In a new partnership with publishers Harriman House, Share Radio has produced its first audiobook 'Superinvestors', written by Matthew Partridge and read by some of Share Radio's best known presenters. 'Superinvestors' lays bare the investing secrets of legendary investors - from early 20th-century figures such as Benjamin Graham and John Maynard Keynes, through to more modern names such as Anthony Bolton and Warren Buffett.
