As a follow-up to comments received on my recent post concerning Grand Trines, it is interesting to note that in March of 2010 and again in April of 2011 there occurred T-Square formations in which Saturn was 180 degrees opposite Mercury and both Saturn and Mercury were 90 degrees square to Pluto. A quick search using Solar Fire software suggests this is not a common alignment (as would be expected given the slow moving nature of Saturn and Pluto). In both cases, a market selloff occurred within a few weeks after the T-Square event. It remains curiously interesting how market sell-offs tend to be fore-shadowed by planetary alignments that are not too common. How these alignments scientifically influence the emotions of market participants to create the sell-offs remains the burning question….
