Investment Strategy
PineStone employs a specialist, long-term global equity strategy, focusing on identifying and investing in what it believes are the highest quality companies (so-called quality compounders) worldwide and holding them for as long as possible—often decades. This 'actively patient' approach emphasizes deep fundamental research, alignment with client interests (through ownership and investment alongside clients), and a commitment to value creation over the long term. The strategy pursues superior shareholder value by concentrating on companies with durable competitive advantages and the capacity to generate sustained growth. The firm avoids unnecessary trading and instead seeks to benefit from compounding returns in leading businesses.
