Why is Tilaknagar Inds. falling/rising?

As of 28-Aug, Tilaknagar Industries Ltd is experiencing a decline in its stock price, currently at 472.65, reflecting a decrease of 1.65 (-0.35%). The stock has been underperforming recently, with a consecutive fall over the last three days resulting in a total drop of 3.28%. In the past week, the stock has decreased by 2.80%, and over the last month, it has fallen by 7.16%. Despite a strong performance year-to-date with an 11.90% increase and an impressive 80.64% rise over the past year, the stock's recent movement is influenced by a significant drop in investor participation, as evidenced by a 58.07% decline in delivery volume compared to the five-day average. Additionally, while the stock has shown healthy long-term growth with a 36.43% annual increase in operating profit and positive results over the last five quarters, the high valuation indicated by a Price to Book Value of 10.4 and the increase in pledged promoter shares are contributing to the downward pressure on the stock.
Broader market context indicates that Tilaknagar Industries Ltd's recent performance is not isolated, as it has underperformed the Sensex, which has only seen a 2.34% decline over the past week. The stock's short-term struggles contrast with its long-term success, where it has outperformed the BSE500 over various periods, including a remarkable 521.50% increase over the last three years. However, the current market conditions, characterized by falling investor participation and high valuations, are creating a challenging environment for the stock, leading to its recent price decline.
