He has good quotes.

We have plenty of information, but we are desperate for wisdom.

Sir John Templeton made his money during maximum pessimism.

Their q3 report was basically good but since it wasnt amazing like how the analysts predicted, the stock tanked 13%.

One article said the market 'went wild', but overall its been a small up day.  Excitement over nothing.

Sp500 is almost back to its all time highs, filling the 10% drop.  Probably gearing up for another big drop since people have no stable confidence.
