CHS, Acadia insiders latest to bank stock gains

The pace of stock sales among local insiders shows little sign of slowing down soon. David Miller, who was named Community Health Systems' first COO earlier this year, this week exercised 100,000 stock options that would have expired next July and then sold 100,000 shares at market prices. His gains on the deal — which was consummated shortly after Miller's CEO, Wayne Smith, made a similar move — topped $1.2 million.

At Acadia Healthcare, board member William Grieco has lately been trimming his stake in the Franklin-based behavioral health care company. Last week, he sold 7,000 shares for more than $350,000. This week, he unloaded roughly 4,500 more, banking almost $230,000.
