Why is Sundaram Finance falling/rising?

As of 04-Sep, Sundaram Finance Ltd is currently priced at 4,507.20, reflecting an increase of 27.2 points or 0.61%. The stock has been gaining for the last two days, with a total return of 4.12% during this period. However, it is trading below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating a potential weakness in momentum. Additionally, there has been a significant decline in investor participation, with delivery volume dropping by 72.18% against the 5-day average. While the company boasts strong long-term fundamentals with an average Return on Equity (ROE) of 13.90% and high institutional holdings at 26.63%, it faces challenges due to flat results reported on June 25 and an expensive valuation with a Price to Book Value of 3.8, which may deter some investors.
In the broader market context, Sundaram Finance's short-term performance has been underwhelming compared to the benchmark Sensex, which has gained 0.80% over the past week while the stock has declined by 2.58%. Despite a year-to-date return of 8.48% compared to the Sensex's 3.30%, the stock's one-year performance shows a decline of 9.84%, contrasting with the benchmark's slight drop of 1.98%. This disparity in performance may reflect investor concerns regarding the company's recent operating cash flow results and overall valuation, which could be influencing the stock's current price movement.
