In December this year there will be a gathering of planets in a small part of the Zodiac. These planets will, one by one, line up with the centre of our galaxy. What makes this especially important is that Pluto, the slowest-moving of all the planets in our solar system, will be lined up with the galactic centre for the first time in nearly 250 years. This is therefore a potentially epoch-making event.
It is a process of detoxification [it turned out, of toxic debts]
there is an intense change afoot in the arena of state and corporate power. This applies particularly as Pluto - representing plutocracy - will be within one degree of the galactic centre at various points for the next year or so, and within two degrees for a while longer.
the worst case scenario is that the damage intensifies and becomes still more entrenched with even greater levels of passivity on the part of the general public. Abuse of state power and corporate power is ready to change during this aspect. It is up to the citizens of each country to make the changes work for them, rather than against them.
Economically, these cultural processes may well affect the economies of the countries involved, and their stock markets too. Shifts in mood in the national and international psyche may reflect [in]investments, spending habits, and levels of fear. Insurance, taxation, and corporate accountability may well be high on the agenda. From October onwards, peaking in December-January, then tailing off before returning around July-August 2007 for further review. It is most especially this latter period when, history shows, stock markets may be affected by the Saturn-Pluto trine, but in December 2006 when Saturn stations in the later degrees of Leo it will connect with the charts of several of the worlds largest stock markets. Whether that will manifest through institutional restructuring and reorganising, or through market fluctuations, or both, remains to be seen.
Looking at previous occurrences of Saturn-Pluto trines we find that the USA's Dow Jones stock market index has usually fallen, however we cannot even 'guesstimate' what may happen to world stock markets this time around. The situation is far too complex, not least because when Pluto was last conjunct the galactic centre in 1758/9 none of the world's stock markets existed, so we have no historical experience to draw upon. And, of course, the world was a very different place in the 18th century.

PS - Sorry for the errors - one is a typo, which has been corrected above, and the other is factually incorrect: in 1758/9 there were hardly any stock exchanges, and they were in rudimentary form compared to nowadays, but it's not true to say that there were none. Amsterdam and London both had stock trading going on at that time. Obviously though what was happening then doesn't give a guide to current times, since it was in a relatively simple system and relatively basic trading, and not a globally interconnected nor systemically complex form as things are now.
