Why is BHEL falling/rising?

As of 18-Sep, Bharat Heavy Electricals Ltd. (BHEL) is experiencing a slight increase in its stock price, currently at 234.35, reflecting a change of 0.1 or 0.04% upward. The stock has shown a positive performance over the last four days, gaining 2.47% in that period, although it underperformed its sector by 0.35% today. In terms of returns, BHEL has outperformed the Sensex over the past week and month, with increases of 2.38% and 8.17%, respectively. However, the stock has a concerning year-to-date return of only 2.20% and a significant decline of 11.63% over the past year. The company has a low debt-to-equity ratio of 0.03, indicating financial stability, and has seen a healthy long-term growth in operating profit at an annual rate of 18.96%. Despite high institutional holdings at 24.86%, which have increased by 1.32% over the previous quarter, the company is facing challenges with a negative profit after tax and low operating profit to interest ratio.
In the broader market context, BHEL's recent gains contrast with the Sensex, which has risen by 1.80% over the past week and 2.14% over the past month. While the stock has shown resilience in the short term, its long-term performance remains a concern, particularly given its negative return over the past year compared to the Sensex's minimal gain. The falling investor participation, indicated by a 55.76% drop in delivery volume against the five-day average, suggests a potential lack of confidence among retail investors. Furthermore, the stock's high valuation, with a price-to-book value of 3.3 and a PEG ratio of 54.4, raises questions about its sustainability in the face of declining profitability metrics.
