Sino-American Silicon Products (LUX:SIAMS) PE Ratio (TTM) Explanation
The PE Ratio (TTM) can be viewed as the number of years it takes for the company to earn back the price you pay for the stock. For example, if a company earns $2 a share per year, and the stock is traded at $30, the PE Ratio (TTM) is 15. Therefore it takes 15 years for the company to earn back the $30 you paid for its stock, assuming the earnings stays constant over the next 15 years.
In real business, earnings never stay constant. If a company can grow its earnings, it takes fewer years for the company to earn back the price you pay for the stock. If a company's earnings decline it takes more years. As a shareholder, you want the company to earn back the price you pay as soon as possible. Therefore, lower P/E stocks are more attractive than higher P/E stocks so long as the PE Ratio (TTM) is positive. Also for stocks with the same PE Ratio (TTM), the one with faster growth business is more attractive.
If a company loses money, the PE Ratio (TTM) becomes meaningless.
To compare stocks with different growth rates, Peter Lynch invented a ratio called PEG Ratio. PEG Ratio is defined as the PE Ratio (TTM) divided by the growth ratio. He thinks a company with a PE Ratio (TTM) equal to its growth rate is fairly valued. Still he said he would rather buy a company growing 20% a year with a PE Ratio (TTM) of 20, instead of a company growing 10% a year with a PE Ratio (TTM) of 10.
Because the PE Ratio (TTM) measures how long it takes to earn back the price you pay, the PE Ratio (TTM) can be applied to the stocks across different industries. That is why it is the one of the most important and widely used indicators for the valuation of stocks.
Investors need to be aware that the PE Ratio (TTM) can be misleading a lot of times, especially when the underlying business is cyclical and unpredictable. As Peter Lynch pointed out, cyclical businesses have higher profit margins at the peaks of the business cycles. Their earnings are high and PE Ratio (TTM)s are artificially low. It is usually a bad idea to buy a cyclical business when the PE Ratio (TTM) is low. A better ratio to identify the time to buy a cyclical businesses is the PS Ratio .
PE Ratio (TTM) can also be affected by non-recurring-items such as the sale of part of businesses. This may increase for the current year or quarter dramatically. But it cannot be repeated over and over. Therefore PE Ratio without NRI is a more accurate indication of valuation than PE Ratio (TTM).

There are at least three kinds of PE Ratio (TTM)s used by different investors. They are Trailing Twelve Month PE Ratio (TTM) or PE Ratio (TTM) (TTM), Forward PE Ratio, or PE Ratio without NRI. A new PE Ratio (TTM) based on inflation-adjusted normalized PE Ratio (TTM) is called Shiller PE Ratio, after Yale professor Robert Shiller.
In the calculation of PE Ratio (TTM), the earnings per share used are the earnings per share over the past 12 months. For Forward PE Ratio, the earnings are the expected earnings for the next twelve months. In the case of PE Ratio without NRI, the reported earnings less the non-recurring items are used.
For Shiller PE Ratio, the earnings of the past 10 years are inflation-adjusted and averaged. Since it looks at the average over the last 10 years, Shiller PE Ratio is also called PE10.
