In stock market investment, the concepts of profit and loss are quite intuitive. Simply put, profit is an increase in the account balance, while loss is a decrease in the balance. The calculation of profit and loss is mainly based on the purchase and sale of stocks. Whether it is the overall account profit or loss or the profit and loss of a single position, it is a key indicator to measure the investor's investment performance within a specific period of time.

The total profit and loss of the account, that is, the sum of the profits and losses of all positions and liquidated stocks, reflects the overall profit and loss of investors over a period of time. Position profit and loss specifically refers to the profit or loss caused by changes in stock prices during the period when investors hold stocks. To understand this information, investors have two ways for reference:

First, they can calculate the net inflow or outflow of transfer funds by checking bank-securities transfer records, and then compare it with the market value of the current securities account. Get the account profit and loss value. This method visually displays the relationship between capital inflows and outflows and changes in market value.

Secondly, directly contact the securities company where the account is opened, use the counter netting function to inquire about the detailed inflow and outflow of funds, and then compare it with the total assets of the account, and you can also get the total profit and loss. The advantage of this is to directly obtain professional transaction data with higher accuracy.

In general, position profit and loss is not just the actual money earned. It includes all gains and losses of investors during the period of holding stocks, and is an important part of evaluating investment performance. Through the above two methods, investors can clearly understand their investment status.
