Why is Star Cement falling/rising?

As of 12-Sep, Star Cement Ltd. is currently priced at 272.40, reflecting a slight increase of 0.65, or 0.24%. The stock has shown a trend reversal, gaining after six consecutive days of decline. Despite this recent uptick, the stock has underperformed in the short term, with a 1-week return of -7.11% compared to the Sensex's gain of +1.48%. Additionally, the stock's delivery volume has decreased significantly, falling by 34.39% against the 5-day average, indicating reduced investor participation. However, the company maintains a low debt-to-equity ratio of 0.03 times, which is a positive factor, and it has outperformed the BSE500 over various time frames, including a 30.30% return over the past year.
In the broader market context, Star Cement's recent performance contrasts sharply with the benchmark, as it has experienced a decline while the Sensex has shown positive movement. The stock's year-to-date return of +17.52% and a remarkable +171.86% over three years demonstrate strong long-term performance, yet the recent short-term struggles highlight a disconnect with broader market trends. The liquidity of the stock remains adequate for trading, but the falling investor participation suggests caution among traders, which could be influencing the stock's recent price movements.
