Why is Electrotherm(I) falling/rising?

As of 16-Sep, Electrotherm (India) Ltd is experiencing a price increase, with the current price at Rs 996.00, reflecting a rise of Rs 7.3 or 0.74%. Today's price summary indicates that the stock has outperformed its sector by 0.57% and has gained after two consecutive days of decline. Although the stock opened with a loss of 3.8%, it reached an intraday high of Rs 1009.75, showcasing some volatility. The stock has shown a strong performance over the past month with a return of 25.83%, significantly outpacing the Sensex's 2.21% increase. However, it has a negative long-term outlook due to a weak fundamental strength characterized by a negative book value and declining net sales and profits over the last four quarters.
In the broader market context, the stock's short-term performance is notably stronger than the benchmark, as it has gained 4.32% over the past week compared to the Sensex's 1.58% increase. Despite this recent uptick, the stock's year-to-date performance remains negative at -19.32%, contrasting with the Sensex's positive return of 5.43%. The increase in institutional investor participation, which has risen by 0.67% in the last quarter, may provide some support for the stock; however, the overall financial health of the company raises concerns, particularly given its high debt levels and negative results over recent quarters.
