How long does it take to start after the bottom is negative?

Half a month or a month.

When the stock fluctuates at the bottom, there is bad news again. The stock price will not rise, but the decline will be limited, but the main thing is to see the degree of bad news, whether it is a major bad news, if like LeTV, it continues to fall by the limit. , even hitting new lows is normal.

Being negative at the bottom of a stock is usually a deliberate panic created by big funds. Listed companies and bookmakers cooperate to use sudden bad news to suppress unsuspecting retail investors and other major players, creating the illusion that stock prices will continue to fall. The illusion induces them to sell the chips in their hands and then take over at a low position.
