Why is Delta Auto. falling/rising?

As of 24-Sep, Delta Autocorp Ltd's stock price is rising, currently at 69.30, reflecting an increase of 1.1 or 1.61%. The stock has outperformed its sector today by 2.76%, and over the past week, it has shown a return of +2.29%, while the benchmark Sensex has declined by -1.08%. However, the stock's delivery volume has fallen significantly, down by 57.45% against the 5-day average, which indicates a decrease in investor participation. Additionally, while the stock is currently above its 5-day and 20-day moving averages, it remains below its 50-day, 100-day, and 200-day moving averages, suggesting mixed momentum in the short to medium term.
In the broader market context, Delta Autocorp's short-term performance contrasts positively with the Sensex, which has shown a negative return over the same period. The stock's 1-month return of +3.12% also surpasses the Sensex's +0.75%, indicating relative strength. Despite the recent rise in price, the falling investor participation could be a concern for future performance, as liquidity remains adequate for trading, but the significant drop in delivery volume may signal caution among investors. Overall, while the stock is currently experiencing upward movement, the declining interest could impact its sustainability in the near term.
