Updated from 10:19 a.m. ESTDiscount broker Charles Schwab ( SCHW) expects to earn 18 cents or 19 cents a share in the first quarter, CFO Chris Dodds said in an interview with TheStreet.com on Thursday. The guidance is above the current Thomson First Call consensus of 17 cents a share. In the first quarter of 2005, Schwab earned 11 cents a share. In the fourth quarter, the company earned 14 cents a share. Dodds' comments came after the company released its monthly volume update.

Average daily trades in February were 319,600, up 52% from a year earlier but down 4% from January. Meanwhile, Knight Capital ( NITE), one of the largest Nasdaq trading execution firms, said Monday that the dollar value of average daily trades rose 12.1% in February, compared with last year, to $8.92 billion. The number was down 10.5% from January. Average equity trade volume was down 6.7% from January to 977,000, an 11.4% increase from the same period last year. Average equity share volume was up 13.5% in February from the same period last year to 5.96 billion. Share volume increased 75.9% from January. "Market volumes fell off slightly from what was a very active January," said Thomas M. Joyce, chairman and CEO, Knight Capital Group. "In the shortest month of the year, indices slipped from what were four-and-a-half-year highs."
