The Globe and Mail reports in its Monday edition that National Bank of Canada's National Bank Direct Brokerage (NBDB) gets a B+ grade in the newspaper's annual ranking of digital brokerages. The Globe's Rob Carrick writes that NBDB is the zero-commission broker that best meets the needs of investors who want not just a platform for buying and selling investments, but also tools for monitoring a portfolio and researching stocks and ETFs. Both the website and app are lean and clean, and there is plenty of Morningstar and National Bank Financial research on stocks to work through. The addition of the Wealth-Scope portfolio analysis tool rounds out NBDB's offering nicely. Evaluations in the Globe digital brokerage ranking are based on more than 100 factors, broken down into five categories: convenience and security, cost, the investing experience, tools, and services for retirees. TD Direct Investing took The Globe's top honours.
