📅 Career Timeline
2009
Joined Seeking Alpha
Began publishing independent equity research. Built a reputation for contrarian biotech and small-cap calls — often going against consensus and being proven right by the data.
2015
Founded The Biotech Forum
Launched a premium research community on Seeking Alpha with a model portfolio, live discussion, and weekly deep-dive research. Maintained a 4.6★ rating across thousands of members.
2024
SA Quant Strategy Launch
Merged 15 years of fundamental research with systematic quantitative methods. Built a multi-factor model spanning value, momentum, quality, and volatility dimensions — applied to the small-cap universe with rigorous statistical validation.
2026
Global HNW Community
Expanded to serve high-net-worth investors across the United States, Israel, South Korea, and Taiwan — executing the SA Quant methodology with institutional-grade infrastructure.
🧬 Investment Philosophy
🔬
Data Over Narrative
Every investment thesis must survive quantitative scrutiny. We don't invest in stories — we invest in statistically validated factor signals. If the numbers don't back it, we don't buy it.
🛡️
Risk-First Design
Small caps carry asymmetric risk. Our four-layer screening system is designed to eliminate the bottom two-thirds of the universe before we even analyze fundamentals. Downside protection is engineered in, not bolted on.
🎯
Contrarian by Conviction
The best opportunities live where the crowd isn't looking. HK small caps with negative sentiment but improving fundamentals. Biotech names the market has written off. We go where the data leads — not where the headlines point.
🌍
Global Perspective
Alpha doesn't respect borders. Our strategies span Hong Kong, US, and emerging markets — applying the same rigorous factor framework across geographies. Diversification across markets, not just sectors.
What We're NOT
❌
Not a Black Box
Every factor, every screen, every signal is explained. We publish our methodology openly. If you can't explain why you own something, you shouldn't own it.
❌
Not High-Frequency
We rebalance quarterly, not millisecondly. Our edge comes from factor selection and cross-validation — not speed. This is systematic investing for real portfolios, not algorithmic gambling.
❌
Not for Everyone
Small-cap quant strategies require patience. Drawdowns happen. If you need monthly liquidity or can't stomach 12% temporary declines, this approach isn't for you. We're transparent about that.
👥 Our Team
