Why is Hester Bios falling/rising?

As of 17-Sep, Hester Biosciences Ltd is experiencing a decline in its stock price, currently at Rs 2,050.00, which reflects a decrease of Rs 12.0 or 0.58%. The stock has underperformed its sector by 0.62% today and has traded within a narrow range of Rs 19.2. Over the past week, the stock has seen a decline of 2.80%, while its performance over the last year shows a significant drop of 16.47%. Despite a positive net profit growth of 145.1% and consistent positive results over the last five quarters, the company faces challenges such as a high Debt to EBITDA ratio of 3.49 times and low long-term growth rates in net sales and operating profit, which may contribute to investor concerns.
In the broader market context, the Sensex has increased by 1.56% over the past week, contrasting sharply with Hester Bios' decline. This underperformance is further highlighted by the stock's negative return of 16.47% over the past year, compared to the benchmark's slight decline of 0.46%. The lack of domestic mutual fund investment, which stands at 0%, may indicate a lack of confidence in the stock's valuation and future prospects, adding to the downward pressure on its price.
