Why is Vishnu Chemicals falling/rising?

As of 23-Sep, Vishnu Chemicals Ltd is currently priced at 495.30, reflecting a decrease of 6.7 points or 1.33%. The stock has underperformed its sector today by 0.77% and has experienced a trend reversal, falling after two consecutive days of gains. In the past week, the stock has declined by 1.10%, and over the last month, it has dropped by 4.02%. Despite a strong year-to-date return of 24.57%, the stock's recent performance is tempered by a decrease in delivery volume, which fell by 6.04% against the five-day average. The stock is trading at a discount compared to its peers, supported by high management efficiency and healthy long-term growth, but the recent decline suggests a shift in investor sentiment.
In the broader market context, the Sensex has seen a minor decline of 0.34% over the past week, indicating that the stock's short-term performance is lagging behind the benchmark. While Vishnu Chemicals has outperformed the market over the past year with a return of 24.70% compared to the Sensex's negative return of 3.33%, the current downward movement may reflect a broader market hesitation or profit-taking by investors. Additionally, the increase in institutional investor participation could suggest a more cautious approach from retail investors, contributing to the stock's recent decline.
