Stock price indexes are back at record highs. Yet the stock market's sentiment indicators have turned stubbornly bearish over the past couple of weeks.

Last week, the 10-year Treasury bond yield fell from 4.79% on January 14 to 4.60% today. That move was triggered by cooler-than-expected inflation news and dovish comments by a Fed governor.
