Why is TV Vision falling/rising?

As of 25-Jun, TV Vision Ltd's stock price is currently at 7.19, reflecting a decrease of 0.14 or 1.91%. The stock has been underperforming significantly, having lost 18.67% over the last 12 days and is down 7.82% over the past week. Despite a positive return of 12.34% over the last month, the company's long-term fundamentals are weak, as indicated by a negative book value and declining net sales. The company has reported negative results for the last two consecutive quarters, with a significant drop in profit after tax and net sales, contributing to the stock's downward pressure. Additionally, 50.82% of promoter shares are pledged, which can exacerbate price declines in a falling market.
In the broader market context, the Sensex has gained 1.61% over the past week, contrasting sharply with TV Vision's recent performance. The stock's performance today has underperformed its sector by 4.83%, while the TV Broadcasting & Software sector has seen a gain of 2.97%. The stock's liquidity appears adequate, with a notable increase in delivery volume, but the overall negative sentiment surrounding the company's financial health and high debt levels continues to weigh heavily on its stock price.
