Why is BHEL falling/rising?

As of 22-Aug, Bharat Heavy Electricals Ltd. (BHEL) is experiencing a slight increase in its stock price, currently at 218.55, with a change of 0.05 (0.02%) upward. However, the stock has underperformed in the short term, with a 1-week return of -1.42% and a 1-month return of -12.74%. Today's price summary indicates that BHEL is trading below its moving averages across various time frames, suggesting a bearish trend. Additionally, there has been a significant drop in investor participation, with delivery volume falling by 41.49% compared to the 5-day average. While the company has a low debt-to-equity ratio and healthy long-term growth in operating profit, it is facing challenges with declining net sales and profits, leading to a very expensive valuation relative to its peers.
In the broader market context, BHEL's performance contrasts sharply with the benchmark Sensex, which has gained 0.88% over the past week. The stock's year-to-date return of -4.69% also lags behind the Sensex's positive return of 4.05%. Despite high institutional holdings, which have increased by 1.32% over the previous quarter, the stock's significant decline of -27.06% over the past year indicates a lack of confidence among investors. This underperformance, coupled with the company's recent financial struggles, suggests that BHEL is facing considerable headwinds in the current market environment.
