Since this Thursday is Quadruple Witching Day, I expected high volatility, so I intended to wrap things up before Wednesday

‌The rebound that started on 8/11 was followed by a sharp crash as soon as the KOSPI crossed the 7200 level on 8/18, so the memory is still vivid. I was hoping it would break out of the range this time, but it's not happening. It seems to be a definite short-term trading range.
For now, tomorrow looks like it will be a day of sector rotation, so I've bought small amounts of a few stocks. I'll have to watch them closely to find the right entry points.
