A private practice, made public.

Exponential Quality is the public-facing arm of a private investment practice based in Singapore. The portfolio is a multi-generational family mandate, structured loosely on the Buffett Partnership model, with no external redemption pressure and a horizon measured in decades rather than quarters.

The work here is straightforward: I publish my analysis on the businesses I study, the decisions I make, and the framework I use to make them. The goal is not to give advice. The goal is to think clearly in public, and to find readers who want to do the same.

The framework

The investment philosophy is Charlie Munger's School of Value Investing which is called Buying Wonderful Companies at Fair Prices — WCAFP for short. Roughly 88% of the family's portfolio sits inside this framework. The remainder is allocated to deep value situations where the margin of safety comes from the price rather than the business.

WCAFP is sometimes confused with Growth-At-A-Reasonable-Price / GARP Investing. The distinction matters. Two principles separate them:

Research Analyst Background

My name is Shawn and my background is versatile, having completed studies in Systems Engineering at the diploma level, Sociology at the undergraduate level and Finance & Business Analytics at the post-graduate level. This variety of viewpoints and differing frameworks allows me to develop robust mental models (as was pioneered by the late Billionaire Investor Charlie Munger) used in investing, and as stated in the book Investing: The Last Liberal Art by Robert G. Hagstrom. I have read hundreds of investing, finance, economics and business books, and know what often works in investing and what doesn't work well. Join me on my investing journey as we all seek to have more than enough liquid assets for emergencies and a comfortable long-term retirement.

The track record

Over the five years from 27 May 2021 to 27 May 2026, the US equity sleeve has compounded at 34.04% CAGR against CSPX's 13.31%, generating approximately 2,073 basis points of annualised alpha. The overall family portfolio, which includes other geographies and asset categories, has compounded at 20.54% CAGR against VT's 10.71%, generating approximately 983 basis points of annualised alpha.

Returns are money-weighted nominal CAGR (IRR), calculated by Sharesight Portfolio Tracker from custodian-linked transaction records over the identical five-year window for both portfolios and benchmarks, and reflect the current holdings of each portfolio as at 27 May 2026. The MWR vs TWR distinction matters and is disclosed in detail on the homepage; in short, MWR reflects what the family's actual wealth compounded at, including the timing of capital additions, rather than the institutional-standard TWR which isolates investment-decision quality from cash-flow timing.

Five years is too short a window to claim skill. Fama-French and Andrew Lo are both explicit about this. What it does establish is a process — and a process is the only thing a long-horizon investor can actually own.

Performance attribution remains an open project. The next iteration of this practice involves formal factor decomposition to separate style exposure from genuine alpha. That work is in progress and will be published when complete.

The structural advantage

The single most important feature of this practice is not the framework or the track record. It is the mandate. A multi-generational family pool with no redemption pressure and a 30-year horizon does not need to outperform every quarter, or every year, or even every five years. It needs to compound — patiently, with conviction, through whatever the world throws at it.

That structural advantage is what allowed counter-cyclical capital deployment during the April 2025 drawdown, and it is what allows the patience required to hold genuinely wonderful businesses through their inevitable bad years.

What this site is — and isn't

This site is a place to read, learn, and think alongside a working practitioner. It is not a substitute for personalised financial advice, and nothing published here should be construed as such. I am not a licensed financial adviser. The writing is general commentary on publicly listed securities, intended for educated retail investors who want to develop their own conviction.

If you find the writing useful, the Sunday Letter is free. If you want to go deeper, The Quality Library teaches the framework in detail. If you want to follow the live portfolio work, Premium Research is the membership tier.

Either way — welcome. Read patiently. Think slowly. Own quality.
