Bernstein BUY signal

Extreme negative sentiment could provide a short term tactical trading opportunity according to Sanford Bernstein strategy team. "Our Composite Sentiment Indicator (CSI) has just triggered a buy signal. Over the past 22 years buy signals have been followed by positive 4 week forward global equity market returns over 70% of the time. We consider this signal as a potential short term tactical buying opportunity but remain cautious on equities over a medium term horizon"
