Why is Semac Construct falling/rising?

As of 20-Oct, Semac Construction Ltd is experiencing a price increase, with its current price at Rs 475.00, reflecting a rise of Rs 10.00 or 2.15%. The stock has shown a positive trend recently, gaining for three consecutive days and achieving a total return of 7.95% during this period. However, it has underperformed in the longer term, with a 1-week decline of 0.68% and a 1-month decline of 7.23%. Despite these setbacks, the stock has performed well year-to-date, with a return of 19.74%. Notably, the stock's delivery volume has decreased significantly, indicating falling investor participation, which could impact future price movements.
In the broader market context, the Sensex has outperformed Semac Construction Ltd in the short term, with a 1-week return of 2.47% compared to the stock's decline. This suggests that while the stock is currently rising, it is lagging behind the overall market performance. The stock's liquidity remains adequate for trading, but the recent drop in delivery volume could signal caution among investors. Overall, the stock's recent gains may be attributed to short-term momentum, despite its longer-term challenges and the contrasting performance against the benchmark index.
