If a stock rises by one-tenth, the one-tenth increase is one-tenth of the original price. Is it true or false? It is correct.

Settlement of stock rises and falls

Rise and fall = (current price - closing price of the previous trading day) / closing price of the previous trading day * 100%.

Essentially, a stock is a "commodity" whose price is also determined by the intrinsic value (the value of the underlying company) and fluctuates around the value.

Stocks are like ordinary commodities. Their price fluctuations will be affected by the supply and demand relationship in the market.

Just like the pork sold in the market, when people want to buy more pork, but the supply of pork cannot keep up, the price of pork will definitely rise; when there are a lot of pork sellers in the market, the supply of pork will If the demand is greater than the demand, the price of pork will definitely fall.

The price fluctuation of the stock is as follows: at a price of 10 yuan/share, 50 people sell, but there are 100 buyers in the market, then the other 50 people who cannot buy will buy it at a price of 11 yuan If you buy, the stock price will rise, otherwise it will fall (due to space issues, the transaction is simplified here).

Calculation of stock increase percentage

(12.12-11.20) / 11.2 = 0.0821 = 8.21% This is the increase from yesterday's closing price to the closing price of previous days.

If there is a negative number in the brackets, then it is a decrease.

The real-time increase or decrease on the stock software is the increase or decrease of the current price to yesterday's closing price.

For example, yesterday’s closing price was 10. If the current price is 10.5, then the current increase is (10.5-10)/10 =0.05=5%; if the current price is 9.3, then the current decrease is (9.3- 10)/10 = -0.07 =_ 7%, which is a 7% drop!
