Domestic stock markets started the week on a positive note tracking strength in Asian peers. The Sensex gained as much as 162.03 points to 36,033.51 in early trade, while the Nifty moved up 38.45 points to touch 10,830.10. The BSE benchmark index crossed the 36,000 mark in intraday trade for the first time since February 15. Gains in financial, auto and IT stocks pushed the markets higher, however losses in energy shares limited the upside. Analysts awaited key macroeconomic data due later this week.
