Why is Sterlite Tech. falling/rising?

As of 19-Nov, Sterlite Technologies Ltd is experiencing a decline in its stock price, currently at Rs 112.50, which represents a decrease of Rs 2.25 or 1.96%. The stock has been underperforming, having fallen consecutively for the last three days, resulting in a total decline of 5.38% during this period. Additionally, the stock's performance over the past week and month shows a decrease of 0.27% and 2.89%, respectively, while it has outperformed the market over the year with a return of 30.02%. Despite positive quarterly results and a significant increase in profits, the stock is currently trading below its short-term moving averages, and there has been a notable drop in investor participation, with delivery volume falling by 21.16% against the five-day average.
In the broader market context, the stock's recent performance contrasts with the Sensex, which has gained 0.85% over the past week and 1.47% over the past month. This indicates that while the overall market is experiencing upward momentum, Sterlite Technologies Ltd is lagging behind. The company's long-term fundamentals are concerning, with a negative CAGR growth in operating profits over the last five years and a high Debt to EBITDA ratio, which may be contributing to investor caution. Although there is high institutional ownership and the stock has shown strong returns over the past year, the recent trends suggest that investors are wary of the company's ability to maintain its performance amidst these challenges.
