Basically, there are two types of banks that participate in the stock market- the investment banks and the commercial banks. Apart from the equity services, the investment banks also provide free commodity tips.
Investment Banks are financial entities that provide strategic advice to companies, governments, and others on their capital requirements and investment decisions and arrange the raising of such funds on terms that are most suitable to the company. Their activities include advisory services for business expansions, project financing, mergers and acquisition, investment valuation, among others. They charge a fee for their services. These banks are responsible for extending stock tips to their clients. Investment banks also deal with large investors and help them manage their portfolios across asset classes, products, and geographies.
Commercial Banks provide banking services of taking deposits, providing credit and enable payment services.

They also provide term financing for projects. For individuals and households, banks provide a secure infrastructure for holding their excess funds, making payments, accessing credit and financing facilities.
