Why is Sterlite Tech. falling/rising?

As of 30-Jul, Sterlite Technologies Ltd is experiencing a decline in its stock price, currently at Rs 122.55, which represents a decrease of Rs 5.85 or 4.56%. The stock has underperformed its sector by 4.69% today and has fallen after three consecutive days of gains, reaching an intraday low of Rs 121.05. Despite this drop, the stock has shown strong performance over the past week, with a return of 3.90%, and a significant year-to-date increase of 43.11%. The company has reported positive results in the last two quarters, with notable growth in net sales and operating profit, which may have contributed to previous gains but are not sufficient to counter the current decline.
Broader market context indicates that while Sterlite Technologies has outperformed the broader market, which has seen negative returns of -2.34% over the past year, the stock's recent performance has been affected by today's downturn. The stock's trading is above its moving averages, suggesting a generally positive trend, but the current decline reflects a short-term reversal in sentiment. The increase in investor participation, as indicated by rising delivery volumes, suggests ongoing interest in the stock, although today's performance may be influenced by broader market conditions and profit-taking after recent gains.
