In the broader market context, the stock's short-term performance has been relatively better than the benchmark, as it has increased by 2.16% over the past week while the Sensex has declined by 1.05%. However, the overall trend remains concerning, with the stock underperforming against the benchmark over the last three years, generating returns of -55.65% compared to the Sensex's positive return of 37.31%. The company's consistent negative results and low ability to service debt contribute to a risky investment profile, which may be influencing investor sentiment and leading to the recent price decline.
