Why is VST Industries falling/rising?

As of 01-Jul, VST Industries Ltd's stock price is currently at 314.70, reflecting an increase of 7.15, or 2.32%. The stock has been on an upward trend, gaining for the last eight days and achieving a total return of 12.39% during this period. It opened with a gain of 2.42% today and reached an intraday high of Rs 317.85. Despite this positive movement, the company faces challenges, including a negative growth rate in operating profit over the last five years and declining profits of -31.1% over the past year. Additionally, the stock has underperformed against its peers and the broader market over the long term, with a return of -14.42% in the last year. The recent rise in stock price may be attributed to increased investor participation, as evidenced by a significant rise in delivery volume.
In the broader market context, VST Industries has outperformed the Sensex in the short term, with a 1-week return of +9.65% compared to the Sensex's +2.00%. However, the company has consistently underperformed against the benchmark over the last three years, which may raise concerns among investors. While the stock's recent performance is encouraging, the overall negative financial indicators and declining institutional investor participation suggest caution moving forward.
