In the broader market context, while Envirotech's short-term performance has been strong, the overall market, as represented by the Sensex, has shown mixed results, with a slight gain of 3.42% over the past month. Despite the stock's impressive returns, the decline in delivery volume could indicate a potential slowdown in buying interest, which may affect future price movements.
