Why is Naapbooks falling/rising?

As of 25-Jul, Naapbooks Ltd's stock price is currently at 140.00, reflecting a decrease of 4.9, or 3.38%. Today's price summary indicates that the stock underperformed its sector by 1.91% and opened with a loss of 3.38%. It reached an intraday low of Rs 140 and has not shown any price range movement since opening. The stock has also experienced erratic trading, not trading on 4 out of the last 20 days, and there has been a significant decline in investor participation, with delivery volume dropping by 83.33% compared to the 5-day average. Over the past week, the stock has declined by 3.38%, while its year-to-date performance shows a loss of 6.67%, despite a remarkable 100% increase over the past year.
In the broader market context, Naapbooks' recent performance contrasts with the Sensex, which has only decreased by 0.36% over the past week. While Naapbooks has shown strong growth over the longer term, with a 660.29% increase over the past three years, its current decline indicates a short-term struggle. The stock's performance today, combined with the significant drop in trading volume and the lack of positive factors reported, suggests that investor sentiment may be waning, contributing to the stock's downward movement.
