Why is United Spirits falling/rising?

As of 05-Aug, United Spirits Ltd is experiencing a decline in its stock price, currently at Rs 1,323.90, which reflects a decrease of Rs 15.65 or 1.17%. The stock has underperformed its sector by 0.99% today and is 4.03% away from its 52-week low. Over the past week, the stock has seen a slight decrease of 0.05%, while its performance over the last month shows a more significant drop of 3.95%. Despite having a high management efficiency indicated by a return on equity (ROE) of 17.23% and a low debt-to-equity ratio, the company has faced challenges with poor long-term growth, as evidenced by a modest annual sales growth rate of 5.29% and a flat performance in its latest quarterly results. Additionally, the stock is trading at a premium compared to its peers, which may deter potential investors.
In the broader market context, the Sensex has declined by 0.77% over the past week, indicating a slightly negative sentiment in the market. However, United Spirits' year-to-date performance shows a stark contrast, with a decline of 18.55% compared to the Sensex's increase of 3.29%. This significant underperformance suggests that the stock is facing specific challenges that are not affecting the broader market. The falling investor participation, as indicated by a decrease in delivery volume, further highlights the lack of confidence among investors, which is contributing to the stock's downward trend.
