Why is Cella Space falling/rising?

As of 27-Jun, Cella Space Ltd. is experiencing a slight increase in its stock price, currently at 14.86, with a change of 0.02 (0.13%) upwards. The stock has shown strong performance over the past week, gaining 14.22%, and has outperformed the benchmark Sensex, which rose by 2.00%. Additionally, Cella Space has been gaining for the last two days, with a total return of 4.13% during this period. Despite this positive movement, the stock underperformed its sector by 0.38% today. The company has a negative book value and a weak long-term fundamental strength, with declining net sales and operating profit over the last five years, which poses risks to its future performance.
In the broader market context, while Cella Space has shown impressive returns over the past year, generating 21.90% compared to the Sensex's 6.08%, its long-term growth prospects appear limited due to high debt and poor sales growth. The stock's liquidity is adequate, with a significant increase in delivery volume, suggesting rising investor participation. However, the company's negative book value and high debt levels indicate that it is trading at a risky valuation compared to historical averages, which could affect investor sentiment moving forward.
