Which type of brokerage firms will likely provide the lowest cost of buying selling and owning shares of a public company?

Discount brokerage firms typically offer the lowest costs for buying, selling, and owning shares of a public company. They charge lower commissions and fees compared to full-service brokerages, as they provide minimal personal investment advice and services. Additionally, many discount brokers have moved towards zero-commission trading, further reducing costs for investors. This makes them an attractive option for cost-conscious traders and long-term investors.
