Oversold stocks can provide investment opportunities for savvy investors, and the Relative Strength Index (RSI) is a popular indicator for identifying them. ETMarkets has listed eight stocks with an RSI below 30 and a market cap over Rs 100 crore, including Indian Energy Exchange and D P Abhushan. It's important to conduct thorough research and analysis before making investment decisions, taking company fundamentals, industry outlook, market conditions, and personal risk tolerance and goals into account.
