The key domestic benchmarks are likely to open higher today as investors cheer the fastest growth in two and a half years in Asia’s third biggest economy last quarter. Indian economy expanded by 5.7 per cent in the April-June quarter of FY 2014-15 from the same period a year ago, the fastest pace of expansion since the last quarter of FY 2011-12 driven by robust factory, services and mining output, government data showed on Friday. In Q4 FY 2013-14, the economy grew by 4.6 per cent from the same period a year ago. Investors will be eying the current account deficit data due this week. Auto stocks will be in focus as companies release August sales numbers. However, cautious sentiment ahead of the Supreme Court verdict on the fate of all coal blocks allocated since 1993 may trim gains in the Sensex. The apex court last week held that all coals blocks allocated since 1993 were illegal and will decide whether to undertake a mass cancellation of blocks allocated since 1993 or slap some sort of penalty.
