Why is Trent falling/rising?

As of 19-Sep, Trent Ltd. is experiencing a decline in its stock price, currently at 5,079.45, reflecting a decrease of 65.05 points or 1.26%. The stock has underperformed its sector today by 1.65% and has been on a downward trend for the past two days, with a total decline of 2.49% during this period. Over the last week, the stock has decreased by 0.95%, and its performance over the last month shows a significant drop of 7.60%. Despite a strong long-term growth outlook, with net sales increasing at an annual rate of 43.59% and a high return on equity (ROE) of 15.22%, the stock's valuation appears expensive with a PEG ratio of 4.4. Additionally, it has underperformed the market over the past year, with a return of -30.63% compared to the broader market's decline of only -0.67%.
In the broader market context, while the Sensex has shown a positive return of 0.88% over the past week, Trent's recent performance indicates a stark contrast, highlighting its struggles relative to the benchmark. The stock's liquidity remains adequate, with a delivery volume increase of 23.05% against the five-day average, suggesting some investor interest despite the price decline. However, the high institutional holdings at 36.93% indicate that these investors may be cautious given the stock's expensive valuation and its significant underperformance compared to peers. Overall, the combination of high valuation concerns, recent price declines, and underperformance against the market contributes to the stock's current downward trajectory.
