Why is NCC Blue Water falling/rising?

As of 05-Jun, NCC Blue Water Products Ltd. is experiencing a price increase, currently at 16.88, reflecting a rise of 0.8 or 4.98%. The stock has shown strong performance recently, gaining 20.57% over the past week and outperforming its sector by 6.17% today. It has been on a consecutive gain streak for the last four days, and it is trading above all key moving averages, indicating positive momentum. However, there is a noted decline in investor participation, with delivery volume falling by 10.71% against the five-day average, which could suggest some caution among investors despite the stock's upward trajectory.
In the broader market context, while NCC Blue Water has outperformed the Sensex by a significant margin in the short term, with a weekly return of 20.57% compared to the Sensex's slight decline of 0.23%, its year-to-date performance shows a decline of 2.43%, contrasting with the Sensex's gain of 4.23%. This indicates that while the stock is currently rising, it has faced challenges earlier in the year. The overall market sentiment appears mixed, with the stock's recent gains not fully reflecting its longer-term performance relative to the benchmark.
