Why is PTC Industries falling/rising?

As of 19-Sep, PTC Industries Ltd is experiencing a decline in its stock price, currently at Rs 14,941.30, which reflects a decrease of Rs 571.3 or 3.68%. Today's performance indicates that the stock has underperformed its sector by 2.29% and has seen a trend reversal after four consecutive days of gains. The stock touched an intraday low of Rs 14,757.35, marking a 4.87% drop. Despite a strong historical performance, with a 532.13% increase over the past three years and consistent returns over the last year, the company faces challenges such as weak long-term fundamental strength, indicated by an average Return on Equity (ROE) of 5.78% and a significant decline in PAT for the latest quarter.
In the broader market context, PTC Industries has outperformed the Sensex in the short term, with a 5.75% increase over the past week compared to the benchmark's 0.88%. However, the recent decline in stock price may be attributed to falling investor participation, as evidenced by a 5.22% drop in delivery volume against the five-day average. Additionally, the company's high valuation relative to its peers, coupled with flat quarterly results and a low debtors turnover ratio, raises concerns among investors, contributing to the stock's current downward movement.
