Why is Natl. Oxygen falling/rising?

As of 01-Aug, National Oxygen Ltd's stock price is flat at 132.10, showing no change (0.00%). The stock has underperformed in the short term, with a 1-week return of -2.87%, while it has performed better over the past month with a return of +6.70%. However, the stock's delivery volume has significantly decreased, falling by 99.13% against the 5-day average, indicating a decline in investor participation. Additionally, the company faces challenges such as a negative book value and weak long-term growth, with net sales declining at an annual rate of -1.57% over the last five years. The recent negative financial results, including the lowest net sales and operating profit margins, further contribute to a perception of risk surrounding the stock.
In the broader market context, the Sensex has shown a decline of -1.06% over the past week, which is less severe than National Oxygen's short-term performance. While the stock has outperformed its sector by 1.27% today, its year-to-date performance remains negative at -1.31%, contrasting with the Sensex's positive return of +3.15%. This suggests that despite some short-term resilience, the overall market conditions and the company's fundamental weaknesses are exerting downward pressure on the stock price.
