Why is Northern ARC falling/rising?

As of 17-Sep, Northern ARC Capital Ltd is experiencing a decline in its stock price, currently at 262.60, which reflects a decrease of 2.95 or 1.11%. The stock has underperformed its sector by 1.05% today and has been on a downward trend for the last two days, resulting in a total loss of 1.39% during this period. Despite this recent decline, the stock has shown strong performance over the past week and month, with returns of 4.83% and 13.31%, respectively. Additionally, the company has demonstrated robust long-term growth, with net sales increasing at an annual rate of 38.10%, contributing to a positive outlook despite the current price drop.
In the broader market context, the Sensex has increased by 1.56% over the past week and 2.60% over the past month, indicating that while Northern ARC has outperformed the benchmark in these time frames, its recent performance has not aligned with this trend. The stock's liquidity remains adequate, but there is a noted decline in investor participation, with delivery volume falling by 2.3% against the five-day average. This decrease in trading activity may be contributing to the stock's recent price decline, even as the company maintains a healthy long-term growth trajectory and attractive valuation metrics.
