Short buying: Investors predict that the stock price will rise, but their own funds are limited, so they can't buy stocks in large quantities, so they pay part of the deposit first, and raise funds from banks through brokers to buy stocks, and sell them to get differentiated income when the stock price rises to a certain price.

2. Short selling: Investors predict that the stock price will fall, so they pay the mortgage to the broker and borrow the stock to sell it first. When the stock price falls to a certain level, buy the stock and then return the borrowed stock to obtain the balance income.

3. Dishwashing: Speculators first cut prices sharply, causing a large number of small investors (retail investors) to panic and sell stocks, and then raise the stock price in order to seize the opportunity.

Generally speaking, the rebound of stocks is less than the decline. Usually, when they rebound to about one-third of the previous decline, they return to the original downward trend.

5. retracement: in the stock market, the stock price showed an upward trend, and finally reversed and fell back to a certain price due to the rapid rise of the stock price. This adjustment phenomenon is called retracement. Generally speaking, the return range of stocks is smaller than the rising range. Usually, when it falls back to about one third of the previous rising range, it will reverse and return to the original rising trend.
