You should know "what is P/E ratio" and what this term means in your share trading life. Its very important for log term investers.
The P/E ratio (price-to-earnings ratio) of a stock (also called its "P/E", or simply "multiple") is a measure of the price paid for a share relative to the annual net income or profit earned by the firm per share.P/E reflects the capital structure of the company in question. P/E is a financial ratio used for valuation: a higher P/E ratio means that investors are paying more for each unit of net income, so the stock is more expensive compared to one with lower P/E ratio. In other words, P/E ratio shows current investor demand for a company share.
P/E ratio = Price per share / Annual Eaning per share
"Trailing P/E" or "P/E ttm": Earnings per share is the net income of the company for the most recent 12 month period, divided by number of shares outstanding. This is the most common meaning of "P/E" if no other qualifier is specified.
"Forward P/E", "P/Ef", or "estimated P/E": Instead of net income, uses estimated net earnings over next 12 months. Estimates are typically derived as the mean of a select group of analysts (note, selection criteria is rarely cited). In times of rapid economic dislocation, such estimates become less relevant as "the situation changes" (e.g. new economic data is published and/or the basis of their forecasts become obsolete) more quickly than analysts adjust their forecasts.
Companies with losses (negative earnings) or no profit have an undefined P/E ratio (usually shown as Not applicable or "N/A"); sometimes, however, a negative P/E ratio may be shown.
By comparing price and earnings per share for a company, one can analyze the market's stock valuation of a company and its shares relative to the income the company is actually generating. Stocks with higher (and/or more certain) forecast earnings growth will usually have a higher P/E, and those expected to have lower (and/or riskier) earnings growth will in most cases have a lower P/E. Investors can use the P/E ratio to compare the value of stocks: if one stock has a P/E twice that of another stock, all things being equal (especially the earnings growth rate), it is a less attractive investment.
By dividing the price of one share in a company by the profits earned by the company per share, you arrive at the P/E ratio. If earnings per share move proportionally with share prices the ratio stays the same. But if stock prices gain in value and earnings remain the same or go down, the P/E rises.
The earnings figure used is the most recently available, although this figure may be out of date and may not necessarily reflect the current position of the company. This is often referred to as a 'trailing P/E', because it involves taking earnings from the last four quarters.
The P/E ratio of a company is a significant focus for management in many companies and industries. This is because management is primarily paid with their company's stock (a form of payment that is supposed to align the interests of management with the interests of other stock holders), in order to increase the stock price. The stock price can increase in one of two ways: either through improved earnings or through an improved multiple that the market assigns to those earnings.
Its a good practise to watch the P/E ratio of the company before buying the stocks .
