Why is Share India Sec. falling/rising?

As of 19-Sep, Share India Securities Ltd is experiencing a decline in its stock price, currently at 142.50, which reflects a decrease of 1.4 or 0.97%. The stock has been underperforming, having fallen consecutively for the last four days, resulting in a total decline of 3.06% during this period. Additionally, the stock has underperformed its sector by 0.82% today and has shown significant negative returns over various periods, including a 10.66% drop over the last month and a staggering 53.45% year-to-date. The company has also reported negative results for the last three consecutive quarters, with net sales and profits declining significantly, which has contributed to the stock's downward movement. Furthermore, over half of the promoter shares are pledged, adding pressure to the stock price in a falling market.
In the broader market context, the stock's performance has been notably worse than the benchmark, with the Sensex gaining 0.88% over the past week while Share India Securities Ltd has lost 2.20%. This trend of underperformance continues over the past year, where the stock has declined by 52.75% compared to a slight negative return of 0.67% for the Sensex. Despite some positive long-term fundamentals, such as a strong return on equity and healthy growth rates, the recent financial results and high levels of pledged shares have overshadowed these strengths, leading to a lack of investor confidence and further declines in stock price.
