JPMorgan analyst Ryan Brinkman views General Motors' Q4 results as strong and says cycle fears are overblown. GM highlighted several industry and company-specific factors that would mitigate the profit impact of any downturn in car sales, Brinkman tells investors in a post-earnings research note. He raised his estimates to the high-end of the automaker's guidance and tells investors "the sky is not falling" following yesterday's stock selloff. Brinkman reiterates an Overweight rating on GM with a $47 price target. The shares closed yesterday down 27c, or 2%, to $28.93.
