See charts below, the bear markets' ultimate rebound target has been the MA200. After which, if bear market continues then the rebound should end around the MA200, while if the bear market was over then the price should be further away from the MA200, at the most, kiss the MA200 goodbye before going up and up, see the year 2009 case.
So accordingly, if keeps going down the next week, then the stock market's battle of Stalingrad - the MA200 would officially start. The chart below is my wild-est-est-est guess, assuming the worst case to test the May lows then back to kiss the MA200, and then the main watch point - whether bulls could regain the control of the MA200 which at the current stage, I have no evidences saying bulls would be successful or not, will need wait and see.
