Why is Semac Construct falling/rising?

As of 10-Oct, Semac Construction Ltd is currently priced at 480.00, with no change in price, reflecting a 0.00% movement. The stock has experienced a decline of 1.84% over the past week and 11.93% over the past month, while it has shown positive performance year-to-date with a gain of 21.00%. Today's trading performance is reported as inline with the sector, although there has been erratic trading, with the stock not trading on one day out of the last 20. Notably, there has been a significant increase in investor participation, with delivery volume rising by 127.27% against the 5-day average, indicating growing interest. However, the absence of specific positive or negative factors limits a comprehensive analysis of the stock's recent movements.
In the broader market context, Semac Construction's recent performance contrasts sharply with the benchmark Sensex, which has gained 1.59% over the past week and 1.32% over the past month. While Semac has outperformed the benchmark year-to-date and over the past year, its significant declines over the 3-year period (-46.22%) compared to the Sensex's gain of 42.26% suggest a longer-term struggle. The stock's current liquidity, based on 2% of the 5-day average traded value, indicates it is liquid enough for trading, but the overall market sentiment appears to favor the benchmark, contributing to the stock's recent underperformance.
