Fed Chairwoman Janet Yellen： asset valuations are “somewhat rich.”
Fed Vice Chairman Stanley Fischer: price-to-earnings ratios now stand in the top quintiles of their historical distributions.
San Francisco Fed President John Williams: the stock market is running on “fumes.”
但是，他（她）們接著又說：
Yellen and Fischer： capital built up at the nation’s biggest banks ... is now at multidecade highs.
Yellen says another crisis won't happen ‘this lifetime’.
John Williams: "It's something that clearly is a risk to the U.S. economy, some correction there -- it's something we have to be prepared for to respond to if it does happen."
聽出來話裏有話了嗎？俺來翻譯一下：目前股市太熱了，需要冷卻下來。但是如果調整過度（some correction），美聯儲就會有所反應（be prepared to respond it），絕不會讓它成為危機（another crisis won't happen ‘this lifetime’）。
如果市場按照FED的意思走的話，短期略熊或豬，要是跌過了會被及時拉起來的。
