Why is Chola Financial falling/rising?

As of 09-Oct, Cholamandalam Financial Holdings Ltd is experiencing a decline in its stock price, currently at Rs 1,831.25, which reflects a decrease of Rs 19.35 or 1.05%. The stock has underperformed its sector by 1.65% today and has been on a downward trend for the past three days, accumulating a total decline of 3.01%. Additionally, the stock touched an intraday low of Rs 1,801.1, indicating a significant drop of 2.67%. Despite positive financial results over the last 11 quarters, including record net sales and cash equivalents, the stock has generated a negative return of 5.78% over the past year, although profits have increased by 13.1%. The stock is currently trading at a discount compared to its peers, with a price-to-book value of 2.7, and has high institutional holdings at 40.22%, which may provide some stability.
In the broader market context, Cholamandalam's short-term performance has been notably weaker compared to the benchmark Sensex, which has gained 1.47% over the past week while Cholamandalam has declined by 4.02%. This underperformance may be attributed to falling investor participation, as evidenced by a 61.94% drop in delivery volume compared to the five-day average. Although the stock remains liquid enough for trading, the recent trends indicate a lack of confidence among investors, contributing to its current price decline.
