Stock trading is a very risky investment behavior, and there are no techniques that can ensure fast money-making and controllable risks. Making money quickly is often accompanied by high risks, which are likely to lead to huge losses. The following are some common misunderstandings and risks.： **1. Chasing up and killing down** -**Performance**: When you see stocks rising and stopping continuously or rising rapidly, you rush to catch up, hoping to get subsequent gains; and when stocks fall, you are eager to sell, for fear of further losses. -**Risk**: Chasing a rise is easy to stand guard at a high level after a short-term sharp rise in the stock price, and the subsequent stock price may fall rapidly; killing a fall often cuts the meat and leaves the market when the stock price is close to the bottom area, missing the opportunity to rebound. For example, after some popular theme stocks have risen and stopped continuously, once the market reverses, investors who chase high and buy may suffer heavy losses. **2. Listen to the news and trade stocks** -**Performance**: Rely on gossip, stock review recommendations, social media rumors, etc. to make stock trading decisions. -**Risk**: These sources are often inaccurate and lagging, and many times they are smoke bombs deliberately released by the main funds. Blindly following the news to buy stocks may just fall into the shipping trap of the main force, causing the stock price to plummet after buying. For example, after the news of some unconfirmed company reorganization broke out, the stock price rose briefly, but if the final reorganization fails, the stock price will fall sharply, and investors who bought on the news will lose a lot. **3. Over-leveraged trading** -**Performance**: Use highly leveraged margin financing or participate in off-site capital allocation to be small and broad. -**Risk**: While leverage amplifies gains, it also magnifies risks exponentially. Once the market moves unfavorably, investors may soon face the risk of bursting positions, not only losing all their principal, but also carrying huge debts. For example, during the sharp decline in the stock market in 2015, many investors who used high leverage suffered heavy losses or even lost their money. Stock investment should be based on adequate research and analysis, reasonable asset allocation and long-term investment philosophy, and should not seek unrealistic high-risk techniques for making money quickly. Please be sure to treat stock trading with caution, invest rationally, and avoid blindly taking risks.
