MUMBAI The BSE Sensex fell 1.6 percent on Monday to its lowest close this month, as jitters national elections may produce a split verdict sparked profit taking after a near 50 percent rally since early March.
Investors are worried neither the ruling Congress party coalition or the main opposition Bharatiya Janata Party-led group will win a clear majority on its own, leaving the possibility of a loose coalition of regional parties.
"The critical question for markets is will the election result in a stable government," Tushar Poddar, an analyst at Goldman Sachs, said.
The election results are due on Saturday, and exit polls after the month-long elections end on Wednesday are expected to keep trading volatile this week.
Energy giant Reliance Industries and government-run State Bank of India led the main index lower, but private-sector lenders ICICI Bank and HDFC Bank bucked the trend and rose.
The 30-share BSE index fell 1.63 percent, or 193.44 points, at 11,682.99, its lowest close since April 29 and followed a 2 percent drop on Friday.
The benchmark, which initially rose 1.3 percent, is still up 45.2 percent from its 2009 low in early March. Twenty-four of its components dropped, while in the broader market losers led gainers almost 2 to 1 on moderate volume of 409.4 million shares.
If a relatively stable coalition comes to power, shares are expected to resume their upward move as longer-term factors bode well for the Indian market.
"History suggests that as long as a stable coalition comes to power, the impact on sentiment and activity is likely to be positive," Poddar said.
Reliance Industries, which has the biggest weight in the main index, fell 2 percent to 1,859.35 rupees, while State Bank of India shed 4.9 percent to 1,260.70 rupees.
Private-sector lender ICICI Bank rose 0.6 percent to 523.45 rupees, while rival HDFC Bank edged up 0.1 percent at 1,144.80 rupees.
The 50-share NSE index fell 1.8 percent to 3,554.60 points.
