Why is Power Grid Corpn falling/rising?

As of 28-Aug, Power Grid Corporation of India Ltd is experiencing a decline in its stock price, currently at Rs 274.40, which reflects a decrease of Rs 5.4 or 1.93%. The stock has underperformed its sector by 0.67% today and has been on a downward trend, losing 3.43% over the last two days. It has also been trading below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages. Over the past week, the stock has declined by 3.38%, and in the last month, it has fallen by 6.36%. Despite a high institutional holding of 45.06%, the company faces challenges such as a high Debt to EBITDA ratio of 3.31 times and poor long-term growth, with operating profit growing at only 3.96% annually over the last five years. Additionally, the stock has generated a return of -18.04% over the past year, significantly underperforming the market.
In the broader market context, the Sensex has declined by 2.34% over the past week and 1.00% over the last month, indicating that while the market is also facing downward pressure, Power Grid's decline is more pronounced. The stock's performance has been notably weaker compared to the benchmark, with a year-to-date return of -11.08% against the Sensex's gain of 2.48%. This suggests that investor sentiment towards Power Grid is particularly negative, exacerbated by flat financial results and a very expensive valuation relative to its peers. The liquidity of the stock remains adequate, but the combination of high debt levels and disappointing growth metrics continues to weigh heavily on its price performance.
