Why is Expo Engineering falling/rising?

As of 06-Oct, Expo Engineering and Projects Ltd is currently priced at 99.45, reflecting a decline of 1.5, or 1.49%. The stock has been underperforming, having fallen for the last two days with a total decrease of 2.55%. Although it opened the day with a gain of 4.01% and reached an intraday high of Rs 105, it also touched a low of Rs 98.25. The stock's performance over the past week shows a decline of 1.13%, while it has seen significant gains over the longer term, including a 46.44% increase year-to-date and a remarkable 691.17% rise over the past three years. However, there has been a notable drop in investor participation, with delivery volume decreasing by 41.04% compared to the five-day average, indicating a potential lack of confidence among investors.
In the broader market context, the Sensex has increased by 1.77% over the past week, contrasting with Expo Engineering's decline. This suggests that while the overall market is performing well, Expo Engineering is lagging behind. The stock's recent performance, particularly its consecutive falls and underperformance against the sector, may be contributing to its current price movement. Despite its strong long-term returns, the recent short-term trends and declining investor interest could be influencing the stock's downward trajectory.
