KARACHI - The stock market lost 159 points on Wednesday amid selling pressure, which was triggered by the worsening law and order situation.

Moving here and there, going nowhere is the only way I can describe the market, said Shahid Ali, CEO HMFS adding, it is more of a consolidation phase rather a bearish or bullish sentiment dominating the market sentiment. Market rumours suggest that market can move backwards to 4,500 mark, but the question arises whether the fundamentals justify such market move or not. Most of the companies have already announced their results along with lot of companies beating analyst expectations. In such a scenario current phase can or may be termed as a temporary consolidation phase, he added.
