传统上 a P/C Ratio of .80 or greater is considered bearish. Readings above 1.00 over a number of trading days are considered strong signs of a market bottom. Below 1.0, the readings are considered neutral in the .40-.50 range, and extremely bullish at readings below .30. The lower readings are considered strong signs of a topping market nearing a reversal.
这个我多次提到过。VIX,CPC,PUT/CALLRATIO 等情绪指标以PANIC INDEX 著名,主要是CONTRARIANS 用来抓底用的。当进入牛市,这些指标在低位运行时,它们对市场的方向不敏感,不能用来做看顶的主要指标。在牛市中,这些指标往上突破一点,大盘可能回调一点,也可能横盘调整,甚至在一些强势上涨时期,以较缓的上升曲线完成调整。换句话说,在牛市中,这些指标自身往上走走,大盘可能一点都不跌就完成调整了。看顶比看底的有效工具少得多,也难得多。看顶主要要看图形(LH,LL)和均线。
