Why is Panasonic Carbon falling/rising?

As of 08-Jul, Panasonic Carbon India Company Ltd. is experiencing a decline in its stock price, currently at 518.95, which reflects a decrease of 3.05 or 0.58%. The stock has been underperforming, having fallen consecutively for the last five days, resulting in a total decline of 2% during this period. Additionally, the stock has underperformed its sector by 0.9% today. Over the past week, the stock has decreased by 2.00%, and over the past month, it has seen a significant drop of 9.92%. Despite a relatively low Debt to Equity ratio and rising investor participation, indicated by a 25.02% increase in delivery volume, the company faces challenges such as poor long-term growth, with net sales growing at an annual rate of only 3.71% over the last five years.
In the broader market context, the Sensex has shown a slight increase of 0.02% over the past week, contrasting with Panasonic Carbon's decline. While the stock has generated a modest return of 1.75% over the past year, it has underperformed the benchmark significantly, which has risen by 4.69% in the same period. The company's recent financial results have been disappointing, with net sales falling by 5.7% in the latest quarter and a low operating profit. This combination of flat results and an expensive valuation, alongside a PEG ratio of 1, suggests that the stock may be perceived as overvalued, contributing to its recent price decline.
