Why is IMEC Services falling/rising?

As of 21-Aug, IMEC Services Ltd is experiencing a decline in its stock price, currently at Rs 189.10, reflecting a decrease of 3.85 (-2.0%). The stock has been underperforming, having fallen consecutively for the last four days, resulting in a total decline of 7.71% over the past week. Today's performance indicates that it opened with a loss of 2% and has traded flat at this price throughout the day. While the company has reported positive results over the last three quarters, including increased net sales and profit after tax, it faces significant challenges such as operating losses and a weak long-term growth outlook, with net sales declining at an annual rate of 35.90% over the past five years. Additionally, 65.48% of promoter shares are pledged, which can exert further downward pressure on the stock price in a falling market.
In the broader market context, IMEC Services' recent performance contrasts sharply with the benchmark, as the Sensex has gained 1.74% over the past week while IMEC has lost 7.71%. Despite its impressive long-term returns, including a staggering 2246.15% increase over the past year, the stock's current trajectory reflects investor concerns about its fundamental weaknesses, particularly its negative EBITDA and poor ability to service debt. The significant drop in delivery volume, which has decreased by 82.53% against the five-day average, suggests a lack of investor confidence, further contributing to the stock's decline.
