FAQ

How is the Semiconductor sector index built?

It is TWSE's "半導體類指數", tracking the overall share-price movement of listed companies in the industry as a price index, without dividend reinvestment. 207 listed and OTC common stocks belong to this industry classification.

What is industry monthly revenue growth?

For companies in the industry that reported the month and had revenue in the same month last year, this month's combined revenue divided by last year's combined revenue minus 1. It shows the industry's operating momentum; companies report at different times, so early in the month fewer companies are included, and the number is shown.

How do I read the P/E position?

We take the median P/E of companies in the industry (positive values only) and compare it with the industry's median at each period over the last 5 years, showing the share of history that is at or below today. It is a relative position versus its own history, not a statement of cheap or expensive and not advice.
