Why is Sundaram Fin.Hol falling/rising?

As of 10-Jul, Sundaram Finance Holdings Ltd is experiencing a price increase, currently at 492.65, reflecting a rise of 4.75 or 0.97%. Today's price summary indicates that the stock has outperformed its sector by 0.84%. Despite a recent decline in investor participation, with a 34.86% drop in delivery volume compared to the 5-day average, the stock remains liquid enough for trading. Over the past month, the stock has shown a significant increase of 19.62%, and it has delivered an impressive year-to-date return of 64.57%. However, it is important to note that the company has faced challenges, including a substantial fall in earnings per share and negative sales growth, which could impact investor sentiment.
In the broader market context, the stock's short-term performance has been slightly negative, with a 1-week return of -0.55%, while the benchmark Sensex has declined by only 0.20% during the same period. This indicates that while the stock has shown strong long-term growth with an annual operating profit growth rate of 27.53%, it is currently facing headwinds that may affect its short-term performance. Despite these challenges, the stock has consistently outperformed the BSE500 over the last three years, generating returns of 82.46% in the past year, which suggests a strong underlying fundamental strength that may support its price movement.
