Sensex Today: Sensex and Nifty staged a blockbuster start to the week as both indices rallied sharply past key milestones today. Sensex surged past 73,000 for first time and Nifty above 22,000. Buying action in tech stocks again lifted the indices on Dalal Street today. Benchmark indices also outperformed broader markets."The rally in the market, primarily driven by momentum, is now getting support from fundamentals. The sharp bounce in large cap IT stocks on the back of slightly positive management commentary indicates that an underperforming segment can surprise on the upside on news of a turnaround in the sector. The IT index which shot up by 5% on Friday will remain firm since HCL Tech and Wipro have more room on the upside. Nifty has broken out on the upside from the consolidation range and shows signs of further up move. RIL, large cap IT and banking majors can provide fodder for the bulls in the near-term," said Dr. V K Vijayakumar, Chief Investment Strategist, Geojit Financial Services.Highlights of trade:Sensex, Nifty hit fresh record highs todayMedi Assist IPO opens for subscription
