Why is Century Extrus. falling/rising?

As of 09-Jul, Century Extrusions Ltd is experiencing a price increase, currently at 22.22, reflecting a rise of 0.43 or 1.97%. Today's price summary indicates that the stock has outperformed its sector by 3.7% and has shown a trend reversal after five consecutive days of decline. Despite this positive movement, the stock has a one-week return of -6.95% and a year-to-date return of -9.05%, indicating a challenging performance over these periods. However, the company has reported strong financial metrics, including a high return on capital employed (ROCE) of 16.78% and significant increases in net sales and profit after tax in the latest quarter, which may contribute to the stock's recent upward movement.
In the broader market context, the Sensex has shown a slight increase of 0.15% over the past week, contrasting with Century Extrusions' short-term decline. While the stock has underperformed the benchmark in the short term, its long-term performance over three years is impressive, with a return of 123.99% compared to the Sensex's 53.33%. The stock's attractive valuation, trading at a discount to peers and a favorable PEG ratio of 0.5, suggests that it may be undervalued despite recent volatility, potentially attracting investor interest and supporting the recent price rise.
