E10 is a concept invented by Prof. Robert Shiller, who uses E10 for his Shiller PE Ratio calculation. E10 is the average of the inflation adjusted earnings of a company over the past 10 years.
Semiconductor Manufacturing International's adjusted earnings per share data for the three months ended in Mar. 2026 was ¥0.138. Add all the adjusted EPS for the past 10 years together and divide 10 will get our E10, which is ¥1.52 for the trailing ten years ended in Mar. 2026.
Shiller PE for Stocks: The True Measure of Stock Valuation
Semiconductor Manufacturing International (SHSE:688981) Shiller PE Ratio Explanation
Compared with the regular PE Ratio, which works poorly for cyclical businesses, the Shiller PE Ratio smoothed out the fluctuations of profit margins during business cycles. Therefore it is more accurate in reflecting the valuation of the company.
If a company has consistent business performance, the Shiller PE Ratio should give similar results to regular PE Ratio.
Compared with the PS Ratio, the Shiller PE Ratio makes the comparison between different industries more meaningful.
Be Aware
Shiller PE Ratio assumes that over the long term, businesses and profitability revert to their means. If a company's business model does not work in the future compared with the past, Shiller PE Ratio and PS Ratio will give false valuations.
