Why is VST Till. Tract. falling/rising?

As of 12-Sep, VST Tillers Tractors Ltd is experiencing a decline in its stock price, currently at Rs 5,231.25, which reflects a decrease of Rs 58.45 or 1.1%. The stock has underperformed its sector by 0.91% today and has been on a consecutive downward trend for the last three days, resulting in a total decline of 3.04%. Additionally, the stock touched an intraday low of Rs 5,172.1, indicating a significant drop. Despite showing positive long-term growth with a 22.23% return over the past year and a healthy operating profit growth rate of 115.64%, the stock's recent performance is hampered by falling investor participation, as evidenced by a 51.83% drop in delivery volume compared to the five-day average.
In the broader market context, the stock's short-term performance has lagged behind the benchmark, with a 1-week return of -0.72% compared to the Sensex's gain of 1.48%. While the stock has historically outperformed the BSE500 over longer periods, its current valuation appears expensive with a Price to Book Value of 4.5 and a relatively low return on equity of 9.3%. This combination of high valuation metrics and recent underperformance may be contributing to investor caution, leading to the observed decline in stock price.
