Add to this portfolio's Playbook:
Philosophy: Long-term value investing. Buy quality businesses trading below intrinsic value and hold for years.
Universe: US and Hong Kong listed companies. Profitable, established businesses.
What I look for: durable competitive advantages, consistent free cash flow, strong balance sheets, capable management, and a margin of safety between price and intrinsic value.
What I avoid: unprofitable companies, high leverage, businesses I can't understand, and hype-driven valuations.
Risk and sizing: maximum 10% per position, concentrated portfolio of high-conviction names, long holding periods.
Research style: prioritize business quality, moat durability, free cash flow, balance sheet strength, and valuation versus intrinsic value. Always state the bear case and what would break the thesis.
