Why is NIIT falling/rising?

As of 21-Aug, NIIT Ltd's stock price is currently at 114.15, reflecting an increase of 0.65 (0.57%). The stock has shown a positive trend recently, gaining 4.06% over the past week, which is a notable performance compared to the Sensex's increase of 1.74% during the same period. The stock has been gaining for four consecutive days, and there has been a rise in investor participation, with delivery volume increasing by 4.51% against the five-day average. However, despite this short-term positive movement, the company faces significant long-term challenges, including a poor growth rate in net sales and operating profit over the past five years, which has led to a negative EBITDA and a high PEG ratio of 11.4, indicating that the stock may be overvalued relative to its earnings growth.
In the broader market context, while NIIT's recent performance has been positive, it has underperformed significantly over longer periods, with a year-to-date return of -40.20% compared to the Sensex's gain of 4.94%. This stark contrast highlights the stock's struggles in the long term, as it has consistently generated negative returns over various time frames, including a -3.63% return over the past year. The high institutional holdings at 23.49% suggest that more knowledgeable investors are involved, but the overall negative financial indicators and poor growth prospects may overshadow the recent gains, leading to a cautious outlook for the stock moving forward.
