PE refers to the price-earnings ratio of stocks, also called "profit rate". The cost-benefit ratio is the ratio of the common stock price to the earnings per share of a certain stock. So it is also called stock price-earnings ratio or market price-earnings ratio (P/E ratio).

( 1)

Price-earnings ratio PE includes static price-earnings ratio PE and dynamic price-earnings ratio PE.

: static PE= share price/earnings per share (EPS) (year) dynamic PE= share price * total share capital/net profit for the next year (you need to make your own prediction)

The P/E ratio relates the stock price to the profit, which reflects the recent performance of the enterprise. If the stock price rises, but the profit remains the same, or even falls, the P/E ratio will rise.

(2)PE is a job, and English is product engineering, but it is also translated into project engineering.

Product engineering product engineering, a technician, called PE technician; If you are an engineer, call it a PE engineer. This position in the factory is mainly to solve problems in the production process and do work instructions. Belong to a lower position.

Project engineering, project engineering. Is designed for a product, overall planning and project management. Usually at the top of the company.

(3)PE is the abbreviation of private equity fund, commonly known as private equity investment fund. Different from private equity investment funds, PE mainly refers to investment funds that raise funds and invest in shares of unlisted companies, and a few PEs invest in shares of listed companies.

(4)PE, the full name of polyethylene, is the simplest polymer organic compound and the most widely used polymer material in the world today. It is polymerized from ethylene and can be divided into high density polyethylene, medium density polyethylene and low density polyethylene according to different densities. Low density polyethylene (LDPE) is soft and usually polymerizes under high pressure. High density polyethylene (HDPE) has the characteristics of high rigidity, hardness and mechanical strength, and is usually polymerized at low pressure. High-density polyethylene can be used as containers, pipes and high-frequency electrical insulation materials for radar and television. Low density (high pressure) polyethylene is often used in large quantities. Polyethylene is waxy and has waxy smoothness. When undyed, low-density polyethylene is transparent, while high-density polyethylene is opaque.
