Saurabh Mukherjea, founder and chief investment officer of Marcellus Investment Managers, is a strong advocate of this approach in India. He emphasises investing in high-quality businesses with a sustainable edge and holding them for the long term. To meet the coffee can criteria, companies must:
- Have existed for more than 10 years
- Have a market cap above ₹100 crore
- Deliver more than 10% annual profit growth
- Maintain a return on capital employed (ROCE) of more than 15% over a decade
- Have a strong competitive advantage
In this article, we will look at five small cap companies that are aligned with Saurabh Mukherjee’s coffee can criteria.
