# Stock Market Analysis

Use this skill when the user asks about equities, ETFs, mutual funds, indices, exchange quotes, market capitalization, price performance, ratings, price targets, analyst grades, sector P/E ratios, industry P/E ratios, sector snapshots, or industry performance.

## Workflow

1. Use `octagon_stock_data_research` for stock, ETF, mutual fund, index, or exchange questions. Do not call raw market-data APIs or scrape pages before using the Octagon tool.
2. Include precise symbols when available, such as `AAPL`, `MSFT`, `SPY`, `QQQ`, `VTSAX`, `FXAIX`, `^GSPC`, or `NASDAQ`.
3. Include exact date ranges for historical performance, index charts, market-cap history, sector snapshots, or industry snapshots.
4. Put the requested data fields in `metrics`, for example `quote`, `market cap`, `price performance`, `price targets`, `ratings snapshot`, `stock grades`, `sector P/E`, `industry P/E`, `ETF quote`, or `exchange quote`.
5. Use `outputFormat: "brief"` for quick quote lookups and `outputFormat: "research_note"` for comparisons, valuation context, or market commentary.
6. State the symbols, date range, and metrics used in the final answer. If a field is unavailable, say so plainly.

## Output Pattern

Prefer concise answers with:

1. Current snapshot or requested historical window.
2. Key metrics and comparisons.
3. Context from benchmarks, ratings, price targets, or sector/industry data when relevant.
4. Caveats about data availability, date ranges, and whether the answer is current or historical.
