Why is Tata Motors PVeh falling/rising?

As of 28-Oct, Tata Motors Passenger Vehicles Ltd is experiencing a price increase, currently at 411.60, reflecting a rise of 1.5 (0.37%). The stock has shown a positive performance today, outperforming its sector by 0.9%, and has gained consecutively over the last two days, with a total return of 2.01% in this period. Despite a decline of 1.04% over the past month and a significant drop of 24.20% over the past year, the stock has demonstrated healthy long-term growth with net sales increasing at an annual rate of 13.59%. However, it has faced challenges, including a 39.8% fall in profits over the past year, which has contributed to its underperformance compared to the broader market.
In the broader market context, Tata Motors has outperformed the Sensex in the short term, with a 1-week return of 2.41% compared to the Sensex's 0.24%. Despite this recent uptick, the stock has significantly lagged behind the market over the past year, where the BSE500 has generated a return of 4.71%. The stock's high institutional holdings at 34.47% suggest that these investors have confidence in the company's fundamentals, yet the recent declines in profit before tax and net sales indicate underlying weaknesses that could affect future performance.
