Why is ADC India falling/rising?

As of 15-Jul, ADC India Communications Ltd is experiencing a decline in its stock price, currently at Rs 1,185.00, reflecting a decrease of Rs 71.0 or 5.65%. The stock has underperformed its sector by 6.43% today, reaching an intraday low of Rs 1,180. The stock's performance over the past week shows a decline of 5.35%, while it has seen a significant drop of 39.74% over the past year. Despite a high dividend yield of 4.38% and healthy long-term growth in operating profit, the stock's recent movement is negatively impacted by a substantial fall in quarterly profits and a high percentage of pledged promoter shares, which adds downward pressure in a falling market.
In the broader market context, the Sensex has only declined by 1.36% over the past week, indicating that ADC India is underperforming relative to the benchmark. While the stock has shown a positive return of 17.33% over the past month, its year-to-date performance is notably poor at -27.58%, contrasting sharply with the Sensex's gain of 5.67%. This underperformance, coupled with negative quarterly results and a significant drop in investor participation, suggests that market sentiment is currently unfavorable for ADC India, contributing to its declining stock price.
