Japan Price to Earnings (ttm)
The P/E ratio is arguably the most common method for determining valuations of both individual stocks and the market as a whole. The P/E ratio divides the price by the earnings of the trailing twelve months. This can be problematic when earnings are temporarily depressed during a recession and the ratio becomes useless. This can be largely avoided by using other forms of the P/E such as the cyclically adjusted P/E, or by using other metrics altogether such as the price to book ratio.
