Top stocks to buy: Market benchmark Nifty 50 traded lacklustre intraday on Tuesday, 27 October, after snapping its four-day losing streak in the previous session.The index touched an intraday high and low of 22,804 and 22,653, respectively, on Tuesday, indicating a lack of momentum in the market.According to Vishnu Kant Upadhyay, AVP- Research at Master Capital Services, the broader technical structure remains weak, with Nifty continuing to trade below its key short-term moving averages and the formation of lower highs and lower lows reinforcing the prevailing bearish bias."On the upside, 22,800-23,000 remains a crucial resistance zone, and a sustained move above this range could attract fresh buying.
