Why is G M Breweries falling/rising?

As of 18-Aug, G M Breweries Ltd is experiencing a decline in its stock price, currently at 672.45, reflecting a decrease of 6.6 points or 0.97%. The stock has underperformed its sector by 0.39% today and is trading below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages. Over the past week, the stock has decreased by 0.53%, and it has shown a significant decline of 7.98% over the past month. Additionally, the stock has generated a return of -12.44% over the last year, with profits falling by 17%. The low investor participation, indicated by a 22.79% drop in delivery volume, further suggests a lack of confidence among investors.
In the broader market context, the Sensex has increased by 0.83% over the past week, contrasting with G M Breweries' decline. This underperformance is indicative of the stock's struggles, as it has lagged behind the benchmark in both short-term and long-term returns. The company's low debt-to-equity ratio and attractive valuation metrics, such as a 1.6 Price to Book Value, do not seem to be enough to offset the negative sentiment surrounding its poor growth prospects and declining profits. Furthermore, the absence of domestic mutual fund investment may reflect a lack of confidence in the company's future performance, contributing to the stock's downward trend.
