Shares of Buckeye Technologies ( BKI) were among the NYSE's losers Monday, slumping 11% after the specialty-fibers maker warned that its fiscal third-quarter earnings would fall short of Wall Street's expectations. The company now expects earnings will be "near breakeven" for the quarter ending this month. Previously, the company projected it would earn slightly more than $1.9 million, or 5 cents a share. Analysts polled by Thomson First Call project earnings of 9 cents a share. During the year-ago period, the company earned $4.1 million, or 11 cents a share. "Manufacturing difficulties at our large wood-pulp mill in Florida related to the start-up of new equipment and transportation issues, which reduced revenue, have negatively impacted our business," Buckeye said.

CSK Auto ( CAO) fell 7% after the auto-parts retailer postponed the release of its fourth-quarter results because of accounting errors and irregularities that were found during an audit.

CSK said that it plans to file its financial statements as soon as "reasonably practicable." Shares were down $1.18 to $14.72.
