Why is De Neers Tools falling/rising?

As of 17-Sep, De Neers Tools Ltd is experiencing a significant decline in its stock price, currently at 209.05, reflecting a decrease of 52.25 or 20.0%. The stock has underperformed its sector by 20.71% today and is trading below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages. Over the past week, the stock has dropped by 23.56%, and over the past month, it has decreased by 28.42%. However, there has been a notable increase in investor participation, with delivery volume rising by 441.67% against the 5-day average, indicating some interest despite the overall negative performance. Unfortunately, there is no information available regarding positive or negative factors that could further explain the stock's recent movement.
In the broader market context, De Neers Tools' performance contrasts sharply with the Sensex, which has gained 1.43% over the past week and 2.84% over the past month. This stark difference highlights the stock's struggle, as it has not only underperformed in the short term but also year-to-date, where it has fallen by 35.83% compared to the Sensex's gain of 7.13%. The liquidity of the stock remains adequate for trading, as it is based on 2% of the 5-day average traded value, but the overall market sentiment appears to be unfavorable for De Neers Tools at this time.
