The key domestic benchmarks may witness a positive opening today tracking a bullish trend in major Asian markets. Asian stocks rose as muted Chinese inflation gave policymakers more room to inject stimulus to bolster the world’s second biggest economy. China’s consumer price index climbed 2 per cent in August 2014 from the same month a year ago, the lowest in four months, and down from an annual rise of 2.3 per cent in July 2014. China’s Shanghai Composite and Hang Seng were trading higher while Japan’s Nikkei 225 extended gains as a weaker yen boosted the appeal of exporter stocks. Back home, the Sensex may continue to witness some profit booking at existing levels after surging to record highs in recent weeks, curbing gains. Caution ahead of the IIP and CPI data due tomorrow may also weigh on Dalal Street.
