Why is Switching Tech. falling/rising?

As of 23-Oct, Switching Technologies Gunther Ltd is experiencing a significant rise in its stock price, currently at Rs 52.80, reflecting an increase of Rs 8.62 or 19.51%. The stock has outperformed its sector by 20.27% today and has shown a consecutive gain over the last two days, with a total return of 22.71% during this period. It opened with a substantial gain of 19.99% and reached an intraday high of Rs 53.01. However, despite this positive short-term performance, the company has a negative book value and weak long-term fundamental strength, with net sales declining at an annual rate of -3.77% over the past five years. Additionally, the company carries high debt, reflected in its debt-to-equity ratio, and has shown poor long-term growth, which may contribute to the stock's volatility and risk perception among investors.
In the broader market context, the stock's short-term return of +3.71% over the past week significantly outpaces the Sensex, which has only increased by 1.30% in the same timeframe. However, the stock has underperformed the benchmark over longer periods, with a -30.75% return over the past year compared to the Sensex's +5.59%. This disparity highlights the stock's recent volatility and investor sentiment, which may be influenced by its recent gains despite a backdrop of poor long-term performance and fundamental concerns.
