Why is Natl. Oxygen falling/rising?

As of 13-Aug, National Oxygen Ltd's stock price is currently at Rs 127.80, reflecting an increase of Rs 9.2 or 7.76%. Today's price summary indicates that the stock has outperformed its sector by 8.66%, marking a trend reversal after two consecutive days of decline. The stock opened with a gain of 2.87% and reached an intraday high of Rs 129.7, although it has shown a negative return of -6.17% over the past week and -2.48% over the past month. Despite this recent uptick, the company faces significant challenges, including a negative book value and weak long-term growth, with net sales declining at an annual rate of -1.04% over the last five years. The company has also reported negative results for the last three consecutive quarters, which has contributed to a perception of risk among investors.
In the broader market context, the Sensex has remained relatively flat with a change of -0.01% over the past week, while National Oxygen Ltd's stock has seen a more pronounced decline in the same period. This indicates that the stock's recent rise is somewhat isolated from the overall market trend, as it has not performed well year-to-date with a return of -4.52% compared to the Sensex's positive return of +3.07%. The stock's liquidity appears adequate for trading, but the company's weak fundamentals, including a poor EBIT to interest ratio and a significant drop in profits, suggest that the recent price increase may not be sustainable in the long term.
