Why is NIIT Learning falling/rising?

As of 18-Aug, NIIT Learning Systems Ltd is experiencing a decline in its stock price, currently at Rs 322.90, which reflects a decrease of Rs 5.6 or 1.7%. The stock has underperformed its sector by 2.21% today and has been on a downward trend for the last two days, accumulating a total return loss of 1.81%. Over the past week, the stock has shown a modest increase of 0.70%, but it has significantly underperformed over the longer term, with a year-to-date decline of 28.00% compared to a 4.01% gain in the benchmark Sensex. Despite a high management efficiency indicated by a return on equity (ROE) of 20.84% and a low debt-to-equity ratio, the stock's recent performance has been negatively impacted by its trading below all major moving averages and a substantial year-over-year return loss of 30.53%.
In the broader market context, the stock's short-term performance has lagged behind the Sensex, which has gained 0.83% over the past week. While the stock has seen a rise in investor participation, with a notable increase in delivery volume, the overall sentiment remains cautious due to its significant underperformance over the past year. The high institutional holdings at 39.65% suggest that knowledgeable investors are backing the company, but this has not translated into positive price movement recently. The stock's attractive valuation relative to peers, indicated by a price-to-book value of 3.7, may not be sufficient to counteract the prevailing negative trends influencing its price.
