Open position refers to the number of securities held by investors. For example, stock opening is the number of shares held by investors, and fund opening is the fund share held by investors.

For example, if an investor buys 10000 shares, then the investor's position on a stock is 10000 shares, and the position will change with the investor's buying or selling. After all the shares are sold, the position will be zero.

The larger the position of general investors, the greater the capital invested, and thus the higher the investment risk, but this is not absolute, but relatively speaking, investors with large positions will generally have more market value.

Investors can combine trading volume and positions to analyze individual stocks:

1. When the trading volume gradually increases, the positions also increase synchronously, and the price rises, indicating that the trading of the stock is relatively active that day, and the strength of many parties is greater than that of the short side. Although both long and short sides are adding positions, new buyers are actively adding positions and chasing up and down, which means that many parties have higher views on the upside of the market outlook;

2. When the trading volume increases, the positions also increase, and the price falls, indicating that the trading of the stock is relatively active that day, and both sides in the market are increasing their positions, but the short positions are actively adding positions to chase up and sell, and the short positions are temporarily stronger, and the market outlook may continue to fall.

3. If the number of positions is reduced, that is, the number of stocks held in the market is decreasing, it means that the number of stocks sold in the market is increasing and the funds are flowing out. This is a bearish signal, and the probability of stocks falling later is high. Investors should wait and see or sell stocks in short positions.

In addition, the cost of holding a position refers to the price at the time of purchase, generally including the handling fee. If you buy stocks or funds at one time, the cost of holding positions will not change, but if you increase or decrease positions during the holding period, the cost of holding positions will change with the prices of increasing and decreasing positions.

Generally speaking, if the cost of covering positions in the market outlook is higher than the first purchase cost, the cost of holding positions will also increase; If the cover price is lower than the first purchase cost, the position cost will be reduced.
