Suction is the production of a more or less complete vacuum with the result that atmospheric pressure forces fluid into the vacant space (OED definition)
To what extent did the big down moves in such markets as gold, Russia, Spain (down 24% on year), Italy (down 15% on year) and Europe cause the decline with a lag in US stocks. Is there a general phenomenon with which suction can predict declines in closely related geographic areas? How does the concept of substitute good enter into the fray. A substitute is defined as a good whose price rises as the other good rises A complementary good is one whose price declines as the price of the other good rises. Are bonds a substitute for stocks? The dollar? What are the predictive relations?
