目前的巴菲特指数和Shiller PE

目前标普市值接近GDP的200% （参考 无脑定投指数ETF也该留意巴菲特指数 ）

Shiller PE 的警戒线是 30， 现在是35。当然1997年达到这个警戒线， 仍然涨到2000年44股市才崩溃。

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.
