Why are some stocks expected to come out in the interim report, with a pre-loss of more than 200%, and have not yet fallen?

This is mainly caused by the difference between the predicted loss range and the results of major market forces. For example, a market leader predicted a performance loss of 300%, and the actual loss was only 200%. Then the market leader will raise the stock price, because the previous stock price has been greatly suppressed by the market leader, but the result is "better", so the stock price will rise, but at this time, don't chase after it. It's only a short day or two.

On the other hand, when the pre-loss of a stock is only 20%, it falls, mainly because it exceeds the market expectation. The market (main force) originally thought that there would be no performance loss, so the result of performance loss came out, and of course it was sold off by the market.
