Why is NIIT Learning falling/rising?

As of 16-Sep, NIIT Learning Systems Ltd is experiencing a price increase, currently at 335.45, reflecting a rise of 3.6 or 1.08%. The stock has been gaining for the last two days, with a total return of 1.21% during this period. It has outperformed its sector by 0.76% today, and the delivery volume has increased by 19.38% compared to the five-day average, indicating rising investor participation. Despite a year-to-date decline of 25.21% and a one-year drop of 33.58%, the company maintains a high return on equity (ROE) of 20.84% and a low debt-to-equity ratio, which contributes to its attractive valuation. High institutional holdings at 39.65% suggest confidence from more knowledgeable investors, which may positively influence retail investor sentiment.
In the broader market context, the stock's short-term performance over the past week shows a return of 1.04%, which is lower than the Sensex's gain of 1.58%. However, the stock has outperformed the benchmark over the past month, with a return of 2.44% compared to the Sensex's 2.21%. This indicates that while the stock is currently rising, it has underperformed significantly over the longer term, particularly in the year-to-date and one-year comparisons against the benchmark. The overall market sentiment appears to be cautiously optimistic, as indicated by the stock's recent performance and the positive factors surrounding its management efficiency and valuation.
