The Gujarat Mineral Development Corporation (GMDC) soared by 20% with high volumes, opening up the possibility of hitting Rs 200 in the next six months, according to experts. Traders and investors should keep an eye on the stock and consider buying on dips to Rs 135-140. The stock is part of the S&P BSE Smallcap index and has been trading above short and long-term moving averages. The technical indicator MACD is also in a buy mode providing support for bulls, while a clear break above Rs 160 levels will open up fresh investment opportunities.
