Why is United Breweries falling/rising?

As of 17-Sep, United Breweries Ltd. is experiencing a decline in its stock price, currently at 1,800.00, which reflects a decrease of 32.1 or 1.75%. The stock has underperformed its sector by 2.54% today and is close to its 52-week low, just 1.33% away from Rs 1,776. Over the past month, the stock has dropped by 6.58%, and its year-to-date performance shows a decline of 11.68%. Despite a healthy long-term growth rate in operating profit of 27.77% and positive financial results in June, the stock's valuation appears expensive with a Price to Book Value of 10.9, leading to concerns among investors. Additionally, the stock has consistently underperformed against the benchmark over the last three years, generating a return of -13.65% in the past year.
In the broader market context, the Sensex has shown a positive return of 1.56% over the past week, contrasting sharply with United Breweries' stagnant performance of 0.00% in the same period. This underperformance highlights the stock's struggle to attract investor confidence, especially given its high institutional holdings of 24.26%, which typically indicate a more informed investor base. The stock's recent trend reversal, following three days of gains, coupled with a relatively low delivery volume increase of 23.67% against the five-day average, suggests a lack of sustained buying interest. Overall, the combination of high valuation concerns and consistent underperformance against benchmarks is contributing to the stock's current decline.
