Corporate News Not the Key Nishtar THE stock market made no further retreat last week. Instead, it put up a steadier appearance and staged a small recovery. The price pattern over the weekend was a mixed one, but plus signs far outnumbered the minus signs for the first time in many weeks. Institutional support for select counters, scarcity of fresh offerings, and some replacement buying and bargain hunting, contributed in varying measure to last week's steadier tone. Turnover, though somewhat better, was still on the very low side.
