## About

### The problem

A stock's price says little by itself; whether it is cheap depends on its earnings, its book value and its growth.

### The approach

The analyzer assesses a stock with three ratios, P/E, P/B and PEG, compared against historical and industry benchmarks, with IDR formatting for the Indonesian exchange. It uses only the Python standard library.

- Choose one method (PER, PBV, PEG) or all of them.
- Input validation, confidence levels and a written reason for each verdict.
- An interactive mode, a programmatic API and examples.

### The result

A small, clear tool for a first valuation opinion. It informs, it does not advise.

## Features

- **Three Ratios**: P/E, P/B and PEG, each analysed separately.
- **Reasoned Verdicts**: Confidence levels and an explanation for every assessment.
- **No Dependencies**: Only the Python standard library.
