NEW YORK -- A discouraging profit forecast from Union Carbide weighed down the Dow Jones industrial average, but most stock indexes rose today as interest rates fell for the sixth straight session in the bond market. Dow loses 5.45
The Dow fell 5.45 points to close at 7,917.27 after trimming a 37-point deficit near the close. If not for a big drop by Union Carbide Corp., the Dow would have recorded a small gain. For the week, the Dow gained 174.30 points.
