Why is Natl. Oxygen falling/rising?

As of 19-Aug, National Oxygen Ltd's stock is currently priced at 124.25, reflecting an increase of 2.25, or 1.84%. Today's price movement indicates a trend reversal, as the stock has gained after two consecutive days of decline. Despite this uptick, the stock has shown a significant decline of 11.38% over the past month and a year-to-date decrease of 7.17%. The stock's performance today is in line with its sector, but it has experienced a notable drop in investor participation, with delivery volume falling by 65.89% compared to the five-day average. Additionally, the company has a negative book value and has reported negative results for the last three consecutive quarters, which raises concerns about its long-term fundamental strength and ability to service debt.
In the broader market context, the stock's short-term return of +4.76% over the past week outperforms the benchmark Sensex, which has increased by only 1.76% during the same period. However, the stock has consistently underperformed against the benchmark over the last three years, with a return of -23.35% compared to the Sensex's +36.88%. This underperformance, coupled with poor long-term growth and negative EBITDA, suggests that while there may be short-term gains, the overall outlook for National Oxygen Ltd remains weak, contributing to the stock's volatility and investor caution.
