The company also boasts strong fundamentals, with a high Return on Equity (ROE) of 13.90%, and has reported its highest quarterly PAT and net sales recently, which contributes positively to investor sentiment.
In the broader market context, Sundaram Finance's short-term return of 0.36% over the past week is notably higher than the Sensex's minimal increase of 0.02%, indicating that the stock is performing well relative to the market. However, it is important to note that there has been a significant decline in investor participation, with delivery volume falling by 86.96% compared to the 5-day average, which may raise concerns about liquidity and future trading activity. Despite this drop in participation, the stock remains liquid enough for trading, suggesting that institutional investors, who hold 26.54% of the stock, continue to support it due to their capability to analyze the company's fundamentals effectively.
