Why is C D S L falling/rising?

As of 31-Jul, Central Depository Services (India) Ltd is experiencing a decline in its stock price, currently at 1,480.80, reflecting a decrease of 32.0 points or 2.12%. The stock has underperformed its sector by 1.83% today, and its delivery volume has fallen by 7.57% against the 5-day average, indicating a decrease in investor participation. Over the past week, the stock has dropped by 11.82%, and it has also seen a significant decline of 17.62% over the past month, contrasting with its positive performance over the last year, where it generated an 18.39% return. Despite strong long-term fundamentals, including a robust average Return on Equity (ROE) of 26.52% and healthy growth in net sales and operating profit, the recent price movement suggests a short-term struggle.
In the broader market context, the stock's recent performance has been notably weaker than the benchmark, with the Sensex declining only 1.17% over the past week. This underperformance is further highlighted by the stock's negative returns in the short term compared to the benchmark's relatively stable performance. While the company has high institutional holdings at 27.13%, which typically indicates confidence from more knowledgeable investors, the current market sentiment appears to be weighing heavily on the stock's price, leading to its recent decline.
