Only news, or a ridiculously low SP, will spur buying which is needed to reverse
this decline. And we could have another week or two without news if no 8k after hours today. Best advise there is- if the decline bothers you, dont watch it!! No experienced investor sells into a major decline. If you have to, go hide under the bed until June or so. Or sell everything and buy, buy, buy!! Thats my plan if things get truly crazy. Or point at my portfolio screen and laugh- it helps.
