Why is VST Till. Tract. falling/rising?

As of 19-Sep, VST Tillers Tractors Ltd is experiencing a decline in its stock price, currently at Rs 5,227.00, reflecting a decrease of Rs 28.0 or 0.53%. The stock has been losing value for the last two days, with a total drop of 1.19% during this period. Today's performance shows that it has outperformed its sector by 1.88%, despite the overall negative trend. The stock touched an intraday low of Rs 5,125.95, indicating a significant drop of 2.46%. Over the past week and month, the stock has underperformed against the benchmark Sensex, with returns of -0.08% and -0.44%, respectively, while the Sensex has gained 0.88% and 1.20%. While the company has a low debt-to-equity ratio and has shown healthy long-term growth in operating profit, the stock's valuation appears expensive with a Price to Book Value of 4.5, which may be contributing to the recent price decline.
In the broader market context, the stock's short-term performance is lagging behind the Sensex, which has seen positive returns, contrasting with VST Tillers Tractors Ltd's recent struggles. The sector, specifically Automobiles-Tractors, has also faced a downturn, falling by 2.33%. Additionally, there has been a notable decrease in investor participation, with delivery volume dropping by 56.75% compared to the five-day average, which may indicate waning interest among investors. Despite the company's strong fundamentals and high institutional holdings, these factors combined with the broader market trends are likely influencing the stock's current downward movement.
