Yes, it is generally possible to transfer funds from another brokerage account in order to invest in Goldman Sachs mutual funds. The process usually involves transferring the cash or securities from your existing brokerage account to your new investment account that is set up for Goldman Sachs mutual funds. This can often be accomplished through a Direct Transfer of Assets, also known as an ACATS transfer.
It is important to check with both your current brokerage and the specific requirements of Goldman Sachs mutual funds, as each may have different procedures and forms that need to be completed. Additionally, potential fees or tax implications associated with transferring assets should be taken into consideration. For more specific details, including any paperwork required, it may be beneficial to refer to the current Goldman Sachs website for guidance or additional information on how to proceed with this type of transfer.
