I'm Titus Zhang. I work across cross-sectional equity research, portfolio construction, risk analytics, and the research systems that make results reproducible.
01 / Selected work
Quantitative research · Python
A public research framework for ranking U.S. equities by forward 10-day returns, with expanding-window validation, purged boundaries, a final untouched OOS audit, and explicit portfolio costs and limitations.
Research tooling · Local-first
A macOS research workbench that unifies experiment setup, factor diagnostics, backtest review, artifact traceability, and bounded report generation while keeping data and credentials on the user's machine.
Financial data product · Full stack
A trustworthy financial-news inbox that groups related public headlines into stable stories, preserves source lineage, and separates relevance, importance, credibility, and freshness for research triage.
02 / Research practice
Split time before feature construction, purge overlapping labels, and make the signal, execution, and evaluation clocks explicit.
Track turnover, exposure, and transaction-cost sensitivity before interpreting portfolio returns or model rankings.
Separate research evidence from trading claims and keep data, execution, and comparison limits visible beside every result.
03 / Experience
Asymptote Capital · Remote program
Completed mentor-guided research on IC-data validation, overlapping-return inference, correlated multiple testing, and pre-specified out-of-sample signal-decay checks.
Oceanum · Shanghai
Built configurable SQL and Python data workflows and extended a credit-policy simulation across approval, profit, staffing, error, and bad-debt trade-offs.
Xinsheng Group · Shanghai
Built an A-share cross-sectional research dataset, benchmarked sequence models against simpler baselines, and evaluated a weekly portfolio with stability, exposure, turnover, and cost controls.
