What is GigaDevice Semiconductor E10?

GigaDevice Semiconductor SHSE:603986 +2.02% 83 E10 is ¥1.78 as of Mar. 2026. GuruFocus rates SHSE:603986 with a GF Score™ of 83/100 and a GF Value™ of ¥254.18 (Significantly Overvalued). The stock has 5 warning signs investors should review.

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.

GigaDevice Semiconductor's adjusted earnings per share data for the three months ended in Mar. 2026 was ¥2.180. Add all the adjusted EPS for the past 10 years together and divide 10 will get our e10, which is ¥1.78 for the trailing ten years ended in Mar. 2026.

During the past 12 months, GigaDevice Semiconductor's average E10 Growth Rate was 29.00% per year. Please click Growth Rate Calculation Example (GuruFocus) to see how GuruFocus calculates Wal-Mart Stores Inc (WMT)'s revenue growth rate. You can apply the same method to get the E10 growth rate using E10 data.

As of today (2026-08-01), GigaDevice Semiconductor's current stock price is ¥378.60. GigaDevice Semiconductor's E10 for the quarter that ended in Mar. 2026 was ¥1.78. GigaDevice Semiconductor's Shiller PE Ratio of today is 212.70.

During the past 13 years, the highest Shiller PE Ratio of GigaDevice Semiconductor was 432.58. The lowest was 45.59. And the median was 86.55.


GigaDevice Semiconductor  (SHSE:603986) E10 Explanation

If a company grows much fast than inflation, E10 may underestimate the company's earnings power. Shiller PE Ratio can seem to be too high even the actual P/E is low.

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.

GigaDevice Semiconductor's Shiller P/E Ratio of today is calculated as

Shiller PE Ratio=Share Price/E10
=378.60/1.78
=212.70

GigaDevice Semiconductor E10 Calculation

E10 is a concept invented by Prof. Robert Shiller, who uses E10 for his Shiller P/E calculation. When we calculate the today's Shiller P/E ratio of a stock, we use today's price divided by E10.

What is E10? How do we calculate E10?

E10 is the average of the inflation adjusted earnings of a company over the past 10 years. Let's use an example to explain.

If we want to calculate the E10 of Wal-Mart (WMT) for Dec. 31, 2010, we need to have the inflation data and the earnings from 2001 through 2010.

We adjusted the earnings of 2001 earnings data with the total inflation from 2001 through 2010 to the equivalent earnings in 2010. If the total inflation from 2001 to 2010 is 40%, and Wal-Mart earned $1 a share in 2001, then the 2001's equivalent earnings in 2010 is $1.4 a share. If Wal-Mart earns $1 again in 2002, and the total inflation from 2002 through 2010 is 35%, then the equivalent 2002 earnings in 2010 is $1.35. So on and so forth, you get the equivalent earnings of past 10 years. Then you add them together and divided the sum by 10 to get E10.

Please note that we use the CPI data of the country/region where the company is headquartered. If the CPI data for that country/region is not available, then we will use the CPI data of the United States as default.

For example, GigaDevice Semiconductor's adjusted earnings per share data for the three months ended in Mar. 2026 was:

Adj_EPS= Earnings per Share (Diluted) /CPI of Mar. 2026 (Change)*Current CPI (Mar. 2026)
=2.18/116.3033*116.3033
=2.180

Current CPI (Mar. 2026) = 116.3033.
