# Yahoo Finance CLI

Financial data terminal powered by Yahoo Finance. All commands via the `yf` script.

## Setup

The script is at `{baseDir}/scripts/yf`. It uses `uv run --script` with inline PEP 723 metadata — dependencies install automatically on first run.

```bash
chmod +x {baseDir}/scripts/yf
```

## Commands

| Command | Purpose | Example |
|---------|---------|---------|
| `yf price TICKER` | Quick price + change + volume | `yf price YPF` |
| `yf quote TICKER` | Detailed quote (52w, PE, yield) | `yf quote AAPL` |
| `yf compare T1,T2,T3` | Side-by-side comparison table | `yf compare YPF,PAM,GGAL` |
| `yf credit TICKER` | Credit analysis: leverage, coverage, debt maturity | `yf credit YPF` |
| `yf macro` | Morning macro dashboard (UST, DXY, VIX, oil, gold, BTC, ARS) | `yf macro` |
| `yf fx [BASE]` | LatAm FX rates (ARS, BRL, CLP, MXN, COP) | `yf fx USD` |
| `yf flows ETF` | ETF top holdings + fund data | `yf flows EMB` |
| `yf history TICKER [PERIOD]` | Price history (1d/5d/1mo/3mo/6mo/1y/ytd/max) | `yf history YPF 3mo` |
| `yf fundamentals TICKER` | Full financials (IS, BS, CF) | `yf fundamentals YPF` |
| `yf news TICKER` | Recent news headlines | `yf news YPF` |
| `yf search QUERY` | Find tickers | `yf search "argentina bond"` |

All commands support `--json` for machine-readable output.

## When to Use Which Command

- **Morning check**: `yf macro` → get UST yields, DXY, VIX, commodities, BTC, ARS in one shot
- **Quick look**: `yf price TICKER` → fast price/change/volume
- **Deep dive equity**: `yf quote` → `yf fundamentals` → `yf history`
- **Credit analysis**: `yf credit TICKER` → leverage ratios, interest coverage, debt breakdown
- **EM/LatAm FX**: `yf fx` → all major LatAm pairs vs USD
- **ETF research**: `yf flows ETF` → top holdings, AUM, expense ratio
- **Comparison**: `yf compare` → side-by-side for relative value

## Error Handling

The script handles bad tickers, missing data, and rate limits gracefully with clear error messages. If Yahoo Finance rate-limits, wait a moment and retry.

## Output

By default, output uses Rich tables for clean terminal display. Add `--json` to any command for structured JSON output suitable for piping or further processing.
