Why is Zenlabs Ethica falling/rising?

As of 15-Jul, Zenlabs Ethica Ltd is experiencing a decline in its stock price, currently at 35.56, which reflects a decrease of 0.32 or 0.89%. The stock has underperformed its sector by 1.7% today and has shown a trend reversal after three consecutive days of gains. Despite a positive performance over the past week and month, with returns of 5.83% and 6.63% respectively, the stock has a year-to-date decline of 9.97% and a one-year return of -13.27%. The company has a weak long-term fundamental strength, indicated by an average Return on Equity (ROE) of 7.31% and a concerning annual growth rate of net sales at -3.02%. Additionally, the stock is trading at a premium compared to its peers, with a Price to Book Value of 2.2, which may deter potential investors.
In the broader market context, Zenlabs Ethica's recent performance contrasts sharply with the benchmark, as the Sensex has gained 1.79% over the past month and 5.67% year-to-date. The stock's consistent underperformance against the benchmark over the last three years, coupled with a significant drop in profits of 15% over the past year, further underscores its struggles. While there has been a rise in investor participation, as evidenced by an 81.92% increase in delivery volume, the overall sentiment remains negative due to the stock's weak fundamentals and high valuation relative to its peers.
