Mumbai: The BSE benchmark Sensex continued its downslide for the fourth week in a row, shedding another 140 points to finish at 16,152.75 due to persistent selling pressure in view of various negative external as well as internal factors. Global debacle on eurozone worries amid rupee falling to fresh historic low cast a pall over the benchmark Sensex which tumbled below 16,000-mark after four months. The main reason for the world stock markets disaster was Greece which failed to form a government, pushing the country to new elections amid concerns that elections will ultimately lead to the country leaving the eurozone, sending global stocks to a tail-spin. Asian shares fell steeply on eurozone debt worries after more signs emerged of growing instability among Spanish banks and political turmoil in Greece with the latest sluggish economic data from the United States adding to the list of risks for investors. Internal factors like rise in inflation (WPI), retail inflation and fiscal deficit amid falling Indian rupee to a new historic low further aggravated the situation. High inflation dashed hopes of rate cut by the central bank. Inflation, as measured by the Wholesale Price Index (WPI), moved up to 7.23 percent in April from 6.89 percent in March on account of spurt in prices of vegetables, meat, milk and pulses, although onion and fruits showed a declining trend. Retail inflation also spurted to double digit mark to 10.36 percent in April from 9.38 percent in March. Fresh capital outflows too added to the woes, a broker said, adding that more outflows are expected in near term looking at the bearish tone of the market. Sustained fall in the rupee to a new historic low to 54.91 during intra-day trading also hurt the market sentiment as importers continued to bear the brunt as depreciating rupee raises import costs, thereby impacting their bottomline. The BSE 30-share barometer resumed higher at 16,318.36 but declined afterwards to a 19-week low of 15,809.71, before bouncing back on excellent SBI Q4 results announced Friday to settle at 16,152.75, still showing a loss of 140.23 points or 0.86 percent from its last weekend's level. Similarly, the NSE broad-based Nifty also touched a low of 4,788.95, before recovering to settle at 4,891.45, still showing a loss of 37.45 points of 0.76 percent. Selling was seen in auto, consumer durable, power, refinery, PSU, capital goods and banking sectors. However, FMCG counters were in demand after weather department early this week forecast that the southwest monsoon will arrive in time. Fall in heavyweights like Tata Motors, BHEL, Maruti Suzuki, Hindalco, Coal India, HDFC Bank, ONGC, HDFC, NTPC, Tata Steel and few others mainly weighed on the Sensex. Contrary to the market sentiment, country's second software exporter Infosys ended with 3.18 percent gains after a member of company's board yesterday said early signs of business picking up in the world's largest economy US. Construction and engineering giant from capital goods, L&T also spurted by two per cent after strong Q4 results and also robust future outlook.
