Why is CRISIL falling/rising?

As of 24-Oct, CRISIL Ltd. is experiencing a slight increase in its stock price, currently at 4,964.30, with a change of 10.1, representing a 0.2% rise. The stock has outperformed its sector today by 0.36%, and its delivery volume has seen a significant increase of 107.52% compared to the 5-day average, indicating rising investor participation. Over the past week, CRISIL has shown a return of +5.31%, which is substantially higher than the Sensex's +0.31%. However, despite these positive short-term movements, the stock has a year-to-date decline of -25.73% and a one-year return of -2.23%, reflecting challenges in long-term growth, as evidenced by a modest annual growth rate in net sales and operating profit over the last five years.
In the broader market context, CRISIL's recent performance contrasts with the benchmark Sensex, which has gained +7.77% year-to-date. While the stock's short-term returns are favorable, the long-term outlook remains concerning due to its high valuation metrics, including a Price to Book Value of 14.2 and a PEG ratio of 4.1, suggesting it may be overvalued relative to its earnings growth. Additionally, despite a high return on equity (ROE) of 29.95% and low debt levels, the company's flat results in September and the overall negative performance over the past year indicate that investors may be cautious about its future growth potential.
