Why is Hyundai Motor I falling/rising?

As of 21-Aug, Hyundai Motor India Ltd's stock price is currently at 2,449.00, reflecting a decrease of 35.7 points or 1.44%. The stock has been underperforming recently, having fallen consecutively for the last two days, resulting in a total decline of 5.26%. Despite this short-term downturn, the stock has shown strong performance over the past week and month, with returns of 9.77% and 14.44%, respectively. However, today's trading volume indicates a decline in investor participation, with delivery volume down by 8.18% compared to the five-day average. The company's strong long-term fundamentals, including a high return on equity and low debt-to-equity ratio, suggest potential for future growth, but recent flat results in net sales may be contributing to the current price decline.
In the broader market context, Hyundai Motor India Ltd has outperformed the Sensex significantly over the past week and month, with respective returns of 9.77% and 14.44% compared to the Sensex's 1.74% and -0.24%. However, the stock's recent performance contrasts with the overall market sentiment, as it has underperformed its sector today by 1.24%. The increase in institutional investor participation, which has risen by 0.66% over the previous quarter, indicates a positive outlook from more knowledgeable investors, yet the stock's current decline may reflect short-term market fluctuations rather than a fundamental weakness.
