Why is Vinny Overseas falling/rising?

As of 04-Jul, Vinny Overseas Ltd's stock price is currently at 1.35, reflecting a decrease of 0.02 or 1.46%. The stock has underperformed its sector today by 2.28% and has experienced a consecutive decline over the last two days, resulting in a total drop of 2.88%. In terms of returns, the stock has seen a significant decline of 56.75% over the past year, while it has also underperformed the benchmark Sensex, which has gained 4.23% in the same period. Despite a very attractive valuation with a Price to Book Value of 0.8 and a rising promoter stake indicating confidence in the company, the stock's long-term fundamental strength appears weak, with a -52.67% CAGR growth in operating profits over the last five years.
Broader market context shows that Vinny Overseas has underperformed the Sensex significantly, with a 1-month return of -6.90% compared to the Sensex's gain of 3.01%. This trend of underperformance is consistent, as the stock has also lagged behind the benchmark over the last three years and one year. The weak operating profit margins and flat results reported in the last quarter further contribute to the negative sentiment surrounding the stock, overshadowing the positive factors such as rising investor participation and increased promoter confidence.
