Why is Indian Hume Pipe falling/rising?

As of 19-Jun, Indian Hume Pipe Company Ltd's stock price is currently at Rs 397.80, reflecting a decrease of Rs 13.75 or 3.34%. The stock has been on a downward trend, having fallen for the last six consecutive days with a total decline of 12.41%. Although it opened today with a gain of 9.18% and reached an intraday high of Rs 449.35, it also experienced significant volatility, trading within a wide range of Rs 53.35. The stock's performance over the past week shows a decline of 9.89%, while its year-to-date return remains positive at 10.10%. However, the company's weak long-term fundamentals, including a negative CAGR growth in operating profits and a high Debt to EBITDA ratio, contribute to the bearish sentiment surrounding the stock.
In the broader market context, the Indian Hume Pipe Company Ltd has underperformed the Sensex, which has only declined by 0.40% over the same one-week period. The construction material sector, in which the company operates, has also seen a decrease of 2.57%. Additionally, the falling investor participation, indicated by a significant drop in delivery volume, suggests a lack of confidence among investors. Despite the company's attractive valuation and recent profit growth, the high percentage of pledged promoter shares adds downward pressure in a falling market, further exacerbating the stock's decline.
