E10 is a concept invented by Prof. Robert Shiller, who uses E10 for his Shiller P/E calculation. E10 is the average of the inflation adjusted earnings of a company over the past 10 years.

Quality Systems Inc's adjusted earnings per share data for the three months ended in Dec. 2014 was $0.110. Since most companies do not have as long as 10 years history, here we use 6 years to calculate. Add all the adjusted EPS for the past 6 years together and divide 6 will get our E10, which is $0.81 for the trailing six years ended in Dec. 2014.


Definition

For the Shiller P/E, the earnings of the past 10 years are inflation-adjusted and averaged. The result is used for P/E calculation. Since it looks at the average over the last 10 years, the Shiller P/E is also called PE10.

The Shiller P/E was first used by professor Robert Shiller to measure the valuation of the overall market. The same calculation is applied here to individual companies.

Quality Systems Inc's Shiller P/E Ratio for today is calculated as

Shiller P/E Ratio=Share Price/E10
=16.29/0.81

Quality Systems Inc's E10 for the fiscal year that ended in Mar14 is calculated as:

For example, Quality Systems Inc's adjusted earnings per share data for the three months ended in Dec. 2014 was:

Adj_EPS=Earnigns per Share/CPI of Dec. 2014*CPI of Current
=0.11/235.51*235.189
=0.110

Since most companies do not have as long as 10 years history, GuruFocus uses 6 years to do the calculation.

Current CPI = 235.189.

Explanation

Compared with the regular P/E ratio, which works poorly for cyclical businesses, the Shiller P/E 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 P/E should give similar results to regular P/E.

Compared with the P/S ratio, the Shiller P/E makes the comparison between different industries more meaningful.


Be Aware

The Shiller P/E 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, the Shiller P/E and P/S ratio will give false valuations.
