Why is Semac Construct falling/rising?

As of 12-Aug, Semac Construction Ltd's stock price is currently at 505.00, reflecting a decrease of 5.0, or 0.98%. The stock has been underperforming, having fallen consecutively for the last two days, resulting in a total decline of 3.26% during this period. Additionally, the stock opened with a loss of 2.35% today and has shown erratic trading patterns, not trading on 2 out of the last 20 days. The stock's performance over the past week and month has also been negative, with declines of 6.47% and 7.24%, respectively, while the year-to-date performance remains positive at 27.30%. However, the recent drop in delivery volume by 92.67% against the 5-day average indicates a significant decrease in investor participation, contributing to the stock's downward movement.
In the broader market context, Semac Construction's recent performance contrasts with the Sensex, which has only declined by 0.59% over the past week and 2.75% over the past month. This suggests that while the overall market has been relatively stable, Semac Construction has faced more substantial losses. The stock's performance over the past year shows a decline of 8.36%, while the Sensex has increased by 0.74%, indicating that Semac is lagging behind the benchmark. The stock's moving averages indicate it is currently lower than the 5-day and 20-day averages, which may further signal bearish sentiment among investors.
