analyze-stock

Analyze individual stocks, ETFs and open-end funds for A-shares / Hong Kong stocks / US stocks. Call this when a user asks about a ticker's trend, buy/sell recommendation, entry/exit levels, whether it can be traded, position increase/decrease, fund holdings / manager / returns, liquidity / turnover / market impact cost, ETF premium/discount / tracking error / NAV. Supports single-symbol or mixed-batch queries. Also supports `--correlation` to compute rolling correlation, beta, downside beta, annualized volatility and maximum drawdown versus CSI 300 / CSI 500 / Shanghai Composite (for US stocks: SPY/QQQ). The CLI only fetches raw data; analysis and tactical recommendations are produced by the caller (Claude) based on those objective data. No LLM_API_KEY is required. Do not use this for overall market review (use market-review for that).
