Mumbai | Due to selling in bank, finance and telecom stocks, the domestic stock market could not maintain the initial gains on Wednesday. The Sensex fell 344 points to close at a five- month low of 57,556. NSE’s Nifty also fell 71 points to 16,972. According to traders, concerns over the health of banks and high retail inflation influenced the market sentiment during the trading session. Apart from this, the continuous withdrawal of foreign capital from the Indian market and the fall in the rupee also put pressure on the market. According to experts, the gains made in the morning could not be sustained due to weakness in the European markets. The European Central Bank (ECB) is scheduled to meet on Thursday. In this, interest rates are expected to increase by at least 0.25%. Due to this, weakness was seen in the markets of Europe. High interest rates are a matter of concern for the stock markets.
