Why is Sundaram Finance falling/rising?

As of 09-Jul, Sundaram Finance Ltd's stock price is currently at Rs 5,023.80, reflecting a decrease of Rs 144.7 or 2.8%. The stock has underperformed its sector by 3.18% today and has experienced a trend reversal, falling after four consecutive days of gains. It opened with a significant loss of 5.19% and reached an intraday low of Rs 4,900.05. Despite its strong long-term fundamentals, including a high Return on Equity (ROE) of 13.90% and positive quarterly results, the stock's recent performance has been impacted by a notable decline in investor participation, with delivery volume dropping by 61.46% compared to the five-day average. Over the past year, the stock has generated a return of 10.52%, outperforming the BSE500, but its recent short-term performance has been less favorable.
In the broader market context, the Sensex has shown a slight gain of 0.15% over the past week, contrasting with Sundaram Finance's decline of 1.02% during the same period. While the stock has performed well year-to-date with a return of 20.91%, its recent underperformance highlights a divergence from the overall market trend. The high institutional holdings at 26.54% suggest that more informed investors are backing the stock, but the current liquidity and trading volume issues may be contributing to the downward pressure on its price.
