Why is NRB Indl Bearing falling/rising?

As of 08-Aug, NRB Industrial Bearings Ltd is experiencing a price increase, currently at Rs 23.87, which reflects a rise of 1.13 or 4.97%. The stock has shown a positive performance today, outperforming its sector by 6.91% and has gained consecutively over the last two days, accumulating a total return of 10.2%. Despite this recent uptick, the stock has had a challenging month, with a decline of 13.20% over the past month and a significant drop of 41.51% over the past year. The stock opened with a gain today and has maintained this price, although it is trading higher than its 5-day moving averages but lower than its longer-term moving averages. Notably, there has been a substantial decline in investor participation, with delivery volume falling by 85.46% compared to the 5-day average, indicating a potential concern for liquidity.
In the broader market context, the stock's short-term performance has been notably better than the benchmark, with a 1-week return of +7.18% compared to the Sensex's -0.92%. This suggests that while NRB Industrial Bearings Ltd is currently gaining traction, the overall market sentiment may not be as favorable, particularly given the sector's decline of 2%. The stock's year-to-date performance is slightly positive at +0.29%, contrasting with the Sensex's +2.20%, indicating that while the stock is currently rising, it has faced significant volatility and challenges over the longer term.
