Ahsan Mehanti at Arif Habib Investments said that the stocks turned bullish at KSE on high expectations for early resolution of capital gain tax issues at the local bourse and easing political concerns after return of President and meeting between Prime Minister and army chief. He said that the trade remained on higher side ahead of corporate earnings announcements as institutional investors accumulated oversold scrips on strong valuations. He said that the rising local commodity prices invited fresh buying in commodity stocks in oil and fertiliser sectors despite concerns for global economic uncertainty affecting foreign interest at KSE.
