Separating Signal from Narrative

Concentrated quality, built to compound. Own fewer. Know more. Hold longer.

Research-Driven Conviction Builds Lasting Value

Peckham Capital Management is a fundamental investment firm built on a simple premise: own fewer businesses, know them more deeply, and hold them longer than most investors can. We invest where the market is mispricing quality, duration, or earnings power, and we underwrite every position to a clear view of long-term value.

Read Our Philosophy

“We spent over a decade compounding judgment inside BlackRock and T. Rowe Price, then built the research operation we always wanted: specialist desks working our playbook every day, challenging every holding we own. Judgment trains the machine, and the machine extends the judgment. The process, like the portfolio, is built to compound.”

William McSweeney, Co-Founder & CIO
Fascinated by markets from an early age. He bought his first stock at 12 because he loved his iPod. That curiosity never left. Built his first three-statement model at 15, spent over a decade at BlackRock and T. Rowe Price, and founded Peckham to invest the way he always believed it should be done.

01

Empirical Observation

Years of studying exceptional businesses, written down into a playbook: what quality looks like, where it hides, and what kills it. We start our research where the odds have most reliably been best.

02

Deep Fundamental Research

Deep bottom-up research builds differentiated insight through industry mapping, management assessment, and financial modeling.

03

Variant Insight

Every position reflects a view the market hasn't priced, whether on duration of growth, normalized earnings, or an emerging business trajectory.

04

Disciplined Underwriting

Entry, sizing, and exit are each anchored to a clear view of long-term value and required return. Conviction is earned through process, not narrative.

05

Continuous Validation

Kill conditions are set when a position is opened and monitored daily, not revisited annually. Positions are held for the right reasons, and exited with discipline when the thesis breaks.

Investment Philosophy

Three Baskets, One Book

Two engines drive the portfolio: a systematic discipline that surfaces compounders, and idiosyncratic work in the dislocations a screen never finds. Together they fill three baskets. Select one to see how we approach it.

Compounder Core

World-class businesses with defensive growth, high returns on capital, and long reinvestment runways. The market consistently underestimates the duration of their growth, so we hold where others trim. The core compounds quietly.

EdgeDuration of growth
HorizonMulti-year
MispricingQuality & duration

Next-Gen Compounders

Earlier-cycle businesses with advantaged economics, expanding moats, and S-curve adoption ahead of them. Consensus misses the non-linear path; we size in before the inflection is obvious. The next generation adds duration to the book.

EdgeAdoption curve
HorizonEmerging
MispricingTrajectory

Value & Special Situations

Forced sellers, orphan spin-offs, depressed cyclicals, and misunderstood breakups, found by pattern recognition rather than a screen. Richest exactly when growth is out of favor, these positions add asymmetry when someone else has to sell.

Why Peckham

A Rare Combination at Any Scale

Why This Strategy

Most quality frameworks are subjective. Ours is written down: a moat taxonomy with signatures and failure modes, screens that focus research hours where the odds are best, and a process that grades its own predictions. We go where pure-quality managers won't: into value and cyclical situations where our edge is sharpest.

Why This Team

Over a decade of analyst-level investing at two of the world's largest platforms, across value, growth, and cyclical mandates. That experience has been codified into a disciplined, repeatable way of finding and underwriting exceptional businesses, applied here without the committee dilution of a large institution.

Why Now

Market concentration in mega-cap names leaves enormous opportunity in quality mid-caps. The post-rate-cycle regime rewards businesses with real earnings power. Emerging manager advantage: nimble sizing, no legacy positions, full conviction from day one.
