Stock analysis combines fundamental metrics (such as the price-to-earnings ratio and earnings per share) with technical indicators (such as the Relative Strength Index and trading volume) to help investors assess whether a stock is fairly valued, overvalued, or undervalued. No single metric can tell you the whole story about a stock.
The price-to-earnings ratio compares a company’s share price with its earnings per share, while the Relative Strength Index measures the speed and magnitude of recent price movements to identify potential overbought or oversold conditions.
Trading volume shows how actively a stock is being bought and sold, which can confirm or call into question the strength of a price movement.
