"Understanding why an alpha works is far more valuable than finding one that works by accident."
Chia-Chun Chung comes from Hsinchu, the Taiwanese city at the heart of the island's semiconductor industry. He is a Senior AI Researcher in the automotive sector, a part-time PhD student in Computer Science at National Taiwan University, and a Computer Science graduate of National Yang Ming Chiao Tung University (NYCU). In 2025 he took bronze at the WorldQuant International Quant Championship, standing on the podium at Marina Bay in Singapore as one of twelve global finalists drawn from the top 0.02% of nearly 80,000 contestants who submitted some 263,000 alphas. He placed second in Stage 1 and first in Stage 2 on the way there.
His route into quant was unusual. An AI and reinforcement-learning researcher by day, he grew curious about how machine learning could be applied to markets, discovered WorldQuant's BRAIN platform through friends in quantitative finance, and found alpha-building "surprisingly addictive," treating each alpha as a small research project built on a hypothesis and refined with data. He manages his own portfolio through quantamental research, combining fundamental analysis with quantitative methods, trades with proprietary firms, and is now a WorldQuant Consultant.
Beyond the leaderboard, his deepest passion remains artificial intelligence: reinforcement learning, large language models, and building AI systems that help researchers generate new hypotheses and accelerate discovery. He has a knack for finding signal in unexpected places, once turning an observation about how traffic congestion builds and clears into hypotheses about how information propagates through markets and supply chains in waves. Away from the screen, music and reading are where many of his best ideas arrive.
Interview
How did you first discover WorldQuant and the BRAIN platform? Who or what led you there?
I first heard about WorldQuant through friends who were interested in quantitative finance. At that time, I was mainly working on AI research and reinforcement learning, but I became curious about how machine learning and data-driven research could be applied to financial markets. That curiosity led me to explore the BRAIN platform, and once I started building alphas, I found it surprisingly addictive. Every alpha is like a small research project: you form a hypothesis, test it with data, and continuously improve it.
NYCU was formed by merging two universities in 2021, a unique environment. How important was networking in your journey, and did the people around you influence your success at IQC?
Networking played a huge role in my journey. One of NYCU's greatest strengths is its diverse community. I had the chance to meet people from different backgrounds, including AI, computer science, finance, medical, and electrical engineering, and everyone brought a unique perspective to solving problems. For IQC, discussing ideas with friends was incredibly valuable. Many of my best ideas and improvements came from conversations rather than working alone. Sometimes a simple discussion can completely change how you think about an alpha. Having people who challenge your assumptions is one of the fastest ways to learn and grow.
When you wrote your very first alpha on BRAIN, what was it, what did it look like, and did it actually work?
My first alpha was actually very simple. I experimented with basic price and volume factors, trying to understand how the platform worked instead of chasing performance. It definitely wasn't a great alpha, and I don't even think it passed all the submission criteria. But it taught me the most important lesson: understanding why an alpha works is much more valuable than finding one that works by accident. Instead of giving up on that idea, I kept refining it. I expanded the original hypothesis, experimented with different variations, and gradually improved its performance until it became a much more robust alpha. That experience also taught me that building a good alpha is usually an iterative process rather than a one-time success.
