Why is Sundaram Finance falling/rising?

As of 05-Sep, Sundaram Finance Ltd's stock price is currently at 4,523.00, reflecting an increase of 15.8 points or 0.35%. The stock has been gaining for the last three days, with a total return of 4.49% during this period. However, it is important to note that the stock's performance over the past month shows a decline of 2.58%, while year-to-date, it has risen by 8.86%. The stock's delivery volume has decreased significantly, falling by 40.75% against the five-day average, indicating a drop in investor participation. Despite this, the company boasts strong long-term fundamentals with an average Return on Equity (ROE) of 13.90% and high institutional holdings at 26.63%, which may provide some support for the stock's price.
In the broader market context, the stock's short-term performance of +0.61% over the past week is lagging behind the Sensex, which has gained 1.13% during the same period. While the stock has shown resilience with a significant increase over three years (+107.78%), it has underperformed over the past year with a decline of 8.40%. The recent flat operating cash flow results and high valuation metrics, such as a Price to Book Value of 3.8, suggest that the stock may be trading at a premium compared to its peers, which could deter some investors. Overall, while there are positive long-term fundamentals, the recent decline in investor participation and mixed short-term performance relative to the benchmark may contribute to a cautious outlook for Sundaram Finance Ltd.
