Why is Sumitomo Chemi. falling/rising?

As of 04-Sep, Sumitomo Chemical India Ltd's stock price is currently at 581.50, reflecting a decrease of 7.95 points or 1.35%. The stock has underperformed its sector by 0.46% today and has experienced a trend reversal, falling after three consecutive days of gains. The stock's performance over the past week shows a positive return of 2.47%, but it has declined by 8.76% over the past month. Despite a strong year-to-date return of 8.69% and a one-year return of 11.72%, the stock's recent movement is influenced by a decrease in investor participation, as evidenced by an 8.98% drop in delivery volume compared to the five-day average. Additionally, while the company boasts high management efficiency and low debt levels, its long-term growth prospects appear poor, with net sales growing at only 6.60% annually over the last five years.
Broader market context indicates that while the stock has outperformed the broader market, which has seen a negative return of 4.38% over the past year, its recent decline may be attributed to its high valuation relative to peers, as indicated by a Price to Book Value of 10.1. The stock is trading at a premium compared to historical valuations, which may deter some investors. Furthermore, the stock's moving averages indicate a mixed trend, being higher than longer-term averages but lower than the 20-day moving average, suggesting potential volatility. Overall, the combination of declining investor interest and concerns about valuation may be contributing to the stock's current downward movement.
