Dow Jones & Co. reported that its profit edged up 2.1% in the second quarter and repeated an earlier prediction of "only modest earnings gains until fall." Warren H. Phillips, chairman and chief executive, said one reason for the small rise in earnings was that the second quarter of 1984 was so strong. He also said that the volume of classified advertising was down 4.2% in the Wall Street Journal during the second quarter. Circulation on June 30 was 3.8% below a year earlier.
