Why is Sharda Motor falling/rising?

As of 12-Nov, Sharda Motor Industries Ltd is experiencing a decline in its stock price, currently at 1,049.80, which represents a decrease of 124.55 or 10.61%. Today's performance indicates that the stock has underperformed its sector by 11.46%, opening with a significant loss of 8.89% and reaching an intraday low of Rs 1,018.85, reflecting a drop of 13.24%. Over the past week, the stock has decreased by 3.05%, while its year-to-date performance remains positive at 13.19%. Despite the long-term fundamentals showing strong growth with an average return on equity of 25.69% and a healthy increase in net sales, the stock's recent movement has been negatively impacted by a decline in profits and a high PEG ratio of 7.3, suggesting that the stock may be overvalued compared to its earnings growth.
In the broader market context, the Sensex has increased by 1.21% over the past week, contrasting with Sharda Motor's decline, indicating that the stock is not only underperforming its sector but also lagging behind the overall market. This divergence may reflect investor sentiment shifting away from the stock, particularly after two consecutive days of gains were reversed. The rising investor participation, with a delivery volume increase of 59.75% against the 5-day average, suggests some interest in the stock, but the overall liquidity and trading patterns indicate caution among investors.
