Bloomberg with a piece saying stocks falling today "extending last week's plunge, as factory-gate price data fueled concern the economic slowdown is deepening"

Mike had the weekend PPI and CPI data

It's the PPI data the Bloomberg article is referring to

'Pessimism is the dominant sentiment," said William Wong, head of sales trading at Shenwan Hongyuan Group Co. in Hong Kong. "The PPI figure confirms the economy is mired in a slump. Market conditions will remain challenging given weak growth and volatility in external markets and the yuan's depreciation pressure."

Weekend PPI driving today's stock market falls? Really? Can' see it myself. Ah well.
