Shiller PE for Stocks: The True Measure of Stock Valuation


PT Telkom Indonesia (Persero) Tbk  (NYSE:TLK) 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.
