Why is Shankara Build. falling/rising?

As of 29-Aug, Shankara Building Products Ltd is experiencing a slight decline in its stock price, currently at 925.95, reflecting a change of -0.05 (-0.01%). The stock has been on a downward trend, losing 19.13% over the last five days and showing a significant decline of 18.10% over the past month. Despite this recent downturn, the company has demonstrated strong long-term growth, with net sales increasing at an annual rate of 20.85% and a remarkable net profit growth of 101.87% reported in June. However, the recent reduction in promoter stake by 9.07% may indicate a lack of confidence in the company's future, contributing to the stock's current price movement.
In the broader market context, Shankara Building Products Ltd's performance has been notably better than the benchmark, as it has generated a return of 55.40% over the past year, while the BSE500 index has seen a decline of 5.40%. However, in the short term, the stock's performance has been poor compared to the benchmark, with a 10.48% drop over the past week against the Sensex's decline of only 1.84%. This disparity highlights the stock's recent struggles despite its strong fundamentals and historical performance, suggesting that investor sentiment may be weighing heavily on its current valuation.
