Why is Cello World falling/rising?

As of 20-Aug, Cello World Ltd's stock price is currently at Rs 549.80, reflecting an increase of Rs 10.9 or 2.02%. The stock has been gaining for the last two days, with a total return of 3.54% during this period. It reached an intraday high of Rs 562.85, which is a rise of 4.44%. Despite this recent uptick, the stock has experienced a significant decline over the past month, down 11.39%, and a staggering 39.86% over the past year. The company exhibits high management efficiency with a return on equity (ROE) of 15.63% and a low debt-to-equity ratio, which are positive indicators. However, the stock faces challenges due to poor long-term growth, as evidenced by flat operating profit results and a high price-to-book value ratio, suggesting it may be overvalued.
In the broader market context, Cello World Ltd's recent performance is somewhat in line with the FMCG sector, which has gained by 2.19%. However, the stock's short-term return of 3.54% over the last two days is less than the Sensex's 1-week return of 1.03% and significantly lower than the benchmark's performance over the past month, where the Sensex has increased by 1.64%. This indicates that while the stock is experiencing a short-term rise, it still lags behind the broader market trends, particularly in the long term, where it has underperformed relative to the BSE500 index.
