Why is VST Till. Tract. falling/rising?

As of 11-Sep, VST Tillers Tractors Ltd is experiencing a decline in its stock price, currently at 5,289.70, reflecting a decrease of 69.4 points or 1.29%. The stock has underperformed its sector by 1.9% today and has seen a consecutive fall over the last two days, with a total decline of 1.95%. Despite this recent downturn, the stock has shown positive performance over the past month, with a return of 9.90%, and has outperformed the benchmark Sensex over the last year with a return of 22.53%. However, the stock is facing challenges such as a significant drop in delivery volume, which has decreased by 35.36% against the 5-day average, indicating falling investor participation.
In the broader market context, while VST Tillers Tractors Ltd has underperformed in the short term, the Sensex has gained 1.03% over the past week. The company benefits from a low debt-to-equity ratio and strong long-term growth metrics, with operating profit growing at an annual rate of 115.64%. However, the stock's valuation appears expensive with a price-to-book value of 4.6, and its return on equity stands at 9.3. Despite generating a solid return over the past year, the profit growth has been modest at 4.3%, contributing to a high PEG ratio of 9.4, which may be causing some investor caution in the current market environment.
