Why is TV Vision falling/rising?

As of 22-Sep, TV Vision Ltd is experiencing a decline in its stock price, currently at 6.52, reflecting a decrease of 0.34 or 4.96%. The stock has underperformed its sector by 5.18% today and has been on a consecutive downward trend for the last three days, resulting in a total drop of 14.44%. Additionally, the stock is trading below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages. The delivery volume has also seen a significant decline, falling by 49.84% against the 5-day average, indicating reduced investor participation. The stock's performance over various periods shows a substantial year-to-date decline of 69.30% and a one-year drop of 47.76%, which is considerably worse than the benchmark Sensex's performance.
In the broader market context, the stock's short-term performance has been notably poor compared to the Sensex, which has gained 0.46% over the past week while TV Vision has lost 9.07%. The company's financial health is concerning, with a negative book value and a high debt-to-equity ratio, leading to weak long-term fundamentals. The company has reported negative results for the last three consecutive quarters, with a significant decline in net sales and a negative EBITDA, further contributing to the stock's downward pressure. Additionally, the fact that 50.82% of promoter shares are pledged adds to the risk, especially in a falling market, which can exacerbate the stock's decline.
