Usage

Factor Research

from quant_research import FactorResearch

research = FactorResearch()

# Add factors
research.add_factor('momentum_20d', compute_momentum_20d)
research.add_factor('volatility_60d', compute_volatility_60d)
research.add_factor('roe', compute_roe)

# Analyze factor performance
ic_analysis = research.analyze_ic(
    factors=['momentum_20d', 'volatility_60d'],
    lookback=252
)

print(f"IC: {ic_analysis['ic_mean']:.3f}")
print(f"IR: {ic_analysis['ir']:.3f}")

Backtest

from quant_research import BacktestEngine

bt = BacktestEngine(
    start_date='2020-01-01',
    end_date='2024-12-31',
    initial_capital=1000000
)

# Add strategy
bt.add_strategy(MomentumStrategy(n=20, holding_period=60))

# Run backtest
results = bt.run()

print(f"Annual Return: {results['annual_return']:.2%}")
print(f"Sharpe Ratio: {results['sharpe_ratio']:.2f}")
print(f"Max Drawdown: {results['max_drawdown']:.2%}")

Portfolio Optimization

from quant_research import PortfolioOptimizer

opt = PortfolioOptimizer(returns_df)

# Mean-variance optimization
weights = opt.mean_variance(target_return=0.15)

# Risk parity
weights = opt.risk_parity()

# Black-Litterman
weights = opt.black_litterman(market_cap_weights, views)
