Angukia investment bank has 3 employees. - A1 who is the broker. She executes buy and sell orders on behalf of Angukia's clients (corporate, high net worthy and raia).
- B1 is Angukia's proprietary trader. He buys and sells various instruments using Angukia's capital.
- Finally C1 is the investment banker. He advises Angukia's corporate clients on mergers, divestitures, acquisitions, financing and capital raising events (such as rights issues).
In the West you'd be told that there is a Chinese wall between the various activities that Angukia undertakes such that C1 and A1 never converse about the deals passing through their desks. You'd be told that if A1 received an order for 5% stake in a particular listed share, she'd never tell B1 who was thinking about selling the 1% stake that he had built up for Angukia.
This is ofcourse not possible.
In the developing stockmarkets like the NSE, where integrity may not be as established, it is essential that IBs not be part of the trading in the market.
