Why is Switching Tech. falling/rising?

As of 04-Jul, Switching Technologies Gunther Ltd is experiencing a decline in its stock price, currently at 81.00, which reflects a decrease of 0.75 or 0.92%. The stock has underperformed its sector today by 0.79%, and its delivery volume has significantly dropped by 98.45% compared to the 5-day average, indicating falling investor participation. Over the past week, the stock has decreased by 1.44%, while it has shown a modest increase of 1.50% over the past month. However, the stock's long-term fundamentals are concerning, with a negative book value and poor growth metrics, including a net sales decline of 9.98% annually and an operating profit drop of 210.22% over the last five years.
In the broader market context, the Sensex has decreased by 0.74% over the past week, which suggests that the stock's short-term performance is slightly worse than the benchmark. Despite the stock's impressive long-term gains of 119.81% over three years and 236.10% over five years, the recent negative trends in profitability and high debt levels raise significant concerns. The company's return on capital employed (ROCE) is at its lowest, and it is trading at a risky valuation compared to historical averages, contributing to the stock's current downward movement.
