Why is Semac Construct falling/rising?

As of 25-Jul, Semac Construction Ltd's stock price is currently at Rs 522.00, reflecting a decrease of Rs 26.5 or 4.83%. The stock opened the day with a loss of 4.83% and touched an intraday low of Rs 522, indicating significant downward pressure. Despite reaching a day's high of Rs 567 earlier, the overall performance today underperformed the sector by 2.6%. Over the past week, the stock has declined by 3.51%, while it has shown a positive return of 23.90% over the last month. However, the company faces challenges, including operating losses and a weak ability to service its debt, which contribute to its negative sentiment in the market.
In the broader market context, the Sensex has only fallen by 0.36% over the past week, suggesting that Semac Construction's decline is more pronounced than the overall market trend. While the stock has generated a return of 31.59% year-to-date, its performance over the last year has been negative at -7.61%, contrasting sharply with the Sensex's positive return of 1.78% in the same period. The company's weak long-term fundamental strength, highlighted by a negative EBITDA and low profitability per unit of shareholders' funds, adds to the risk perception among investors, leading to the current downward movement in its stock price.
