Why is Supreme Inds. falling/rising?

As of 30-Jul, Supreme Industries Ltd's stock price is currently at Rs 4,177.55, reflecting a decline of Rs 134.45 or 3.12%. The stock has been underperforming recently, having fallen for the last two days with a total decline of 3.74%. It touched an intraday low of Rs 4,150, indicating significant selling pressure. Additionally, the stock's performance over the past month shows a decrease of 4.64%, while it has declined 21.64% over the past year. Despite strong long-term fundamentals, including a healthy average return on equity of 22.73% and a low debt-to-equity ratio, the recent price movement suggests that investor sentiment may be wavering, particularly as delivery volume has decreased by 8.58% against the five-day average.
Broader market context indicates that the stock has underperformed the benchmark Sensex, which has declined by 1.50% over the past week while Supreme Industries Ltd has gained 1.10%. This suggests that the stock's recent struggles are not entirely reflective of broader market trends, as it has shown resilience in the short term compared to the benchmark. However, the overall year-to-date performance of the stock is concerning, with a decline of 11.28% compared to the Sensex's gain of 4.28%. The high institutional holdings at 36.54% may provide some stability, but the falling investor participation and recent price declines indicate a cautious outlook among investors.
