How to calculate the ups and downs?

-2.77 means that the stock fell by 2.77%.

1. Calculation method: price = (current price-closing price of the previous trading day)/closing price of the previous trading day * 100%.

2. Rise and fall: Compare the daily closing price with the previous day's closing price to decide whether the stock price will rise or fall. Generally, it is indicated by "+"and "-"on the bulletin board above the trading desk. The percentage range of the latest stock price of the day compared with the previous day's closing price (or the previous day's closing index) is positive, negative or flat.

3. "Increase" refers to the increase of this stock. If the stock price rises by 10.00%, it is generally the daily limit of the stock. If the increase is 0, it means that there is no increase or decrease today, and the price is the same as the previous trading day.

"Up" refers to the current decline of this stock. If the stock price falls by 10.00%, it is generally the limit of the stock. If the increase is 0, it means that there is no increase or decrease today, and the price is the same as the previous trading day.

Extended data:

The rise and fall of stock price is determined by the profits created by listed companies for shareholders in the long run, but it is determined by the relationship between supply and demand in the short run, and the factors that affect the relationship between supply and demand include people's profit expectations of the company, artificial speculation by large households, market funds and policy factors.

Value investment depends on whether investors think a stock is undervalued or overvalued, or whether the whole market is undervalued or overvalued. The simplest method is to compare the price-earnings ratio, dividend and yield index of a company with the average level of competitors in the same industry and the whole market.

If a company's technical indicators are lower than the market performance, you should ask yourself why. There are usually some factors you don't understand, such as potential losses, poor management, declining market share, employee problems and so on.

Price fluctuation is a description of price fluctuation, expressed in%. Price fluctuation = price fluctuation/yesterday's closing price * 100%.
