After exceeding expectations for more than two years, earnings this year seem poised, at last, to reflect the plodding nature of the economic recovery. In 2010 and 2011, even as the real economy managed only a paltry 2.4% average annual rate of expansion, the earnings of S&P 500 companies soared, rising more than 47% in 2010 and almost 20% in 2011. Such a pattern could not persist, and this year the slow fundamentals will almost surely assert themselves. Even so, it would be a mistake to read matters too pessimistically. There certainly is nothing ominous in the pattern. It is well-established historically that earnings should come into line with slower-growing revenues in this, the third year of economic recovery. Besides, this year’s probable 10% earnings growth, though only about half the pace in 2011, is sufficient to sustain the stock market rally.
