• the financial ratio, one of the most important indicators for valuing a company and determining a stock's relative valuation;
• trailing P/E ratio is the most popular P/E metric, as it's the most objective, of course in case of the company reported its earnings results fairly;

There are several types of P/E Ratios:

• Trailing (based on the backward-looking basis) Twelve Month PE Ratio or P/E Ratio (TTM): is calculated using the earnings per share over the past 12 months.
• Forward P/E Ratio (based on the projected basis): is calculated using the expected (upcoming, forecasted) earnings for the next twelve months.
• P/E Ratio without NRI (without Non-Recurring Items): the reported earnings less the non-recurring items are used.
• Shiller P/E Ratio: the earnings of the past 10 years are inflation-adjusted and averaged.

The main types of P/E ratio are trailing and forward.

RESULT INTERPRETATION:

• P/E Ratio can be applied to the stocks across different industries.
• The lower the P/E ratio, the better. The low P/E ratio can indicate that a company may currently be undervalued. However, it is quite crucial to understand the reasons behind a company’s low P/E ratio. Sometimes, the it may indicate that the company's business model is in decline, and investors expect its earnings to decline.
• Lower P/E ratio may indicate the company has solidified its market share.
• Stocks with low P/E ratios: Value stocks; stocks with low growth potential.
• Mature industries that pay a steady rate of dividends have a low P/E ratio.
• The high P/E ratio could indicate that a company's stock is overvalued (i.e., securities that trade higher than their fair market value), but, from the other hand it may just reflect a trend within the sector.
• Higher P/E ratio might mean investors expect higher earnings growth in the future. High growth stocks, growth tech stocks often have a high P/E ratio.
• The high P/E ratio often indicates increased demand.
• According to Peter Lynch, a company with P/E Ratio equal to its growth rate is fairly valued.
• Stocks with the same P/E Ratio - the one with faster growth business is more attractive.
• Negative P/E means that a company is not profitable, it shows how much money the company lost with every dollar (euro) of invested funds.
• P/E ratio calculation is meaningless if the company loses money and has no earnings.
• If P/E ratio is expressed as N/A (not applicable or not available), thus, it means a company has zero or negative earnings per share (EPS), and, thus, it has no earnings or is posting losses. Note, that the company can also have a P/E ratio of N/A if it is newly listed on the stock exchange and has not yet reported earnings.
• The company's P/E ratio should only be used as a comparative tool when considering companies in the same sector (same industry); or when comparing a company against its own historical P/E data.
• Note: earnings can be manipulated, and, it means, P/E ratio should never be relied on as a sole indicator in investment decision-making process.
• PE Ratio without NRI is a more accurate indication of valuation than PE Ratio.
