Pakistan Stock Exchange (PSX) witnessed a volatile session on Tuesday, with the benchmark KSE-100 Index shedding 74.06 points (-0.10 percent) to close at 71,359.40 points. The market opened on a sharp positive note; however, trading at the KSE-100 remained volatile throughout the session as the index swayed both ways. The index came under heavy selling pressure in the last 45-minute session amid profit taking activity; otherwise, the session remained range-bound. The benchmark index has surged 73.63 percent over the past year and is up 10.36 percent year-to-date. According to experts, Pakistan is aiming to agree on the outline for a new International Monetary Fund (IMF) loaan, which has been helping sustain the record-breaking spree. Moreover, good March quarter dividends are helping share prices which despite rallying are trading at a forward looking price-earnings ratio of 4, they added.
