Why is IMEC Services falling/rising?

As of 19-Aug, IMEC Services Ltd is experiencing a decline in its stock price, currently at Rs 196.85, which reflects a decrease of 4.0 points or 1.99%. The stock has underperformed its sector by 2.7% today and has seen a consecutive fall over the last two days, resulting in a total decline of 3.93% during this period. Despite a strong performance over the past year, with an impressive return of 2342.31%, the company is facing challenges such as operating losses and a weak long-term fundamental strength, indicated by a negative annual growth rate in net sales of -35.90% over the last five years. Additionally, 65.48% of promoter shares are pledged, which can exert downward pressure on the stock price in a falling market.
In the broader market context, the stock's recent performance contrasts with the benchmark Sensex, which has gained 1.76% over the past week, while IMEC Services has seen a slight decline of 0.08%. This underperformance in the short term, coupled with the company's weak ability to service its debt and negative EBITDA, raises concerns among investors. Although there has been rising investor participation, as evidenced by a 48.08% increase in delivery volume, the overall sentiment remains cautious due to the company's financial instability and the high percentage of pledged shares.
