Why is MEP Infrast. falling/rising?

As of 01-Jul, MEP Infrastructure Developers Ltd is experiencing a decline in its stock price, currently at 2.15, which represents a decrease of 0.04 or 1.83%. The stock has been underperforming significantly, having fallen consecutively for the last nine days, resulting in a total return of -14.68% during this period. Additionally, the stock has shown poor performance over various time frames, with a year-to-date return of -25.86% and a staggering -73.16% return over the past year. The company has not declared results in the last six months, and its financials indicate a weak long-term fundamental strength, with net sales declining at an annual rate of -51.44% and operating profit plummeting by -248.01% over the last five years. Furthermore, 82.7% of promoter shares are pledged, which adds downward pressure on the stock price in a falling market.
In the broader market context, the stock's performance is notably worse than the benchmark, as it has underperformed the Sensex, which has gained 2.00% over the past week, while MEP Infrastructure has dropped by 8.51%. This consistent underperformance against the benchmark over the last three years highlights the stock's riskiness, especially given its negative results for the last eight consecutive quarters. The falling investor participation, with a delivery volume that has decreased by 78.14% against the five-day average, further indicates a lack of confidence among investors, contributing to the stock's downward trajectory.
