Why is ACC falling/rising?

As of 14-Aug, ACC Ltd's stock price is currently at 1,782.90, reflecting a decrease of 5.65, or 0.32%. The stock has been trading close to its 52-week low, just 0.44% away from Rs 1,775.05, and has shown a trend reversal after two consecutive days of gains. It has been underperforming, with a 1-week return of -1.77% and a 1-month return of -9.67%, while also trading below its moving averages across various time frames. Additionally, there has been a significant drop in investor participation, with delivery volume falling by 38.25% against the 5-day average. Despite a low debt-to-equity ratio and attractive valuation metrics, the stock's recent performance has been hindered by flat quarterly results and consistent underperformance against benchmarks over the past three years.
In the broader market context, ACC's recent performance contrasts sharply with the Sensex, which has seen a minimal decline of only 0.03% over the same week. The stock's year-to-date performance is particularly concerning, with a decline of 13.18% compared to the Sensex's gain of 3.15%. This underperformance is compounded by the company's reported flat results in June, which saw a significant drop in profit after tax compared to previous quarters. While high institutional holdings may provide some stability, the overall trend indicates a lack of confidence among investors, contributing to the stock's downward movement.
