Why is ACC falling/rising?

As of 08-Aug, ACC Ltd's stock price is currently at 1,788.45, reflecting a decrease of 26.5 points or 1.46%. The stock has been experiencing a downward trend, having fallen for the last two days, resulting in a total decline of 2.3% during this period. It is also trading close to its 52-week low, just 0.75% away from Rs 1,775.05. Over the past month, the stock has underperformed significantly, with a return of -9.67%, compared to the Sensex's -4.60%. Despite a low debt-to-equity ratio and a relatively attractive valuation with a PEG ratio of 0.9, the company has reported flat results, with a significant drop in PAT for the last quarter, which may be contributing to the stock's decline.
In the broader market context, ACC's performance has been weaker than the benchmark, as evidenced by its -24.17% return over the past year compared to the Sensex's modest gain of 1.23%. The stock's consistent underperformance against the benchmark over the last three years, coupled with a significant drop in delivery volume, indicates a lack of investor confidence. Although institutional holdings are high at 28.94%, suggesting some level of confidence from larger investors, the overall market sentiment appears to be negative, further exacerbating the stock's decline.
