Why is SER Industries falling/rising?

As of 19-Sep, SER Industries Ltd is experiencing a price increase, with its current price at Rs. 270.95, reflecting a rise of 5.3 or 2.0%. The stock has reached a new 52-week and all-time high today, and it has been on a consecutive gain streak for the last 21 days, accumulating a remarkable 51.28% return during this period. Additionally, the stock has outperformed its sector by 2.66% today and opened with a gain of 2%. It is also trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages. However, there has been a notable decline in investor participation, with delivery volume dropping by 83.82% against the 5-day average, indicating a potential concern regarding sustained interest in the stock.
In the broader market context, SER Industries has significantly outperformed the benchmark Sensex over the past week and month, with returns of 10.39% and 54.30%, respectively, compared to the Sensex's 0.88% and 1.20% gains. This strong performance relative to the benchmark suggests that the stock is gaining traction among investors despite the recent drop in delivery volume. The liquidity of the stock remains adequate for trading, which may help maintain its upward momentum in the short term. Overall, while the stock is rising, the decline in investor participation could be a factor to monitor moving forward.
