目前標普市值接近GDP的200%。 再買無妨,得有能力全身而退。
Shiller PE 的警戒線是 30, 現在是35。當然1997年達到這個警戒線, 仍然漲到2000年44股市才崩潰。
The Shiller P/E gives investors a read on whether the stock market—as represented by the S&P 500—is overvalued or undervalued. The higher the Shiller P/E ratio, the more overvalued a market.
For context, over more than 100 years, the average and median Shiller P/E ratio has been around 15 or 16, spiking up significantly higher often before market crashes.
