Why is NIIT Learning falling/rising?

As of 15-Sep, NIIT Learning Systems Ltd is experiencing a slight increase in its stock price, currently at Rs 331.85, reflecting a change of 0.4 (0.12%) upwards. Today's performance indicates a trend reversal as the stock has gained after two consecutive days of decline, outperforming its sector by 1.98%. Despite this positive movement, the stock has underperformed in the short term, with a 1-week return of -0.18% compared to the Sensex's +1.24%. Over the past year, the stock has seen a significant decline of -34.42%, although its profits have increased by 1.8%. The company maintains a high management efficiency with a return on equity (ROE) of 20.84% and a low debt-to-equity ratio, which contributes to its attractive valuation.
In the broader market context, the stock's recent performance contrasts with the benchmark, as it has lagged behind the Sensex, which has gained +1.24% over the past week and +4.67% year-to-date. While the stock's liquidity remains adequate for trading, there has been a notable decrease in investor participation, with delivery volume falling by 23.83% against the 5-day average. High institutional holdings at 39.65% suggest that informed investors are backing the company, which may provide some stability despite the stock's overall negative returns in the longer term.
