1、 How is the cost of making T stocks calculated?

In the A-share market, investors who buy and sell the same stock multiple times will find that their holding costs will increase or decrease. This is mainly because the profit and loss of each time the investor makes t will be diluted into the remaining stocks of the investor. The calculation formula for the cost of making t in stocks is=(the transaction amount of all buying and selling stocks+all buying and selling transaction fees - the transaction amount of closing and selling stocks)/the remaining number of stocks.

For example, if an investor buys 1000 shares of a certain stock at a price of 10 yuan, and when the stock price rises to 12 yuan, sells another 500 shares, with a handling fee of 10 yuan, then the cost of the investor after t=(1000 × 10+10-12 × 500)/500=8.02 yuan. Compared with the original 10 yuan, the cost has decreased by 1.98 yuan; If the stock price drops to 8 yuan after the investor buys, and the investor sells 500 shares with a handling fee of 10 yuan, the cost of investing after t=(1000 × 10+10-8 × 500)/500=12.02 yuan, which is an increase of 2.02 yuan compared to the original 10 yuan.

2、 How to operate stocks?

1. Leave a portion of the warehouse for T

Keeping a portion of the bottom position for T refers to investors taking advantage of the volatility of individual stocks on the day to buy and sell the same number of stocks, that is, sell high and buy low. This requires investors to hold the stock originally and not sell all of it.

For example, Xiao Li already holds 1000 shares of the stock, and the stock price fluctuated greatly on that day. When the stock price rose to 10 yuan, Xiao Li sold 500 shares in his hand. After selling, the stock price fell. When the stock price dropped to 9.5 yuan, investors bought another 500 shares. This type of intraday trading did not change Xiao Li's shareholding, but through high selling and low buying operations, Xiao Li earned the price difference: profit=(10-9.5) × 500=250 yuan.

2. Sell the bottom position and do T

Selling the bottom position to do T is similar to keeping a portion of the bottom position to do T, which involves buying and selling the same number of stocks, that is, high selling and low buying operations. However, investors are required to sell all the stocks they originally held, and their predictions of individual stock trends must be very accurate.

For example, Xiao Li, who holds 1000 shares of the stock, believed that there would be a short-term adjustment when the stock rose to 10 yuan, so he sold the 1000 shares in his hand. When the stock price fell to 9.5 yuan, he believed that the stock had almost recovered and bought another 1000 shares. By doing this T, Xiao Li earned a price difference of 500 yuan on the same day.

In summary, we know that investors must hold stocks as a prerequisite for conducting stock trading, and stock trading requires a lot of skill. If we conduct reverse trading during this round of trading, we will also need to calculate the amount of money lost in this part.
