Why is Aegis Vopak Term falling/rising?

As of 21-Jul, Aegis Vopak Terminals Ltd is experiencing a price increase, with its current price at Rs 292.10, reflecting a rise of Rs 4.35 or 1.51%. The stock has shown strong performance recently, with a 1-week return of +13.64% and a 1-month return of +19.13%, significantly outperforming the Sensex, which has seen minimal changes of -0.06% and -0.25% over the same periods. Today's trading saw the stock reach an intraday high of Rs 293.8, while it remains close to its 52-week high, just 3.39% away from Rs 302. However, there has been a notable decline in investor participation, with delivery volume falling by 38.8% against the 5-day average, which may indicate some caution among investors despite the stock's upward movement.
Broader Market Context: The stock's strong short-term performance contrasts sharply with the benchmark Sensex, which has not shown significant gains recently. While Aegis Vopak is trading above all its moving averages, indicating a bullish trend, the decline in delivery volume suggests that the recent price increase may not be fully supported by robust investor interest. This mixed signal could imply that while the stock is currently rising, the sustainability of this upward trend may be questioned if investor participation does not improve.
