Good businesses create value.
We seek businesses with durable competitive advantages, strong economics and the ability to compound value over long periods of time.

Investment philosophy
Knowledge compounds. So does capital.
Disagreement creates opportunity.
Consensus prices the obvious. Understanding sees what it misses. Judgment knows when the difference matters.
Valuation creates discipline.
Quality matters. Growth matters. But valuation determines the relationship between the price we pay and the value we receive.
Time allows compounding.
Compounding rewards patience and punishes interruption. Often the hardest decision is to do nothing.

Get in touchWhy Plympton Street
The name comes from Plympton Street near Harvard Yard, where a bookstore became part of the inspiration for how we think about investing.
Books turn information into knowledge. Knowledge improves judgment. Judgment builds conviction. Conviction, held consistently over time, can create wealth.
Plympton Street Capital is built around that idea: independent research, disciplined valuation and a long-term perspective.
