Why is Vinati Organics falling/rising?

As of 12-Sep, Vinati Organics Ltd is currently priced at 1,706.30, reflecting an increase of 7.4 or 0.44%. Today's price summary indicates that the stock has gained after two consecutive days of decline, although it underperformed its sector by 0.44%. The stock's performance over the past week shows a slight increase of 0.10%, while it has risen by 3.56% over the past month. However, it has struggled in the longer term, with a year-to-date decline of 5.20% and a significant drop of 27.21% over the past three years. The company boasts a high management efficiency with a return on equity (ROE) of 16.68% and a low debt-to-equity ratio of 0.01, but it faces challenges such as poor long-term growth and a very expensive valuation with a price-to-book ratio of 6.3.
In the broader market context, the stock's short-term return of 0.10% over the past week is significantly lower than the Sensex's return of 1.48% during the same period. Despite the recent uptick, Vinati Organics has consistently underperformed against the benchmark over the last three years, with a one-year return of -12.10% compared to the Sensex's -1.28%. This underperformance, coupled with flat results in June and a decline in investor participation, suggests that while there may be short-term gains, the stock faces ongoing challenges that could hinder its recovery in the longer term.
