They are on support area for quite some time, you got to play both the market and individual issues. Apart of that "defense" should be counter market like gold. In edit, by the Way, ATK was just dumped here at $37.45 (-$.08)since it was a second visit under $37.50 indicating support may be waning. And since LLL went, I also dumped ATK at $49.17 ($.30) since I often trade them together.
