MUMBAI (Reuters) - The BSE Sensex fell for a fifth consecutive session on Tuesday to mark its weakest start to a year since 2011, as technology stocks, including Infosys Ltd, dropped on caution ahead of the software exporter's quarterly results on Friday.
Concerns that foreign investors are becoming more selective are also weighing on sentiment, after their $20 billion worth of net purchases last year helped boost domestic shares.
Foreign institutional investors (FIIs) sold 10.04 billion rupees worth of index futures and 3.33 billion rupees worth of cash shares over the previous two sessions. However, they still remain net buyers of 7.37 billion rupees of cash shares so far this year.
Losses also tracked Asian shares that fell to a near four-month low on Tuesday on disappointing U.S. services sector data that raised concerns about stuttering growth in the world's largest economy.
Markets are expected to remain range-bound ahead of Infosys Ltd's (INFY.NS) third quarter earnings, informally kicking off the results season, and key inflation data next week.
"The Sensex would remain in a range of 500-600 points for the time being as fiscal problems remain a drag, even as inflation data may surprise positively," said Aneesh Srivastava, chief investment officer at IDBI Federal Life Insurance.
The Sensex fell 0.45 percent, or 94.06 points, to end at 20,693.24, marking its lowest close since December 17.
The index has fallen 2.2 percent this year, registering a loss in each of the five trading sessions so far. That would make it the weakest start since a 4 percent fall over the first five sessions of 2011.
The Nifty lost 0.47 percent, or 29.20 points, to end at 6,162.25, approaching 6,100 which has been a key technical support five times since January 2013.
Power producers slumped for a second day on media reports that the state government in Maharashtra, home to Mumbai, was planning to cut power tariffs.
Among the gainers, tyremakers rose on expectations of higher margins as the key Tokyo Commodity Exchange rubber contract hit a five-week low on Tuesday, weighed down in part by weak Chinese services sector data.
ICICI Bank (ICBK.NS) also gained 0.9 percent on value-buying after falling nearly 5.3 percent over the previous four sessions, dealers said.
