Why is Hero MotoCorp falling/rising?

As of 24-Sep, Hero MotoCorp Ltd. is experiencing a decline in its stock price, currently at 5,277.55, which reflects a decrease of 91.85 points or 1.71%. The stock has underperformed its sector by 0.56% today and has been on a consecutive downward trend for the last two days, resulting in a total decline of 2.73%. In the past week, the stock has decreased by 1.35%, while over the past month, it has shown a positive return of 5.60%. Despite a healthy long-term growth trajectory, indicated by a 10.96% annual increase in net sales and a low debt-to-equity ratio, the stock's recent performance has been impacted by falling investor participation, with delivery volume dropping by 38.28% against the five-day average.
In the broader market context, the stock's short-term performance has been slightly worse than the benchmark Sensex, which has declined by 1.18% over the same period. However, Hero MotoCorp has outperformed the Sensex year-to-date with a return of 26.81% compared to the benchmark's 4.58%. The company benefits from high institutional holdings at 54.88%, which suggests strong confidence among informed investors. Despite the recent price drop, the stock is still considered a strong buy due to its attractive valuation metrics, including a PEG ratio of 0.9 and a high return on capital employed, which indicates robust profitability.
