Why is Tarapur Trans falling/rising?

As of 25-Jun, Tarapur Transformers Ltd is experiencing a decline in its stock price, currently at 28.46, which represents a decrease of 0.58 or 2.0%. The stock has underperformed its sector today by 1.73% and has been on a consecutive downward trend for the last four days, accumulating a total drop of 7.72% during this period. Despite a strong performance over the past year with a return of 100.71%, the stock's recent struggles are compounded by a negative book value and a high Debt to EBITDA ratio, indicating weak long-term fundamental strength. Additionally, 94.7% of promoter shares are pledged, which can exert further downward pressure in a declining market.
In the broader market context, the stock's short-term performance has significantly lagged behind the benchmark, with a 1-week return of -5.89% compared to the Sensex's gain of 1.61%. While the stock has shown impressive returns over longer periods, such as 639.22% over three years, the recent negative trends and falling investor participation, evidenced by a 91.94% drop in delivery volume, suggest a lack of confidence among investors. This combination of factors indicates that the stock is facing significant challenges despite its historical performance.
