Why is Shankara Build. falling/rising?

As of 26-Sep, Shankara Building Products Ltd is experiencing a decline in its stock price, currently at Rs 212.70, which reflects a decrease of Rs 11.15 or 4.98%. The stock has underperformed its sector by 2.23% today and has been on a consecutive downward trend for the last two days, resulting in a total decline of 9.72%. It opened with a loss of 4.98% and has not traded outside this price range. Additionally, the stock is trading below all its moving averages, indicating a bearish trend. Despite a strong long-term performance with a year-to-date increase of 29.47% and a remarkable 68.94% rise over the past year, recent negative factors such as a significant drop in delivery volume and reduced promoter confidence, with a 9.07% decrease in their stake, have contributed to the stock's current downward movement.
In the broader market context, Shankara Building Products Ltd has underperformed compared to the benchmark Sensex, which has seen a decline of 2.66% over the past week and 0.45% over the past month. While the stock has shown strong growth in net sales and profitability, the recent negative sentiment in the construction materials sector, which has fallen by 2.81%, and the overall market's negative performance, with the BSE500 down by 7.63% in the last year, have likely influenced investor sentiment adversely. The combination of these factors has led to a decline in stock price despite the company's strong fundamentals.
