Why is Panasonic Carbon falling/rising?

As of 12-Sep, Panasonic Carbon India Company Ltd. is experiencing a decline in its stock price, currently at 485.00, reflecting a decrease of 7.2 points or 1.46%. The stock has underperformed its sector by 2.57% today and has been on a downward trend for the last two days, with a total decline of 1.55% during this period. Over the past week, the stock has shown a negative return of 2.20%, and its performance over the last year has been particularly poor, with a drop of 27.23%. The company has a low Debt to Equity ratio, which is a positive factor; however, its long-term growth prospects are concerning, with net sales and operating profit growing at rates of only 5.58% and 4.48%, respectively, over the last five years. Additionally, the stock's valuation appears expensive with a Price to Book Value of 1.4, and it has underperformed against the BSE500 index in both the short and long term.
In the broader market context, the Sensex has shown a positive return of 1.48% over the past week, contrasting sharply with Panasonic Carbon's decline. While the stock's liquidity appears sufficient for trading, the overall market sentiment seems to favor other investments, as evidenced by the stock's significant underperformance compared to the benchmark indices. The company's flat results in June and reliance on non-operating income further contribute to the negative outlook, leading to a lack of investor confidence and a continued decline in stock price.
