Today's market has pulled back; there may be opportunities for buying at lower prices in the afternoon. After the holiday, there may be an upward trend, so it is essential to seize high points for timely selling, and avoid increasing positions at high levels; one must be cautious of risks even in a bull market.
Large capital usually enters the market only during deep pullbacks, so it is not advisable to casually increase positions in broad-based index funds recently; wait for opportunities after a significant drop.
Major market trends often start from the bottom, so patience is required to wait for the right moment to position oneself.
