pension fund

Pooled-contributions from pension plans set up by employers, unions, or other organizations to provide for the employees' or members' retirement benefits. Pension funds are the largest investment blocks in most countries and dominate the stock markets where they invest. When managed by professional fund managers, they constitute the institutional investor category with insurance companies and investment trusts.
