Why is Vedanta falling/rising?

As of 28-Aug, Vedanta Ltd. is experiencing a decline in its stock price, currently at 424.25, which reflects a decrease of 4.0 points or 0.93%. The stock has been underperforming recently, with a consecutive fall over the last two days resulting in a total decline of 5.8%. Additionally, it is trading below all its moving averages, indicating a bearish trend. The stock's performance over the past week shows a drop of 5.05%, while its one-month return is down 3.14%. Despite a high dividend yield of 12.03% and strong long-term fundamentals, including a robust Return on Capital Employed (ROCE) of 30.57%, the stock's price is pressured by a significant pledge of promoter shares, which contributes to downward pressure in a falling market.
In the broader market context, Vedanta's recent performance contrasts with the benchmark Sensex, which has declined by only 2.34% over the past week. This underperformance is notable as Vedanta's year-to-date return is down 4.51%, while the Sensex has gained 2.48% during the same period. The falling investor participation, with a 29.85% drop in delivery volume compared to the five-day average, further exacerbates the stock's decline. Overall, while Vedanta has strong fundamentals and a solid market position, the combination of negative sentiment from pledged shares and recent price movements has led to its current downward trajectory.
