Why is Indian Hume Pipe falling/rising?

As of 22-Jul, Indian Hume Pipe Company Ltd is experiencing a decline in its stock price, currently at Rs 430.90, which reflects a decrease of Rs 10.35 or 2.35%. The stock has underperformed its sector by 1.33% today and has been on a consecutive downward trend for the last three days, resulting in a total decline of 5.23% during this period. Despite a positive performance over the past month with a return of 5.51%, the stock's recent movement is influenced by a decrease in investor participation, as evidenced by a 13.73% drop in delivery volume compared to the five-day average. Additionally, while the stock has shown consistent returns over the last three years, its long-term fundamental strength is weak, with a negative CAGR growth in operating profits over the last five years and a high Debt to EBITDA ratio of 2.83 times.
In the broader market context, the stock's short-term performance has been notably weaker than the benchmark, with a 1-week return of -2.90% compared to the Sensex's -0.47%. This underperformance is compounded by the fact that 30.69% of promoter shares are pledged, which can exert additional downward pressure in a falling market. Although the company has a relatively attractive valuation with a Price to Book Value of 1.6 and has generated a return of 3.20% over the past year, the recent flat results and declining profitability metrics, such as a 24.4% drop in PAT, contribute to the negative sentiment surrounding the stock.
