Why is Uno Minda falling/rising?

As of 09-Sep, Uno Minda Ltd's stock price is currently at 1,285.20, reflecting a decrease of 20.55 points or 1.57%. The stock has underperformed its sector today by 1.75% and has experienced a trend reversal after three consecutive days of gains. It is currently 3.49% away from its 52-week high of Rs 1330. Additionally, the stock's delivery volume has decreased by 10.85% compared to the five-day average, indicating falling investor participation. Despite a strong long-term growth trajectory with net sales increasing at an annual rate of 31.47% and a low Debt to EBITDA ratio of 0.98 times, the stock's recent performance may be impacted by its expensive valuation, as indicated by a PEG ratio of 4.5 and a relatively high enterprise value to capital employed ratio of 9.5.
In the broader market context, Uno Minda's short-term performance has been less favorable compared to the Sensex, which has risen by 1.18% over the past week while Uno Minda has declined by 1.30%. Although the stock has shown strong long-term performance with a 21.59% year-to-date return and has outperformed the BSE500 over various time frames, the recent decline suggests that investors may be reacting to the stock's valuation concerns and reduced trading activity. The high institutional holdings at 25.44% indicate that more sophisticated investors are involved, but the current market sentiment may be weighing on the stock's price.
