Why is Vinati Organics falling/rising?

As of 04-September, Vinati Organics Ltd is currently priced at Rs 1,734.70, reflecting an increase of Rs 18.0 or 1.05%. The stock has shown positive momentum recently, gaining for the last three days with a total return of 3.01% during this period. However, over the past month, the stock has declined by 2.25%, and its year-to-date performance is down by 3.62%. Despite these declines, the company demonstrates strong management efficiency with a high return on equity (ROE) of 16.68% and a low debt-to-equity ratio of 0.01, which may contribute positively to investor sentiment. Nonetheless, there is a notable decrease in investor participation, as evidenced by a 48.55% drop in delivery volume compared to the five-day average.
In the broader market context, the stock's performance over the past week has lagged slightly behind the benchmark Sensex, which has increased by 0.80% compared to Vinati Organics' 0.38%. This underperformance in the longer term is also evident, with the stock down 9.56% over the past year while the Sensex has only declined by 1.98%. The stock's recent gains may be seen as a corrective movement after a period of underperformance, but the overall trend indicates challenges in maintaining upward momentum against a backdrop of declining investor participation and weaker returns relative to the benchmark.
