Why is Uno Minda falling/rising?

As of 12-Sep, Uno Minda Ltd's stock price is currently at Rs 1,282.70, reflecting an increase of 2.7 points or 0.21%. The stock has been gaining over the last two days, with a total return of 0.88% during this period. However, it has underperformed its sector by 0.53% today and is 3.69% away from its 52-week high of Rs 1,330. The stock's performance over the past month shows a significant increase of 19.98%, while it has generated a return of 24.97% over the last year, outperforming the BSE500 index. The company's strong fundamentals, including a low Debt to EBITDA ratio of 0.98 times and impressive growth in net sales and operating profit, contribute positively to its stock movement. However, the stock's valuation appears expensive with a ROCE of 15.7 and a PEG ratio of 4.5, which may raise concerns among investors.
In the broader market context, the stock's recent performance contrasts with the benchmark, as it has declined by 1.23% over the past week while the Sensex has increased by 1.48%. Despite this short-term underperformance, Uno Minda has demonstrated strong long-term growth, outperforming the benchmark over various periods, including a remarkable 116.20% increase over the last three years compared to the Sensex's 36.25%. The high institutional holdings at 25.44% indicate confidence from larger investors, which may provide some stability. However, the recent decline in delivery volume by 37.81% against the 5-day average suggests a potential decrease in investor participation, which could impact future price movements.
