Although there has been a notable increase in investor participation, with delivery volume rising by 173.15% against the 5-day average, the overall performance remains weak, as indicated by the stock's year-to-date return of -37.96% compared to the Sensex's gain of 4.85%.
In the broader market context, Supertex's recent performance starkly contrasts with the benchmark Sensex, which has shown a positive return of 2.07% over the past week. This underperformance highlights the challenges faced by Supertex, as it has not only lagged behind the benchmark but also recorded negative returns over multiple periods, including a 10.05% decline over the past month. The lack of available positive factors further emphasizes the difficulties the company is encountering, contributing to the downward pressure on its stock price.
