Why is Shantai Indust. falling/rising?

As of 23-Jun, Shantai Industries Ltd is experiencing a decline in its stock price, currently at 13.01, which reflects a decrease of 0.59 or 4.34%. The stock has been underperforming significantly, with a consecutive fall over the last six days resulting in a total decline of 14.01%. Additionally, it has underperformed its sector by 4.87% today. Despite a strong performance over the past year with a return of 75.81%, the stock has shown negative returns of 13.27% over the past week and 11.92% over the past month. The company's recent financial results indicate positive growth, with the highest quarterly profits reported, but its long-term fundamental strength is weak, as evidenced by a low return on equity and poor sales growth.
In the broader market context, while Shantai Industries has outperformed the benchmark index over the past year, the recent short-term performance has been unfavorable compared to the Sensex, which has shown a slight increase of 0.12% over the past week. The stock's liquidity appears adequate, but a notable drop in investor participation, with a 25.99% decrease in delivery volume, suggests waning interest among investors. This combination of short-term underperformance, declining investor engagement, and weak long-term fundamentals contributes to the stock's current downward trajectory.
