Why is Alkali Metals falling/rising?

As of 10-Sep, Alkali Metals Ltd's stock price is currently at Rs 89.76, reflecting a decrease of Rs 2.76 or 2.98%. Today's price summary indicates that the stock opened with a gain of 3.71% but has since fallen, marking a trend reversal after two consecutive days of gains. The stock has underperformed its sector by 3.56%, and while it has shown a positive return of 3.63% over the past week, it has a significant year-to-date decline of 19.64%. The company has reported positive net sales growth of 40.49% in the last quarter, but it faces challenges with weak long-term fundamental strength, including a -198.56% CAGR growth in operating profits over the last five years and a low return on equity of 3.08%. Additionally, 30.06% of promoter shares are pledged, which can exert downward pressure on the stock price in a falling market.
In the broader market context, Alkali Metals' recent performance contrasts with the benchmark Sensex, which has gained 1.06% over the past week. While the stock has shown some short-term resilience, its long-term performance has been lackluster, with a 28.11% decline over the past year compared to a slight decrease of 0.61% for the Sensex. The stock's liquidity appears adequate, but the significant pledge of promoter shares and the company's inability to generate consistent operating profits contribute to a perception of risk among investors, further influencing its price decline.
