Why is Volt.Transform. falling/rising?

As of 03-Sep, Voltamp Transformers Ltd's stock price is currently at 8,115.00, reflecting an increase of 85.0, or 1.06%. The stock has shown a positive trend recently, gaining 3.75% over the last three days and outperforming its sector by 0.36%. However, despite this short-term gain, the stock has experienced a decline of 4.85% over the past month and a significant drop of 20.10% year-to-date. The company benefits from strong long-term fundamentals, including a healthy operating profit growth rate of 34.07%, a low debt-to-equity ratio, and a solid return on equity of 17.76%. Additionally, high institutional holdings at 46.71% suggest confidence from more knowledgeable investors, which may support the stock's recent upward movement.
In the broader market context, the stock's recent performance contrasts with the Sensex, which has seen a slight decline of 0.27% over the past week. While Voltamp Transformers Ltd has outperformed the benchmark in the short term, its longer-term performance remains concerning, with a 41.62% drop over the past year compared to the Sensex's decline of only 2.41%. The stock's liquidity is adequate, but a notable decrease in delivery volume by 34.67% against the five-day average indicates a potential decline in investor interest, which could affect future price movements.
