Over the past year, the stock has generated negative returns of 16.35%, contrasting sharply with the Sensex's positive return of 6.64%. This underperformance highlights the stock's struggles in the market, particularly given its high debt levels and negative EBITDA, which make it a risky investment compared to its historical valuations.
