Second, bearish: refers to investors looking at the future of bad markets or stocks. A stock has fallen, and outsiders feel that it will continue to fall for a while and dare not buy it.
"bearish" and "bullish" refer to investors' judgments on future market development. Judgment is based on the quantitative accumulation of "positive" and "negative" in policies and news. If the positive is stronger than the negative, it means bullish, on the contrary, it means bearish, and the battle between long and short will generate investment opportunities. "More" and "empty" mean that investors buy or "empty".
Therefore, to put it simply, "bullish" and "bearish" are investors' subjective judgments on the risks of the market system, and "long" and "short" are rational choices of market operation behaviors (buying and selling) based on this judgment.
