Why is Delta Industrial falling/rising?

As of 08-Jul, Delta Industrial Resources Ltd is experiencing a slight decline in its stock price, currently at 13.99, down by 0.01 or 0.07%. The stock's performance today is in line with its sector, but it has shown a significant drop in investor participation, with delivery volume falling by 73.78% against the 5-day average. Over the past week, the stock has increased by 9.73%, and over the past month, it has risen by 18.46%. However, it has a year-to-date decline of 0.99% and a substantial year-over-year drop of 61.19%. The stock is currently trading higher than its 5-day, 20-day, 50-day, and 100-day moving averages, but it remains below its 200-day moving average.
In the broader market context, the Sensex has shown a modest increase of 0.02% over the past week, while Delta Industrial's short-term return significantly outperforms this benchmark. Despite the stock's recent gains, the overall year-to-date performance is lagging behind the Sensex, which has risen by 7.13% in the same period. The liquidity of the stock is deemed sufficient for trading, but the falling investor participation could indicate a lack of confidence or interest, which may contribute to the stock's recent price movement.
