Why is Tilaknagar Inds. falling/rising?

As of 17-Sep, Tilaknagar Industries Ltd is experiencing a decline in its stock price, currently at 470.85, which reflects a decrease of 9.35 points or 1.95%. Today's price summary indicates that the stock underperformed its sector by 2.74%, with an intraday low of Rs 467.75. Despite a strong long-term growth trajectory, evidenced by a 121.05% increase in net profit and consistent positive results over the last five quarters, the stock's recent performance has been affected by its high valuation metrics, including a Price to Book Value of 10.3, and the increased proportion of pledged promoter shares, which now stands at 35%. Additionally, while the stock has shown impressive returns over the past year and three years, its short-term performance has lagged behind the benchmark, with a 6.54% decline over the last month compared to a 2.60% increase in the Sensex.
In the broader market context, Tilaknagar's recent performance contrasts sharply with the benchmark, as it has underperformed significantly in the short term, with a 1-week return of -0.06% compared to the Sensex's 1.56% gain. This underperformance may be exacerbated by the current market conditions, where high levels of pledged shares can lead to increased selling pressure, particularly in a declining market. Despite the stock's strong historical returns and growth metrics, the combination of high valuation and market sentiment appears to be contributing to its current downward price movement.
