The Sensex breached the 22,000 mark for the first time on Monday on the back of continued overseas investor interest linked to upcoming polls.
The NSE 50-shares Nifty also touched a new intra-day peak of 6,562.20 during the week surpassing previous lifetime peak of 6,537.80 hit on last Friday.
The buoyant mood was somehow disturbed by country's exports which contracted 3.67 per cent in February to USD 25.68 billion.
"Buoyed by better than expected macro-economic data, equity benchmarks were seen making a positive start. However, gains remained capped as some cautiousness crept in the market as SEBI has tightened norms to prevent money laundering through capital markets," said Jayant Manglik, President, Retail Distribution, Religare Securities.
Meanwhile, retail inflation eased to 25-month low of 8.1 per cent in February and industrial growth registered a modest growth of 0.1 per cent in January. WPI inflation also eased to nine-month low of 4.68 per cent in February.
