Why is Diligent Media falling/rising?

As of 23-Sep, Diligent Media Corporation Ltd is experiencing a decline in its stock price, currently at 4.79, which represents a decrease of 0.13 or 2.64%. The stock has underperformed its sector by 1.78% today, following a trend reversal after two consecutive days of gains. Additionally, the stock's delivery volume has significantly decreased, falling by 56.93% against the 5-day average, indicating a drop in investor participation. Over the past year, the stock has generated a return of -26.19%, and its financial health is concerning, with a negative book value and a high debt-to-equity ratio. The company has shown poor long-term growth, with net sales growing at an annual rate of only 56.57% and an operating profit of 0% over the last five years.
In the broader market context, Diligent Media's short-term performance is slightly better than the benchmark, with a 1-week return of -0.21% compared to the Sensex's -0.34%. However, the stock has significantly underperformed over longer periods, including a -24.92% year-to-date return versus a +5.07% return for the benchmark. This underperformance, combined with the company's weak fundamentals and negative EBITDA, contributes to a perception of risk among investors, further exacerbating the stock's decline.
