Why is Transpek Inds. falling/rising?

As of 26-Jun, Transpek Industry Ltd's stock price is currently at Rs 1,630.00, reflecting a decrease of Rs 16.0 or 0.97%. The stock has been on a downward trend, having fallen consecutively for the last five days, resulting in a total decline of 5.51% over the past week. Today's performance indicates that it underperformed its sector by 1.48%, with an intraday low of Rs 1,600.1. Despite reporting a significant growth in net profit of 80.75% and a strong operating profit to interest ratio, the stock's long-term fundamentals are weak, evidenced by a -13.44% CAGR growth in operating profits over the last five years and a low return on equity of 6.5%. Additionally, the stock is trading at a premium compared to its peers, which may deter investors.
In the broader market context, the stock's performance has lagged behind the benchmark, with a return of -8.91% over the past year compared to the Sensex's gain of 6.46%. While the market has shown resilience with a 4.11% return in the last year, Transpek Industry Ltd's significant underperformance may reflect a lack of confidence from domestic mutual funds, which hold no stake in the company. This lack of institutional support, combined with falling investor participation and liquidity issues, suggests a challenging environment for the stock, contributing to its recent decline.
