Shares of Pemco Aviation(PAGI Quote) were among the Nasdaq's losers Monday after the company posted disappointing second-quarter earnings results.

The aircraft-maintenance company posted a second-quarter loss of 28 cents a share on sales of $43.5 million. A year ago, it earned 49 cents a share on sales of $47.3 million.
