A total of 22 companies, 4% of the S&P 500 market cap, have reported 4Q12 results. Of these, 64% have topped revenue estimates and 68% topped earnings estimates (considerably lower than average). Aggregate earnings results have exceeded estimates by 1%, revenues have missed by 0.5%, and blended margins are down 12bps y/y. As Barclays' Barry Knapp notes, the last several quarters, earnings seasons have generally been characterized by revenue misses, earnings beats (but by a shrinking amount), and negative guidance; as a result, there has been a negative skew to stock prices. In other words, in the immediate aftermath of the report, earnings beats are marginally outperforming the market, while misses get hammered, primarily due to weak forward guidance. The sustainability of earnings growth remains key given the weak top-line environment and these three self-explanatory charts should hopefully put some fundamental color around the perspective that earnings season will be a negative for the market overall.
