Why is Unitech Internat falling/rising?

As of 02-Sep, Unitech International Ltd's stock price is currently at 4.72, reflecting an increase of 0.15 or 3.28%. The stock has shown a positive trend recently, gaining for the last three days with a total return of 4.89% during this period. However, despite this short-term gain, the company has a negative book value and a high Debt to EBITDA ratio of 7.51 times, indicating a weak long-term fundamental strength. The stock has consistently underperformed against the benchmark over the last three years, generating a return of -26.13% in the past year, which raises concerns for investors regarding its ability to service debt and sustain operations without raising fresh capital or reporting profits.
In the broader market context, Unitech's short-term performance has outpaced the Sensex, which has declined by 0.78% over the past week while Unitech has increased by 2.39%. Despite this outperformance, the stock's liquidity is noted to be adequate, but there is a concerning trend of falling investor participation, with delivery volume decreasing by 34.25% against the five-day average. This combination of short-term gains against a backdrop of long-term underperformance and negative financial indicators suggests that while the stock may be rising in the short term, significant risks remain for potential investors.
