Why is Grindwell Norton falling/rising?

As of 06-Nov, Grindwell Norton Ltd. is experiencing a decline in its stock price, currently at Rs 1,593.55, which reflects a decrease of Rs 58.4 or 3.54%. The stock has been underperforming, having fallen consecutively for the last three days, resulting in a total decline of 5.44% during this period. Today's performance indicates that it has underperformed its sector by 1.29%, with an intraday low of Rs 1,580.25. The stock is trading below all its moving averages, and there has been a significant drop in investor participation, as evidenced by a 64.64% decrease in delivery volume compared to the five-day average. Additionally, the stock has shown poor long-term growth, with net sales increasing at an annual rate of only 14.83% over the last five years, and a low debt-to-equity ratio, which, while positive, does not offset the concerns regarding its valuation and performance.
In the broader market context, Grindwell Norton has underperformed against the benchmark, with a one-week return of -5.06% compared to the Sensex's -1.30%. Over the past year, the stock has generated a return of -28.08%, significantly lagging behind the Sensex, which has increased by 3.65%. This consistent underperformance over multiple periods, coupled with a high PEG ratio of 27.5 and a very expensive valuation relative to its fundamentals, suggests that investor sentiment is negative. The combination of these factors indicates that the stock's recent decline is influenced by both its internal financial performance and its inability to keep pace with broader market trends.
