One stock refers to the minimum trading amount set for each stock. The number of shares per lot varies from company to company, ranging from 200 shares to 2,000 shares, but 1,000 shares per lot is the most common. Listed companies determine the number of purchases and sales per lot. According to the regulations of China's Shanghai Stock Exchange and Shenzhen Stock Exchange, one lot equals one hundred shares.
As for the origin of the unit of "one lot" of stocks, there is a saying that because stocks used to be paper-based, buying 100 shares was enough to get them all in one hand, so the stock unit gradually became "one lot".
The number of shares in one lot of stock has a certain relationship with the stock price. Generally, stocks with a large stock price have a smaller number of shares per lot, while stocks with a smaller stock price have a larger number of shares per lot. The term "odd lot" refers to stocks that are less than one lot (the minimum trading unit).
In addition to the stock market, one lot is used as a unit for foreign exchange markets and futures. Although one lot is used as a unit, different stock markets, foreign exchange markets, futures, etc. have different quantities.
The price of one stock is generally determined by several factors:
1. Number of shares per lot
2. Price per share
< p>3. Transaction fees (such as brokerage commissions, handling fees, etc.) and taxes (including exchange levies, Securities Regulatory Commission levies and stamp duties).
