After moving higher in early trading, the markets took a huge dive finishing just barely off lows. This is a big warning for all investors that our enormous rally might be coming to an end.

I’ve got 5 red arrows marking the sell-off days in the last several weeks. By IBD standards, we are looking for a follow-through day where the market will continue to show weakness and close near lows on decently high volume.

Be cautious and take profits.
