Healthways hits 21-month high

Shares of Healthways (Ticker: HWAY) are up more than 3 percent to about $13.70 in Tuesday afternoon trading, a sign that investors are buying into the company's promise that the second half will deliver some serious profit growth. That has taken them to their highest level since Aug. 1, 2011.

On a completely unrelated note, Healthways officials this morning put out a press release pointing to a study published in the Journal of Occupational and Environmental Medicine that provided new — and quantifiable — links between people's well-being and their workplace productivity. A quarter of the more than 19,000 people in that study were able to lower their physical health risks and improve their productivity. The average gain to their employer: $468 per year.
