Why is Arihant Academy falling/rising?

As of 29-Oct, Arihant Academy Ltd's stock price is currently at 465.00, reflecting a decrease of 21.4 points or 4.4%. Today's price summary indicates that the stock has underperformed its sector by 4.41%. While the stock is trading higher than its 50-day, 100-day, and 200-day moving averages, it is lower than its 5-day and 20-day moving averages. The stock has seen a significant increase in investor participation, with delivery volume rising by 150% against the 5-day average. Despite a strong year-to-date return of 85.41% and a remarkable 119.39% increase over the past year, the stock's recent decline may be attributed to its very expensive valuation, as indicated by a high Price to Book Value ratio of 11.2, despite a solid management efficiency reflected in a high ROE of 19.01% and low debt levels.
In the broader market context, the stock's performance over the past week shows a decline of 9.18%, contrasting with the Sensex, which has gained 0.72% during the same period. This underperformance in the short term suggests that while Arihant Academy has delivered impressive long-term growth, recent price movements may be influenced by market sentiment regarding its valuation and profitability metrics. The stock's high PEG ratio of 0.3, despite strong profit growth, indicates that investors may be reassessing their expectations, leading to the current price decline.
