The price of the stock goes up or down depending on how well the company is doing and what people think about its future. P/E ratio is a way to compare how much money the company makes for each dollar you pay for the stock. If the P/E ratio is low, it means the stock might be cheaper and people think the company will do better in the future. If the P/E ratio is high, it means the stock might be more expensive and people are not so sure about the company's future. Read from source...

- The title is misleading as it does not specify what kind of overview the reader will get. Is it a price-to-earnings ratio overview or a general market overview? A more accurate and informative title would be "Price-to-Earnings Ratio Overview: CRH Inc."
- The article starts with irrelevant information about the stock's performance in the current session, past month, and past year. This does not help the reader understand the P/E ratio or its significance. A better introduction would explain what the P/E ratio is and how it is calculated.
