Why is Sarthak Industri falling/rising?

As of 15-Sep, Sarthak Industries Ltd's stock price is currently at Rs 40.77, reflecting an increase of Rs 1.51 or 3.85%. The stock has shown a trend reversal today, gaining after two consecutive days of decline. It reached an intraday high of Rs 41.39, representing a rise of 5.43%, although it also experienced a low of Rs 37.55, which was a decrease of 4.36%. Despite the positive movement today, the stock has underperformed in the short term, with a 1-week return of -2.88% and a 1-month return of -8.55%. However, it has performed well year-to-date, with a return of +36.35%. Notably, there has been a significant drop in investor participation, with delivery volume falling by 80.55% against the 5-day average, indicating a potential concern for future trading activity.
In the broader market context, while Sarthak Industries has outperformed its sector by 3.7% today, it has lagged behind the benchmark Sensex over the past week and month, which saw gains of 1.24% and 1.47%, respectively. The stock's performance over the past year has been strong, with a return of +72.39%, contrasting with the Sensex's decline of -1.33%. This suggests that while Sarthak Industries has had a robust long-term performance, its recent short-term struggles may be affecting investor sentiment, particularly in light of the declining delivery volumes and the stock's fluctuating trading range.
