Why is SML ISUZU falling/rising?

As of 06-Aug, SML ISUZU Ltd's stock price is currently at Rs 3,522.70, reflecting a decrease of Rs 55.2 or 1.54%. Today's price summary indicates that the stock opened with a gain of 2.01% but has since fallen after three consecutive days of gains, touching an intraday high of Rs 3,649.85 and a low of Rs 3,456.05. The stock has outperformed the sector over the past week and month, with returns of +4.31% and +29.28%, respectively. However, there has been a notable decline in investor participation, with delivery volume dropping by 54.61% against the five-day average, which may have contributed to the recent price decline.
In the broader market context, SML ISUZU's performance contrasts with the Sensex, which has seen a decline of 1.15% over the past week. While SML ISUZU has shown strong year-to-date returns of +150.44% compared to the Sensex's +3.08%, the recent trend reversal and falling investor participation suggest that the stock may be experiencing profit-taking after a significant rally. Despite trading above its moving averages, the liquidity remains adequate for trading, indicating that while the stock has been strong overall, short-term fluctuations are impacting its current price.
