In the stock market, heavy volume usually occurs in the process of price rising or falling. When the stock price rises, the turnover suddenly increases, which may mean that the market demand is strong, and the buyer actively buys and pushes the price to continue to rise. On the contrary, when the stock price falls, the turnover suddenly increases, which may mean that the market is under great selling pressure, and the seller actively sells, pushing the price to continue to fall.
In futures or other trading markets, a large number of transactions may also indicate changes in market trends. The sudden enlargement of trading volume may be due to the strong expectations of market participants on the price trend, or it may be due to some unexpected events leading to changes in market sentiment.
It should be noted that heavy volume does not always mean the reversal of market trends. In many cases, the volume of transactions may only be part of the normal fluctuation of the market. To accurately interpret the trading volume, it needs to be comprehensively analyzed in combination with other market indicators and information. In addition, in different trading markets and varieties, the specific meaning and influence of heavy volume may be different, so when analyzing and explaining the phenomenon of heavy volume, it is necessary to analyze it according to the specific situation.
