流通盘是指上市公司发行的股票总数量中，可以在二级市场进行交易的部分。具体来说，流通盘等于流通股本，是流通股的数量。流通盘的大小直接影响到股票的流动性，进而影响到股票的价格。一般来说，流通盘越小，股票价格越容易波动，而流通盘越大，股票价格波动性就越小。

在股票交易中，投资者需要考虑流通盘的大小。如果一只股票的流通盘很小，那么它的交投活跃度就可能不足，市场承接力就可能较弱，股价就可能被大资金操控。因此，投资者在选择股票时，会考虑流通盘的大小，以避免投资风险。

此外，流通盘的大小还会影响到公司的融资能力。如果公司的流通盘很小，那么它就难以通过增发、配股等方式进行再融资，因为这些方式都会增加流通盘的大小。因此，对于公司来说，扩大流通盘的大小也是非常重要的。

总之，流通盘是股票交易中非常重要的一个概念，投资者需要充分考虑流通盘的大小，以避免投资风险并做出更明智的投资决策。

Liquidity refers to the portion of a company's issued shares that can be traded on the secondary market. Specifically, liquidity equals to the circulating capital stock, which is the quantity of shares that can be traded. The size of the liquidity directly affects the liquidity of the stock, and thus affects the stock price. Generally speaking, the smaller the liquidity, the easier the stock price is to fluctuate, and the larger the liquidity, the smaller the price volatility.

In stock trading, investors need to consider the size of the liquidity. If the liquidity of a stock is small, its trading activity may be insufficient, market acceptance may be weak, and the stock price may be easily manipulated by large funds. Therefore, investors consider the size of the liquidity when selecting stocks to avoid investment risks.

In addition, the size of the liquidity will also affect a company's financing ability. If a company's liquidity is small, it may be difficult to raise funds through additional issuance or share allocation as these methods will increase the size of the liquidity. Therefore, for companies, expanding the size of the liquidity is also very important.

In summary, liquidity is a very important concept in stock trading. Investors need to fully consider the size of the liquidity to avoid investment risks and make more informed investment decisions.
