Finance minister P Chidambaram announced that there was no cause for "worry or concern" after the Sensex crossed the 8,000 mark today, and asked investors to take informed decisions."The Sensex rise is not a cause for worry or concern. Stock market movement is orderly," Chidambaram said asserting that the government and Sebi were carefully looking at price to earnings (P/E) ratio of Nifty and Sensex."I expected Q2 results of business houses and banks to be as good as Q1 results," he added.
