Here is a great link to what Wikipedia defines as Investor Relations.
Investor Relations (IR) is a strategic management responsibility that integrates finance, communication, marketing and securities law compliance to enable the most effective two-way communication between a company, the financial community, and other constituencies, which ultimately contributes to a company’s securities achieving fair valuation. (Adopted by the NIRI Board of Directors, March 2003.) The term describes the department of a company devoted to handling inquiries from shareholders and investors, as well as others who might be interested in a company’s stock or financial stability.
