Why is Knowledge Marine falling/rising?

As of 01-Jul, Knowledge Marine & Engineering Works Ltd is experiencing a decline in its stock price, currently at Rs 1,565.60, which reflects a decrease of Rs 9.4 or 0.6%. The stock has been on a downward trend, having fallen consecutively for the last five days, resulting in a total decline of 9.4% over that period. Today's trading saw the stock reach an intraday low of Rs 1,530, indicating a significant drop of 2.86%. Additionally, the stock's performance over the past week shows a stark contrast to the Sensex, which has increased by 2.00%, while Knowledge Marine's one-month return is slightly positive at 1.51%. Despite a high management efficiency indicated by a return on equity of 25.44% and strong sales growth, the stock's valuation appears expensive, and institutional investor participation has decreased, contributing to the negative sentiment surrounding the stock.
Broader market context reveals that Knowledge Marine's recent performance is not aligned with the overall market trend, as evidenced by its significant underperformance compared to the Sensex, which has gained 2.76% over the past month. The company's year-to-date return of -31.03% starkly contrasts with the Sensex's positive return of 7.11%. The falling participation from institutional investors, who have reduced their stake, further exacerbates the stock's decline, as these investors typically possess greater analytical resources. This combination of declining stock performance, reduced investor participation, and a high valuation relative to earnings suggests a challenging environment for Knowledge Marine, leading to its current price decline.
