Why is VST Till. Tract. falling/rising?

As of 15-Jul, VST Tillers Tractors Ltd is experiencing a price increase, currently at 4,520.40, with a change of 51.7 or 1.16% up. The stock has shown strong performance over the past week, gaining 5.32%, and over the past month, it has risen by 19.05%. Despite today's performance underperforming the sector by 1.38%, the stock is trading above its moving averages across various time frames, indicating positive momentum. Additionally, the company has a low debt-to-equity ratio and has demonstrated healthy long-term growth, with operating profit increasing at an annual rate of 143.02%. High institutional holdings at 23.19% suggest confidence from knowledgeable investors, contributing to the stock's recent upward movement.
In the broader market context, while VST Tillers Tractors Ltd has outperformed the benchmark Sensex over the past week and month, it has a year-to-date return of -13.40%, contrasting with the Sensex's gain of 5.67%. This indicates that while the stock is currently rising, it has faced challenges earlier in the year. The sector, specifically Automobiles-Tractors, has gained by 2.54%, which may provide a supportive backdrop for the stock's recent performance. However, the significant drop in investor participation, with delivery volume falling by 68.1% against the 5-day average, raises concerns about the sustainability of this upward trend.
