Hon Sing Sam Chung – Institutional Finance & Quantitative Investment Systems

This repository presents a set of finance-focused modelling frameworks spanning quantitative asset management, macro-financial risk, and corporate valuation, designed to reflect institutional investment workflows.

The projects are structured to demonstrate how alpha signals, portfolio construction, and risk frameworks interact within real-world investment systems.


Focus Areas

  • Quantitative asset pricing and systematic trading strategies
  • Multi-asset portfolio construction and risk management
  • Macroeconomic and balance-sheet stress testing
  • Private equity and leveraged buyout modelling
  • M&A valuation and transaction analysis

Flagship Projects

Volatility-Conditioned Momentum Engine (Multi-Asset)

A multi-asset systematic trading framework that conditions time-series momentum exposure on volatility regimes, extending a regime-dependent asset pricing insight into a fully implemented trading system.

Used to analyse:

  • Regime-dependent behaviour of momentum (continuation vs reversal)
  • Cross-asset signal robustness (equities, bonds, commodities, FX)
  • Transaction cost sensitivity (0, 2, 10 bps) and turnover dynamics
  • Crisis-period performance (GFC, COVID, 2022 inflation bear)
  • Statistical significance (HAC inference) and factor exposure (CAPM)

→ Repository: volatility-conditioned-momentum-engine


Macro-Financial Stress Testing

Scenario-based macro-financial stress testing framework for evaluating the impact of adverse macroeconomic conditions on bank balance sheets, credit losses, and capital adequacy.

Used to analyse:

  • Conditional capital depletion under adverse macro scenarios
  • Timing and magnitude of CET1 shortfalls
  • System-level vulnerability to macro-financial shocks

→ Repository: macro-financial-stress-testing


M&A Valuation Engine

Comprehensive corporate valuation framework for analysing acquisition targets and evaluating transaction economics across multiple valuation methodologies.

Used to analyse:

  • Standalone enterprise value using trading comparables and precedent transactions
  • Intrinsic firm value via multi-scenario discounted cash flow modelling
  • Deal economics including control premiums, consideration structure, and accretion/dilution outcomes
  • Sensitivity of valuation to key assumptions such as WACC, terminal value, and strategic synergies

→ Repository: mna-valuation-engine

System Architecture (Conceptual)

The projects collectively reflect a layered investment framework:

  • Signal Layer
    Systematic strategies (e.g. volatility-conditioned momentum) generating directional views

  • Portfolio Layer
    Multi-asset allocation, weighting schemes, and diversification

  • Risk & Execution Layer
    Transaction costs, drawdown control, and capital allocation constraints

This structure mirrors how institutional investment systems are designed in practice.


How to Use

Each repository contains:

  • A detailed README explaining financial intuition
  • Clear assumptions and limitations
  • Reproducible outputs (CSV and visual diagnostics)
  • Modular components suitable for extension
