Why is Neuland Labs. falling/rising?

As of 18-Sep, Neuland Laboratories Ltd is experiencing a decline in its stock price, currently at Rs 15,900.00, which represents a decrease of Rs 340.0 or 2.09%. Today's price summary indicates that the stock has underperformed its sector by 3.14% and has fallen after two consecutive days of gains, touching an intraday low of Rs 15,760, which is a 2.96% drop. Despite this recent decline, the stock has shown strong performance over the past year, generating a return of 25.33%, and has significantly outperformed the BSE500 in each of the last three annual periods. The company maintains a low Debt to EBITDA ratio of 0.57 times, indicating a strong ability to service debt, and has high institutional holdings at 33.66%, which suggests confidence from more sophisticated investors.
In the broader market context, Neuland Laboratories has delivered a 2.22% return over the past week, outperforming the Sensex, which gained 1.80% in the same period. However, the stock's recent price drop may be attributed to falling investor participation, as evidenced by a significant decrease in delivery volume by 73.08% compared to the five-day average. While the stock remains liquid enough for trading, the decline in participation could indicate a lack of confidence among investors, contributing to the current downward movement despite the company's strong historical performance and fundamentals.
