Why is NRB Indl Bearing falling/rising?

As of 18-Sep, NRB Industrial Bearings Ltd is experiencing a decline in its stock price, currently at Rs 31.81, which reflects a decrease of Rs 1.05 or 3.2%. The stock has underperformed its sector by 3.26% today and has been on a downward trend for the last two days, resulting in a total drop of 5.04%. Despite a strong performance over the past month and year-to-date, with returns of 18.65% and 33.66% respectively, the stock's recent movement is influenced by a significant drop in delivery volume, which has decreased by 64.46% compared to the five-day average. Additionally, the company has a negative book value and weak long-term fundamentals, as evidenced by stagnant operating profit and high debt levels, which contribute to the stock's riskiness.
Broader market context indicates that while NRB Industrial Bearings has shown positive short-term returns, it has consistently underperformed against the benchmark BSE500 over the last three years, including a negative return of 13.35% in the past year. The Sensex has only marginally increased by 0.08% during the same period, highlighting the stock's relative weakness. The overall market sentiment may be affected by the company's poor long-term growth prospects and negative EBITDA, which could lead investors to be cautious, further contributing to the stock's decline.
