Why is Rajputana Bio. falling/rising?

As of 19-Sep, Rajputana Biodiesel Ltd is experiencing a price increase, currently at 285.85, which reflects a rise of 3.7 or 1.31%. The stock has shown strong performance recently, with a 1-week return of +2.82% and a 1-month return of +17.85%, significantly outperforming the Sensex, which has only increased by 0.85% and 1.39% over the same periods, respectively. Additionally, the stock is trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating a positive trend. However, there has been a decline in investor participation, with delivery volume dropping by 27.71% compared to the 5-day average, which may suggest some caution among investors.
In the broader market context, Rajputana Biodiesel's recent performance contrasts with the year-to-date return of -8.72%, while the Sensex has gained 7.11% during the same period. This divergence highlights the stock's volatility and potential recovery phase despite its longer-term underperformance. The liquidity of the stock remains adequate for trading, as it is based on 2% of the 5-day average traded value. Overall, while the stock is currently rising, the falling investor participation could be a concern for its sustainability in the near term.
