In short-term trading, there are nine situations where it's advisable to sell stocks. 1. Price and volume divergence: Prices rise, but trading volume gradually shrinks, or new highs are reached with lower volume than the previous peak, indicating insufficient follow-up buying. 2. Huge volume but stagnant price: High volume and turnover at relatively high levels, but the stock price rises little or not at all, indicating that selling pressure is gaining dominance. 3. The upward angle on the intraday chart slows down, changing from a straight upward surge to a gradual, oscillating rise. 4. Deeper and longer pullbacks: Each pullback low is lower than the previous one, and the rebound is weak. 5. Inability to break through key levels: Repeated attempts to break through price levels fail to hold or maintain their position, and buy orders below are absorbed without new buying power. 6. Individual stock rising alone, with weak sector-wide follow-up. 7. Lack of a fixed selling standard, operating solely based on feelings, greed, and fear. 8. Inability to hold onto stocks after a small rise, missing out on potential winners. 9. Greedy holding on, turning profits into deep losses.
