Why is NMS Global falling/rising?

As of 16-Jun, NMS Global Ltd's stock price is currently at Rs 44.73, reflecting an increase of Rs 1.58 or 3.66%. The stock has been gaining for the last two days, with a total return of 4% during this period. It opened with a gain of 3.66% today and reached an intraday high of Rs 44.73. However, the stock has shown a decline of 18.67% year-to-date and 15.62% over the past year, despite a strong performance in the last week and month, where it outperformed the Sensex by 13.96% and 17.74%, respectively. Notably, there has been a decrease in investor participation, with delivery volume falling by 33.04% against the 5-day average, which may indicate a lack of sustained buying interest.
In the broader market context, while NMS Global has outperformed the Sensex in the short term, the benchmark index has shown a positive return of 4.68% year-to-date, contrasting with the stock's significant decline. This suggests that despite recent gains, the stock's overall performance remains weak compared to the market. The liquidity of the stock appears adequate for trading, but the falling delivery volume could signal caution among investors. Overall, the recent price increase may be attributed to short-term trading activity rather than a fundamental shift in investor sentiment.
