Hiring a quant researcher costs $300K/year. This one is free, open-source, and works 24/7.

Alpha Skills turns any AI coding assistant into a senior quantitative researcher. It discovers factors, evaluates them with institutional-grade methodology (IC/ICIR/quintile/robustness), monitors for alpha decay, and runs multi-factor backtests — all from a single sentence.

What Can It Do

You say one sentence. It does the rest.

You:  "Evaluate the price-volume divergence factor"
AI:   📊 IC Mean=0.066 | ICIR=0.696 | Rating: ⭐ Strong
      Quintile spread monotonic. Best holding period: 20 days.
      Report saved → output/eval_pv_diverge.png

You:  "Mine 50 candidate factors and show me the best ones"
AI:   ⛏️ Scanned 50 candidates → 12 passed IC screen
      Top: PV divergence 20d (ICIR=0.70), Low downside vol (ICIR=0.53)...
      Register to library?

You:  "Backtest using my top 3 factors"
AI:   📈 Sharpe=0.74 | MaxDD=-13.9% | Profit Factor=2.24
      Gate check: ✓ PF>1 ✓ MDD>-25% ✗ Sharpe<1.0

No boilerplate. No notebooks. No 200 lines of pandas. Just results.

Quick Start

1. Get the skills

git clone https://github.com/VernonOY/alpha-skills.git

2. Load into your AI assistant

| Platform | How | |----------|-----| | Cursor | Copy skills/alpha-*/SKILL.md → .cursorrules | | Windsurf | Copy → .windsurfrules | | Claude Code | cp -r skills/alpha-* ~/.claude/skills/ | | Any LLM | Paste SKILL.md as system prompt |

3. Install Python deps

pip install pandas numpy scipy matplotlib pyarrow
pip install tushare    # A-share
pip install yfinance   # US / HK

4. Talk to it

"evaluate the momentum_20 factor"
"mine volatility factors"
"backtest my top 3 factors, 2022 to 2025"

Multi-Market: A-Share · Hong Kong · US

Zero framework dependency. Each skill is a self-contained Markdown file. The AI reads it, writes the Python, runs it. Nothing to install except standard data science packages.

Evaluation Pipeline

Your AI quant researcher doesn't just compute IC. It runs a 4-level institutional-grade evaluation:

| Level | What | Speed | |-------|------|-------| | L0 | Syntax + data validation | instant | | L1 | Quick IC screen (sampled 200 stocks × 2 years) | <30s | | L2 | Full: IC series, ICIR, quintile returns, long-short, monotonicity | 1-3 min | | L3 | Robustness: parameter perturbation, rolling window, start-date sensitivity | 5-15 min |

Plus optional qtype pre-flight — static analysis to catch look-ahead bias before you waste compute on fake alpha.

Factor Mining Engine

alpha-mine systematically searches the factor expression space:

3 mining strategies:

Template-based — momentum, mean-reversion, volatility, volume, composite templates × multiple window sizes
Combinatorial — chain operators: cs_rank(ts_corr(close, volume, 20))
Mutation — take a known strong factor, mutate parameters/operators

Pipeline: Generate 50+ candidates → IC quick screen → full evaluate top 10 → LLM judges economic intuition → present ranked results

Overfitting guard: Every surviving factor gets an economic intuition score (Strong / Moderate / Weak). Factors without a clear behavioral story are flagged as potential data mining.

Built-in Factors (25+)

| Category | Factors | |----------|---------| | Price-Volume | momentum · reversal · volatility · pv_diverge · rsi · macd · bollinger · atr_ratio · turnover · abnormal_turnover | | Fundamental | roe · roa · gross_margin · net_profit_growth · revenue_growth | | Valuation | pe_ttm · pb · ps_ttm · dividend_yield · peg | | Composite | quality_score · value_score · growth_momentum |

All gate checks and evaluation thresholds are user-configurable:

GATE_SHARPE: 1.0
GATE_MAX_DRAWDOWN: -0.25
GATE_PROFIT_FACTOR: 1.0
EVAL_ICIR_STRONG: 0.5

Stop writing boilerplate. Start finding alpha. Built by quants who got tired of copy-pasting the same IC calculation for the 500th time.
