Why is VST Till. Tract. falling/rising?

As of 18-Sep, VST Tillers Tractors Ltd is experiencing a decline in its stock price, currently at 5,255.00, reflecting a decrease of 35.0 points or 0.66%. The stock has underperformed its sector by 3.69% today and has fallen after two consecutive days of gains. Although the stock is trading above its 50-day, 100-day, and 200-day moving averages, it is below its 5-day and 20-day moving averages. Over the past week, the stock has seen a slight decline of 0.66%, while its year-to-date return stands at 0.67%. Despite a robust annual growth in operating profit and a strong performance in the last year, the stock's valuation appears expensive with a Price to Book Value of 4.5, which may be contributing to the recent price drop.
In the broader market context, the stock's recent performance contrasts with the Sensex, which has gained 1.80% over the past week. The automobile-tractor sector has also seen a positive movement, gaining 3.02%. While VST Tillers Tractors Ltd has shown strong long-term growth and high institutional holdings, the recent decline may be influenced by its relatively high valuation metrics and the market's overall positive sentiment towards the sector. The rising investor participation, indicated by an increase in delivery volume, suggests that there is still interest in the stock, but the current price movement reflects a cautious sentiment among investors in light of its recent performance and valuation concerns.
