clients are able to generate the statement from the AMC website when they mention the folio details.
For the convenience of our customers who are investing in demat form, we have mentioned the procedure in this link through which you can generate your demat account statement. This statement reflect your investments in equities, mutual funds,bonds,etc.
