iolite (also known as cordierite) is a crystal that changes color when pointed toward the sun, even on cloudy days. The Vikings discovered iolite’s unique property, using it as a compass, which allowed them to conquer the seas and cement their reputation as legendary seafarers.

On Value Investing

High-profile proponents of value investing, including Berkshire Hathaway chairman Warren Buffett, have argued that the essence of value investing is buying stocks at less than their intrinsic value.

The intrinsic value is the discounted value of all future distributions. The discount of the market price to the intrinsic value is what Benjamin Graham called the “margin of safety”.

Robert Leitz

is iolite’s sole owner and investment professional. Before iolite, he held positions at Glencore and various financial institutions, including TPG Credit (a hedge fund), Goldman Sachs’ European Special Situations Group, and KPMG Corporate Restructuring.

Robert graduated from the University of St. Gallen (HSG), Switzerland, with a Master of Science in Business Administration and Economics, and wrote his master’s thesis under the guidance of Prof. Eli Noam at Columbia University, New York.

Robert Leitz is a member of EO – Entrepreneurs’ Organization, the world’s most influential community of entrepreneurs.
