Corporate earnings have rebounded in recent quarters, growing 6.35% year-over-year in the S&P 500 after several years of decline. Analysts expect further modest earnings growth in 2017 and stronger double-digit growth beyond 2017, though estimates are often overly optimistic. While recent positive economic data and potential pro-business policies under Trump have boosted expectations, current stock valuations are very high by historical standards given the stage of the economic cycle in the absence of confirmed policy changes. Continued earnings growth and flexibility will be important for investors as policy developments unfold.
