Bay & Wall Street are more reactionary.

Just read this headline:

This Wall Street Predictor Is Worse Than Your Weatherman

The examples above underscore how difficult it is to make accurate predictions in the stock markets. Weather forecasts offer a good comparison. They rely on modeling just like financial projections, but they only go out five or 10 days in advance because meteorologists can't accurately predict the weather after that. To give the high temperature for a year from now would be utter folly. Similarly, financial analysts have no idea what events will take place, macro or company-specific, to alter the value of a stock, nor can they predict the mood of market, which can affect stocks as much as fundamentals.
