Why is Kajaria Ceramics falling/rising?

As of 17-Sep, Kajaria Ceramics Ltd. is currently priced at 1,235.00, reflecting a slight increase of 0.65 (0.05%). The stock has been gaining over the last two days, with a total return of 1.13% during this period. However, it has underperformed its sector by 0.5% today. The stock's performance over the past week and month shows declines of 0.68% and 2.49%, respectively, while it has a year-to-date return of 6.51%. Despite its high management efficiency indicated by a return on equity of 15.46% and a low debt-to-equity ratio, the stock has seen a decrease in investor participation, with delivery volume falling by 31.53% against the five-day average.
Broader market context indicates that while Kajaria Ceramics has experienced a year-to-date gain, it has underperformed compared to the Sensex, which has risen by 5.83% in the same period. The stock's recent performance contrasts with the benchmark's 1.56% gain over the past week. This underperformance, coupled with declining investor participation and a higher concentration of institutional holdings, suggests that while the company remains a significant player in its sector, it faces challenges in attracting retail investor interest in the short term.
