Why is Quest Flow falling/rising?

As of 30-Jul, Quest Flow Controls Ltd is experiencing a price increase, currently at 394.90, which reflects a rise of 12.9 or 3.38%. The stock has shown a positive trend today, outperforming its sector by 2.77% and opening with a gain of 4.45%. After three consecutive days of decline, today's performance marks a potential trend reversal, with the stock reaching an intraday high of Rs 403, a 5.5% increase. However, despite this upward movement, the stock's year-to-date performance remains concerning, with a decline of 31.41%, and a significant drop of 67.50% over the past year. Additionally, there has been a notable decrease in investor participation, with delivery volume falling by 31.82% compared to the five-day average, indicating a potential lack of sustained interest.
Broader market context shows that while Quest Flow has gained 1.06% over the past month, the benchmark Sensex has declined by 2.54% during the same period, suggesting that the stock's recent rise is somewhat isolated from broader market trends. In the short term, the stock's performance has been better than the benchmark, which has seen a 1.03% decline over the past week compared to Quest Flow's slight decrease. However, the significant long-term underperformance of the stock, particularly its 67.50% drop over the last year against a nearly flat Sensex, raises questions about the sustainability of today's gains amidst broader market conditions.
