Why is Data Pattern falling/rising?

As of 23-Jul, Data Patterns (India) Ltd is experiencing a decline in its stock price, currently at Rs 2,782.00, reflecting a decrease of Rs 28.0 or 1.0%. Today's price summary indicates that the stock has underperformed its sector by 1.45%, with an intraday low of Rs 2,748.05, marking a drop of 2.2%. Over the past week, the stock has seen a return of -3.95%, and over the past month, it has decreased by 8.10%. Despite a strong year-to-date performance of +12.66%, the stock has underperformed the market over the last year, generating a return of -10.02% compared to the Sensex's +2.86%. The company has a low debt-to-equity ratio and has shown healthy long-term growth in net sales, but it is trading at a premium valuation, which may be contributing to the recent price decline.
In the broader market context, Data Patterns' recent performance contrasts sharply with the benchmark, as it has underperformed significantly over the last year while the BSE500 has generated a return of 1.79%. The stock's liquidity remains adequate for trading, but a notable decline in investor participation, with delivery volume falling by 18.72% against the 5-day average, suggests waning interest among investors. Although high institutional holdings indicate confidence from larger investors, the stock's expensive valuation and negative returns over the past year may be causing caution among potential buyers, leading to the current downward price movement.
