Why is Reliable Data falling/rising?

As of 24-Sep, Reliable Data Services Ltd is experiencing a decline in its stock price, currently at 121.05, which reflects a decrease of 1.9 or 1.55%. The stock has been underperforming, having fallen for three consecutive days with a total decline of 2.97% during this period. Today's trading saw the stock reach an intraday high of Rs 128.3 but also dip to a low of Rs 118.6, indicating volatility. While the stock has shown impressive returns over the longer term, including a 70.40% increase year-to-date and a 47.80% rise over the past year, it has underperformed the sector today by 0.89%. Additionally, there has been a notable decrease in investor participation, with delivery volume dropping by 12.19% compared to the five-day average.
In the broader market context, the stock's recent performance contrasts with the benchmark Sensex, which has only declined by 1.18% over the past week. Despite the stock's strong historical performance and attractive valuation metrics, such as a high return on capital employed and significant growth in net sales, the current market sentiment appears to be negative, contributing to the recent price drop. The stock's ability to generate substantial returns over the past year, even as the broader market has faced challenges, suggests that while it has strong fundamentals, short-term pressures are currently affecting its price movement.
