Why is Delta Industrial falling/rising?

As of 08-Oct, Delta Industrial Resources Ltd is experiencing a significant rise in its stock price, currently at Rs 15.70, reflecting an increase of Rs 2.2 or 16.3%. The stock has outperformed its sector by 16.84% today and has shown a consecutive gain over the last two days, resulting in a total return of 20.4% during this period. Additionally, the stock has been trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating a strong upward trend. However, there has been a notable decline in investor participation, with delivery volume dropping by 99.38% compared to the 5-day average, which may raise concerns about sustainability in the stock's upward movement.
In the broader market context, Delta Industrial's short-term performance over the past week shows a return of 12.22%, significantly outperforming the Sensex, which only gained 0.98% in the same period. Over the past month, the stock has also outperformed the benchmark, with a return of 10.64% compared to the Sensex's 1.22%. Despite the positive short-term performance, the stock's long-term performance remains a concern, as it has declined by 13.12% over the past year while the Sensex has only slightly increased by 0.17%. This contrast highlights the stock's volatility and the potential risks associated with its recent gains.
