Why is Delta Industrial falling/rising?

As of 30-Jun, Delta Industrial Resources Ltd is experiencing a price increase, with its current price at 12.60, reflecting a change of 0.6 or 5.0% upward. The stock has shown a performance today that outperformed its sector by 4.48%. However, despite this positive movement, the stock has a concerning trend with a year-to-date decline of 10.83% and a significant drop of 61.81% over the past year. Additionally, the stock's delivery volume has fallen dramatically by 95.59% compared to the 5-day average, indicating a decrease in investor participation. There is no information available regarding positive or negative factors that could further explain the stock's recent movement.
In the broader market context, Delta Industrial's short-term return over the past week is +0.88%, which is lower than the benchmark Sensex's return of +2.09%. This suggests that while the stock has made some gains recently, it is still lagging behind the overall market performance. Over the past month, Delta's return of +2.19% also trails the Sensex's +2.65%, indicating a consistent underperformance relative to the benchmark. The stock's liquidity is noted to be sufficient for trading, but the overall decline in investor participation may be a concern for future price movements.
