Why is Share India Sec. falling/rising?

As of 18-Sep, Share India Securities Ltd is experiencing a decline in its stock price, currently at 143.90, reflecting a decrease of 1.6 or 1.1%. The stock has underperformed its sector by 1.43% today and has been on a consecutive downward trend for the last three days, resulting in a total decline of 2.11% during this period. Over the past week, the stock has dropped by 1.27%, and its performance over the last month shows a significant decline of 10.12%. The company has reported negative results for the last three consecutive quarters, with net sales falling by 17.57% and profits decreasing by 30.8%. Additionally, 52.61% of promoter shares are pledged, which adds downward pressure in a falling market.
In the broader market context, the stock's performance contrasts sharply with the Sensex, which has gained 1.80% over the past week and 2.14% over the past month. While the overall market has shown resilience, Share India Securities has significantly underperformed, with a year-to-date decline of 53.00% compared to the Sensex's increase of 6.24%. Despite strong long-term fundamentals, including a healthy growth rate in net sales and operating profit, the recent negative financial results and high promoter share pledges have contributed to the stock's poor performance relative to the market.
