The SPY and QQQ both hit a wall at their 30 day averages on Wednesday. The key for me is whether they can close above this key average or head back down. Check out this daily chart of the QQQ. Note how the QQQ could not break above its 30 day average (red line). If it closes Thursday above this line, I would become more confident that the short term trend is reversing up.
IBD: correction over; 18th day of $QQQ short term down-trend
IBD says Tuesday was a follow through day and marked the end of the correction. I will wait for the GMI to turn positive before I re-enter the market. I still do not trust this rebound yet.
