Short selling in the economy is an investment term for stocks, futures, etc. For example, when you predict that a certain stock will fall in the future, you sell the stock you own when the current price is high (the actual transaction is (Buy a bearish contract), then buy when the stock price drops to a certain level, and return it to the seller at the current price, so that the price difference is your profit. Short selling is an operating mode in stocks, futures and other markets.
Being bearish on the economy, to put it bluntly, means publicly stating that one is not optimistic about the economy. Sometimes, in order to suppress stock or futures prices, bankers or institutions deliberately create negative data and research reports to make people panic and sell chips one after another, allowing the bankers themselves to collect cheap chips at low prices.
To summarize, although both of them mean that they are not optimistic about the economy, short selling is more focused on actually using chips or money to actually suppress selling in the market; while short selling is focused on creating negative news to bring negative effects to bullish opponents. Come to psychological pressure.
