Why is Adtech Systems falling/rising?

As of 26-Jun, Adtech Systems Ltd is experiencing a decline in its stock price, currently at Rs 69.00, which reflects a decrease of 1.0 (-1.43%). The stock has underperformed its sector today by 1.37% and has been on a downward trend for the past two days, with a total decline of 1.97%. It also reached an intraday low of Rs 67.5, marking a decrease of 3.57%. Over the past week, the stock has fallen by 2.80%, and it has shown a significant decline of 25.81% year-to-date. The company's weak long-term fundamentals, indicated by a -13.30% CAGR growth in net sales over the last five years and a low average return on equity of 8.59%, contribute to its poor performance. Additionally, the fact that 29.68% of promoter shares are pledged adds downward pressure on the stock, particularly in a falling market.
In the broader market context, Adtech Systems has consistently underperformed against the benchmark, with a return of -17.37% over the past year compared to the Sensex's gain of 6.46%. This trend of underperformance has been evident over the last three years, where the stock has lagged behind the BSE 500 in each annual period. While there has been a rise in investor participation, as evidenced by a 96.8% increase in delivery volume, the overall market sentiment remains negative, further exacerbating the stock's decline.
