Why is Natl. Oxygen falling/rising?

As of 04-Aug, National Oxygen Ltd's stock price is currently at Rs 140.00, reflecting an increase of Rs 7.9, or 5.98%. The stock has shown a strong performance today, outperforming its sector by 5.52% and reaching an intraday high of Rs 140. However, it also experienced a low of Rs 127.15 earlier in the day. Over the past week, the stock has gained 1.60%, and over the past month, it has risen by 8.74%, contrasting with a decline in the Sensex by 2.89%. Despite this positive short-term performance, the company faces significant challenges, including 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. Additionally, the company's ability to service its debt is compromised, evidenced by a poor EBIT to Interest ratio of 0.95.
In the broader market context, while National Oxygen has outperformed the Sensex in the short term, the benchmark has shown a decline over the past month, indicating a challenging market environment. The stock's performance is noteworthy given the broader market's struggles, as evidenced by its year-to-date return of 4.59% compared to the Sensex's 3.69%. However, the stock's recent rise is tempered by falling investor participation, with delivery volume dropping significantly, suggesting potential concerns among investors regarding the company's long-term viability. Overall, while the stock is currently rising, its underlying fundamentals present a risky outlook, which may affect future performance.
