A Negative Earnings Revision Is No Reason To Sell Stocks

Because of this well-known record, markets have gotten used to negative earnings revisions. In other words, this specific type of bad news is generally priced into the markets and is not a good reason to sell stocks.

Estimates for 2014 are already tumbling.

"The above-noted S&P 500 2014 EPS estimate downgrades are in fact no worse than in-line with the long-term (post-1987) "average annual earnings estimate revision trend" -- i.e. estimates typically "start high" and are whittled down over time -- which itself implies roughly another 7.5% downside to 2014 EPS before the "typical" revision process will have run its course (Figure 36)," said Nomura's Michael Kurtz. "This would imply that bottom-up 2014 EPS eventually settle at roughly US$111.0/shr. -- a deeper cumulative downgrade than our own top-down modelling suggests, or indeed than we ourselves expect."

Kurtz is expecting $112.50/shr. in 2014 for the S&P 500. He sees the index ending next year at 1,925, up 7% from current levels.

This is not to say earnings aren't important for stocks. It's just that the markets know those forecasts are coming down.
