Why is Laurus Labs falling/rising?

As of 26-Aug, Laurus Labs Ltd is experiencing a decline in its stock price, currently at 865.80, which reflects a decrease of 7.25 points or 0.83%. The stock has been on a downward trend, having fallen for the last three consecutive days, resulting in a total loss of 2.67% during this period. Despite this recent decline, the stock has shown strong performance over the longer term, with a year-to-date increase of 43.74% and a remarkable 93.41% rise over the past year. However, the stock's delivery volume has decreased by 2.67% compared to the five-day average, indicating a drop in investor participation. While the company has demonstrated high management efficiency and impressive growth in net profit, the long-term growth prospects appear limited due to a modest operating profit growth rate of 7.84% over the last five years.
In the broader market context, Laurus Labs has outperformed the Sensex in the long term, generating significant returns compared to the benchmark. However, in the short term, the stock's performance has lagged behind the Sensex, which has only declined by 1.05% over the past week, while Laurus Labs has dropped by 2.13%. The stock's recent struggles may be attributed to its expensive valuation and a relatively low return on capital employed, which could be causing some investor caution despite its strong historical performance and high institutional holdings.
