Yahoo Finance Portfolio Editor
Yahoo Finance Portfolio Editor allows for bulk updates of your portfolio from CSV files or direct input. It simplifies managing domestic stocks by enabling bulk registration of multiple stocks via CSV drag-and-drop or copy-and-paste from Money Forward ME asset pages. The tool is designed specifically for domestic stock management, offering options to set stock names, average acquisition prices, and quantities.
For those using Rakuten Securities or SBI Securities, the tool supports downloading holding stock CSV files. For Rakuten Securities, select "List of Owned Products" and click "Save as CSV." For SBI Securities, choose "Account Management," then the "Holding Securities" tab, and finally "CSV Download."
