The Indian stock market sentiment has turned nervous as the Nifty 50 index corrected below key support levels, approaching the 200-period moving average at 25,000. Immediate support is seen at the 100-period MA around 25,500. Analyst Vaishali Parekh of Prabhudas Lilladher notes significant profit booking and anticipates intensified selling pressure if the 25,500 level is breached, indicating a precarious market position.
