Review title: Good Story book but not practical
Product review: Today is Nov 14th 2005, Tyson food reported it quartely profit surged to 49 percent, as operating income surged in its chicken and pork businesses also because of record corn production last year and this year, there is ample supply (inventory) of corn that should benefit Tyson food further as it can buy corn at cheap prices.But... stock declined by 6% in the premarket trading. Reason..."Market is effecient". There are thousand of analysts who analyze these information and incorporate them in their stock price estimate. If result surpasses expection, stock price will rise else it will fall.
