Why is Vascon Engineers falling/rising?

As of 09-Jul, Vascon Engineers Ltd is currently priced at 53.45, reflecting an increase of 0.89 or 1.69%. The stock has been gaining momentum, having outperformed its sector by 1.7% today and achieving a consecutive gain over the last two days with a total return of 2.63%. However, the stock has underperformed in the longer term, with a 1-year return of -27.39% compared to the Sensex's 3.96%. Despite a healthy operating profit growth rate of 94.12% and a low debt-to-equity ratio, concerns about poor management efficiency, as indicated by a low return on capital employed (ROCE) of 6.71%, and a significant portion of promoter shares being pledged (27.73%) may be contributing to investor caution.
In the broader market context, the stock's recent performance contrasts with the benchmark, as it has declined by 1.02% over the past week while the Sensex has gained 0.15%. Year-to-date, Vascon Engineers has shown a modest increase of 0.85%, significantly lagging behind the Sensex's 6.91% rise. This underperformance over the past year, combined with falling investor participation—evidenced by a 36.05% drop in delivery volume—suggests that while there may be short-term gains, the stock faces challenges that could hinder its recovery in the broader market.
