Why is Semac Construct falling/rising?

As of 28-Oct, Semac Construction Ltd's stock price is currently at 424.00, reflecting a decline of 11.3 points or 2.6%. The stock has been on a downward trend, having underperformed its sector by 1.5% today and experiencing consecutive losses over the past four days, resulting in a total decline of 11.11% in that period. Although the stock opened with a gain of 3.38% today and reached an intraday high of Rs 450, it also touched a low of Rs 420.6, indicating significant volatility. Additionally, the stock's performance over the past week and month shows a decline of 11.11% and 17.97%, respectively, while year-to-date and one-year returns remain positive at 6.88% and 6.00%. There is a notable decrease in investor participation, with delivery volume falling by 71.27% against the five-day average, which may be contributing to the stock's recent struggles.
Broader Market Context: In comparison to the benchmark Sensex, which has gained 0.24% over the past week and 5.22% over the past month, Semac Construction's recent performance has been significantly weaker. The stock's decline contrasts sharply with the broader market trends, as it has not only underperformed in the short term but also over the longer three-year period, where it has dropped 57.91% compared to the Sensex's gain of 41.14%. This disparity highlights the challenges faced by Semac Construction Ltd in maintaining investor confidence and market traction amidst a generally positive market environment.
