Why is Gratex Industrie falling/rising?

As of 28-Oct, Gratex Industries Ltd is experiencing a price increase, with its current price at 20.95, reflecting a change of 0.99 or 4.96% upward. The stock has shown a positive performance today, outperforming its sector by 5.71%, and has been on a consecutive gain for the last two days, resulting in a total return of 10.09% during this period. Despite a year-to-date decline of 20.10%, the stock has seen a modest increase of 4.75% over the past year. However, it is important to note that there is a significant drop in investor participation, as evidenced by a 75.37% decrease in delivery volume compared to the five-day average, which may indicate some underlying concerns despite the recent price rise.
In the broader market context, Gratex Industries' short-term performance over the past month shows a gain of 3.46%, which is notably lower than the Sensex's increase of 5.22% during the same period. This suggests that while the stock is currently rising, it is still lagging behind the benchmark index in terms of overall performance. Additionally, the stock's liquidity appears adequate for trading, but the erratic trading pattern, with no trades on two out of the last twenty days, could contribute to volatility and uncertainty in its price movements.
