Why is S T C falling/rising?

As of 19-Sep, the State Trading Corporation of India Ltd is experiencing a decline in its stock price, currently at 123.50, reflecting a decrease of 0.85 or 0.68%. Today's price summary indicates that the stock's performance is in line with its sector, although it is trading higher than its 5-day and 20-day moving averages but lower than its 50-day, 100-day, and 200-day moving averages. The stock has shown a mixed performance over various periods, with a 1-week return of +2.92% but a year-to-date decline of -18.62%. The company faces significant challenges, including a negative book value, high debt levels, and poor long-term growth metrics, which contribute to its weak fundamental strength and negative sentiment among investors.
In the broader market context, the stock's recent performance contrasts with the benchmark Sensex, which has gained 0.88% over the past week. Despite a short-term uptick, the stock has underperformed significantly over the longer term, with a 1-year return of -31.69% compared to a slight decline of -0.67% for the Sensex. Additionally, the falling investor participation, as evidenced by a 43.42% drop in delivery volume, suggests a lack of confidence in the stock, further exacerbated by the absence of domestic mutual fund investment, indicating that institutional investors may also be wary of the company's prospects.
