Why is SEL Mfg. Co falling/rising?

As of 13-Aug, SEL Manufacturing Company Ltd is experiencing a decline in its stock price, currently at 30.00, reflecting a decrease of -0.39 or -1.28%. The stock has underperformed its sector by -1.62% today and has been on a downward trend for the last two days, with a total decline of -2.98% during this period. Over the past week, the stock has also seen a return of -1.28%, while its performance over the last month shows a significant drop of -13.89%. The company has reported negative results for the last four consecutive quarters, with net sales and profit after tax both declining by 81.52%. Additionally, the company has a negative book value and a high debt-to-equity ratio, which contributes to its weak long-term fundamental strength and overall riskiness.
In the broader market context, the stock's recent performance contrasts sharply with the benchmark, as the Sensex has only decreased by -0.01% over the same week. This consistent underperformance against the benchmark is evident over the last three years, where the stock has generated a return of -55.60%, while the BSE500 has shown positive growth. The falling investor participation, indicated by a 67.14% drop in delivery volume, further exacerbates the stock's decline. The presence of pledged promoter shares adds additional downward pressure, particularly in a falling market, highlighting the stock's vulnerability and contributing to its current negative trajectory.
