Why is Tata Motors falling/rising?

As of 08-Aug, Tata Motors Ltd. is experiencing a decline in its stock price, currently at Rs 633.30, which reflects a decrease of Rs 14.2 or 2.19%. The stock has been underperforming, having fallen consecutively for the last three days, resulting in a total decline of 3.25% during this period. Additionally, it is trading below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages. The stock's performance over the past week shows a decrease of 2.38%, and it has significantly underperformed the benchmark Sensex, which has only declined by 0.92%. The company's net sales and profits have also seen substantial declines, with net sales falling by 5.2% and profits after tax decreasing by 36.6% compared to previous quarters.
In the broader market context, Tata Motors' short-term performance is notably weaker than the benchmark, as it has underperformed the BSE500 over the last three years, one year, and three months. Despite a healthy long-term growth rate in net sales and a strong return on equity, the stock's recent performance has been hampered by falling investor participation and a significant drop in profits. The high institutional holdings at 34.42% indicate that these investors have the resources to analyze the company's fundamentals, yet the overall sentiment remains negative due to the stock's substantial decline of 39.18% over the past year.
