Why is Aarvi Encon falling/rising?

As of 01-Aug, Aarvi Encon Ltd is experiencing a significant decline in its stock price, currently at 0.00, reflecting a change of -104.05 (-100.0%). Today's price summary indicates a falling investor participation, with a delivery volume of 4.06 k on 31 July, which has decreased by -42.74% compared to the 5-day average delivery volume. Despite the company having a low debt-to-equity ratio of 0.02 times and reporting positive quarterly results, such as the highest net sales of Rs 144.45 cr and an operating profit to net sales ratio of 3.08%, the stock has not generated any returns over the past year, and profits have fallen by -11.5%. This combination of factors suggests a lack of investor confidence, contributing to the stock's downward movement.
Broader market context data is not available for comparison against benchmark returns. However, the stock's long-term growth prospects appear poor, as indicated by an annual operating profit growth rate of only 8.22% over the last five years. The attractive valuation with a price-to-book value of 1.2 and a return on equity of 8 may not be sufficient to offset the negative sentiment surrounding the stock, especially given the recent decline in investor participation and the overall lack of positive returns.
