Because for nw, MERQ, QLGC and JCOM are a little wobbly MERQ may have a visit under $38, QLGC may revisit sub $30 and if these "visits" do not generate strong buying, it may be over for these. The one I mentioned are all near some nice support, if stopped the damage is not too great. Except for GPRO, these are also in nice uptrends.
