Why is Delta Industrial falling/rising?

As of 16-Jul, Delta Industrial Resources Ltd is experiencing a price increase, currently at 15.04, which reflects a rise of 0.71 or 4.95%. The stock has shown strong performance recently, gaining 15.69% over the last three days and outperforming its sector by 5.18% today. Additionally, the stock has positive returns over the past week and month, with increases of 7.51% and 30.44%, respectively. It is also trading above its moving averages across various time frames, indicating a bullish trend. However, there has been a notable decline in investor participation, with delivery volume dropping by 43.5% compared to the five-day average, which could be a concern for sustained momentum.
In the broader market context, Delta Industrial's recent performance contrasts sharply with the Sensex, which has seen a decline of 1.08% over the past week and a modest increase of 1.02% over the past month. While Delta has outperformed the benchmark significantly in the short term, its year-to-date performance of 6.44% is slightly below the Sensex's 5.75%. This suggests that while the stock is currently on an upward trajectory, it has faced substantial challenges over the past year, with a decline of 52.99%, indicating a volatile history that investors should consider.
