Why is HCL Infosystems falling/rising?

As of 21-Aug, HCL Infosystems Ltd's stock price is currently at 15.20, reflecting an increase of 0.68 or 4.68%. The stock has shown a positive performance today, outperforming its sector by 4.87% and has been on a consecutive gain streak for the last three days, accumulating a total return of 5.78% during this period. However, despite this recent uptick, the stock has experienced a decline of 5.59% over the past month and a significant drop of 9.52% over the last year. The company faces challenges such as a negative book value and weak long-term fundamental strength, evidenced by a -55.23% annual growth rate in net sales over the past five years and a high debt to EBITDA ratio of -1.00 times, which may contribute to investor caution despite the recent price increase.
In the broader market context, HCL Infosystems' short-term return of +5.26% over the past week significantly outpaces the Sensex's return of +1.74% during the same period. However, the stock has consistently underperformed against the benchmark over the last three years, with a total return of -11.11% compared to the Sensex's +37.48%. This underperformance, combined with the company's flat results and negative EBITDA, indicates a risky investment profile, which may temper enthusiasm despite the recent gains.
