New Delhi: After opening with modest gains, Nifty snapped a two-session rally and closed at month’s low, HDFC Securities head of retail research Deepak Jasani said on Monday. “Finally, Nifty fell 0.91 per cent or 197.8 points to 21513,” Jasani said. The effective market volume at NSE was again below Rs 1 lakh crore, reflecting weak sentiments. The small capitalization index fell 0.36 percent, outperforming the Nifty, even as the expected decline index fell sharply to 0.64:1.
