Many people are thinking about why the big fall, but in fact, the reason for the big drop is very simple, that is, early profit-taking

From 25,000 to 73,000 in October last year, it was only 5 months, not counting the inflow of only stocks, even if the amount of assets in the market was at least three times more than that, but their costs were mostly between 25,000 and 40,000 in terms of time. If you don't sell it, the profit will be lost, so it will trigger a sell-off.
This pullback will not be completed at the beginning of the 6, because the main cost is within 40,000, and the pullback will only be completed if the low-cost people sell to make the average cost of the market higher
I speculate that it will probably be between 49000-53000, and the pullback will be completed, and now the radical people can choose to go short, and the conservative ones should wait.
At last. The world economy is nowhere near as good as it seems, and if you go to the malls, many stores have closed, especially those with high added value.
