Comprehensive and Detailed Explanation From Exact Extract:

A joint account allows the husband to retain trading authority and includes the right of survivorship, ensuring the assets revert to him if his wife dies. The feedback from the document states:

"The husband would have no financial interest in a client name account, registered in his wife’s name only. A nominee account would transfer trading authority to a dealer or third-party administrator. In a tenants in common account, each spouse would have trading authority over his/her portion of the account. Therefore, the husband’s best option would be to open a joint account and retain full trading authority. A joint account would also offer the right of survivorship, which is not a feature of a tenants in common account."
