Why is Sastasundar Ven. falling/rising?

As of 10-Jul, Sastasundar Ventures Ltd is experiencing a decline in its stock price, currently at Rs 267.35, which reflects a decrease of Rs 8.85 or 3.2%. The stock has been on a downward trend, having fallen consecutively for the last 11 days, resulting in a total return of -14.56% during this period. Additionally, the stock's performance today underperformed its sector by 3.33%. Over the past year, Sastasundar has generated a return of -23.92%, significantly lagging behind the benchmark index, which has seen a modest gain of 4.09%. The company's financials indicate operating losses, with a net sales decline of 6.79% and a negative PBDIT, contributing to its weak long-term fundamental strength. Furthermore, the lack of domestic mutual fund investment suggests a lack of confidence in the stock's valuation.
In the broader market context, the stock's short-term performance has been notably poor compared to the benchmark, with a 1-week return of -7.49% against a negligible change in the Sensex. This consistent underperformance over the last three years, coupled with the company's negative operating profits and the significant drop in stock price, reflects a challenging environment for Sastasundar Ventures Ltd. The rising investor participation, indicated by increased delivery volume, does not seem to be enough to counteract the negative sentiment surrounding the stock, which is trading at risky levels compared to its historical valuations.
