Why is Aegis Vopak Term falling/rising?

As of 22-Jul, Aegis Vopak Terminals Ltd is experiencing a decline in its stock price, currently at Rs 284.35, which reflects a decrease of Rs 7.75 or 2.65%. The stock has underperformed its sector by 0.61% today, having touched an intraday low of Rs 275, representing a drop of 5.85%. Despite this, the stock has shown positive performance over the past week and month, with returns of 6.46% and 15.97%, respectively. However, there has been a significant drop in investor participation, with delivery volume falling by 77.97% against the 5-day average, indicating reduced interest from investors. Unfortunately, there is no information available regarding positive or negative factors that could further explain the stock's recent movement.
Broader market context shows that while Aegis Vopak has performed well in the short term compared to the benchmark Sensex, which has declined by 0.47% over the past week and 0.27% over the past month, the current drop in stock price suggests a disconnect between its recent performance and current trading activity. The stock is trading above its moving averages, which typically indicates a bullish trend; however, the falling investor participation and today's underperformance against the sector may be contributing to the downward pressure on the stock price.
