China has over extended its economic production for years, trying to maintain a 7% growth rate. Their real estate market has been completely phoney with huge ghost cities built and ready for occupancy, but no buyers.
Their economy is due a correction, and that will hurt our stocks also, but I doubt it will get as bad as 2007 very soon, unless western banks have been selling them Default Trade Swap contracts on their real estate.
Obama has pumped our stock market up with cheap interest, QE, and bullshit government stats. I would be surprised if the market rolled back about 20% over the next month to a year or so, but I doubt it will go under 14000 for a few years if it ever does again.
