🚀 Quick Start

pip install investormate

from investormate import Investor, Stock

# AI-powered analysis
investor = Investor(openai_api_key="sk-...")
result = investor.ask("AAPL", "Is Apple undervalued compared to its peers?")
print(result)

# Stock data and analysis
stock = Stock("AAPL")
print(f"Price: ${stock.price}")
print(f"P/E Ratio: {stock.ratios.pe}")
print(f"ROIC: {stock.ratios.roic}")  # Advanced ratios
print(f"TTM EPS: {stock.ratios.ttm_eps}")  # Trailing metrics
print(f"RSI: {stock.indicators.rsi()}")

# Batch load tickers (skips bad symbols with a warning)
stocks = Stock.batch(["AAPL", "MSFT", "GOOGL"], skip_invalid=True)

# Beneish detail (8 indices when statements allow)
detail = stock.scores.beneish_m_score_detail()
print(detail.get("indices"), detail.get("score"))
