Why is Reliable Data falling/rising?

As of 19-Nov, Reliable Data Services Ltd's stock price is currently at Rs 135.00, reflecting a decline of Rs 6.5 or 4.59%. The stock has been underperforming, having fallen for four consecutive days, resulting in a total drop of 14.23% during this period. Today, the stock opened with a loss of 2.65% and reached an intraday low of Rs 135. The trading volume has also decreased significantly, with delivery volume dropping by 65.38% compared to the five-day average. Despite a strong year-to-date return of 90.03%, the stock's recent performance has been lackluster, particularly in the last week where it has declined by 11.91%.
In the broader market context, the Sensex has shown a positive return of 0.85% over the past week, contrasting with Reliable Data's significant decline. While the IT - Software sector has gained by 2.78%, Reliable Data's performance has lagged behind, indicating a sector-wide strength that the company has not capitalized on. The stock's volatility today was high, with an intraday volatility of 5.24%, suggesting uncertainty among investors. Overall, the combination of falling investor participation and the stock's inability to keep pace with both its sector and the broader market has contributed to its recent price decline.
