Why is Sundaram Finance falling/rising?

As of 04-Aug, Sundaram Finance Ltd is experiencing a decline in its stock price, currently at Rs 4,462.00, reflecting a decrease of Rs 106.5 or 2.33%. The stock has underperformed its sector by 3.95% today and has been on a downward trend for the last three days, accumulating a total loss of 6.5% during this period. Additionally, the stock is trading below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating a bearish trend. Despite a strong long-term fundamental strength with an average Return on Equity (ROE) of 13.90% and high institutional holdings at 26.63%, the stock's recent performance has been negatively impacted by flat results in June and an operating cash flow that is the lowest at Rs -8,985.25 Cr. The stock's valuation appears expensive 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 notably weaker compared to the benchmark Sensex, which has seen a slight increase of 0.16% over the past week while the stock has dropped by 8.19%. Although the stock has shown positive returns year-to-date at 7.39%, the recent declines and underperformance against the benchmark suggest a lack of investor confidence in the short term. The stock's consistent returns over the last three years and its ability to outperform the BSE500 annually may not be sufficient to counteract the current negative sentiment driven by recent financial results and valuation concerns.
