This is not TA, just my common sense telling me watch out....I hope I am wrong. But My fear for Monday is a $1-2 Gap Down. It probably won't happen, but with all the weakness and down day today you might use extra cautious.
averaging in and out, selling puts to enter lower works best for me. Monday could be up, or down big. This should just be a slight technical correction, not a global market melt down. It's a good time to plan a trip to Argentina if one is so inclined.
I would never venture south of the border any more and I am Hispanic- I know better. I would go to Europe, esp England/France etc. I would feel safer in China/Japan than Mexico/South America. I would go to South Africa, but be very cautious there. I would even feel safer in North Vietnam than Mexico.
