Why is Carborundum Uni. falling/rising?

As of 19-Aug, Carborundum Universal Ltd's stock is currently priced at 871.00, reflecting a decrease of 8.4 points or 0.96%. The stock has underperformed its sector by 0.9% today, despite a notable increase in delivery volume, which rose by 108.15% against the 5-day average. Over the past week, the stock has shown a positive return of 2.71%, but it has significantly underperformed over the longer term, with a decline of 11.66% over the past month and a staggering 44.34% drop over the past year. The company has reported negative results for the last two consecutive quarters, with a 15.43% fall in net profit and a low return on capital employed (ROCE) of 15.65%, contributing to a perception of poor long-term growth.
In the broader market context, while the Sensex has gained 1.76% over the past week, Carborundum Universal Ltd's performance has lagged behind, indicating a lack of investor confidence. The company's promoters have reduced their stake by 0.59%, which may signal diminished confidence in the company's future prospects. Additionally, the stock's valuation appears expensive with a price-to-book ratio of 4.7, and despite trading at a discount compared to its peers, the overall negative sentiment surrounding its declining profits and poor operational metrics has led to a bearish outlook.
